"All the gates of the well sealer have to be tested for pressure. "The overseer's unequivocal order.

Lu Xiangfei, the drilling captain of Dahua 505, was full of bitterness: "More than 200 gates, try it like this, you can't finish it in one day, in fact, the standard of our blowout preventer is higher than that of other companies, and now the time is so tight, otherwise, let's try the main gate, and then how about 10 random inspections?"

"Our standards are high, and the oil and gas pressure in the Azijiu oilfield is even higher. In case of another blowout, we will all have to go around without food. If it weren't for the explosion-proof level of the drilling platform reaching level 2, maybe the drilling platform would burn up. "The supervisor is also an employee of Dahua Industrial, although he is on the same drilling platform with the drilling team, he and the drilling team belong to two units, which is equivalent to the existence of Party A, supervising Party B full-time, and requiring the other party to complete the work in accordance with the prescribed steps and documents.

At present, the Setan Oilfield, or several oil fields opened up by Dahua Industrial for the Russians, have a large number of drilling teams from the National Petroleum Company to do Party B for Dahua Industrial, that is, the pure construction party. Originally, there were many construction teams of Party B in the Aqijiu Oilfield, but it was only because of Su Cheng's order that all of them were changed to Dahua's own team.

However, the construction personnel have changed, but the institutional structure has not changed substantially, not only that, because Sioux City is staring closely, the Dahua employees in the whole region are twelve points careful, and the rules and regulations of safe production are hanging in the air like a golden rule, and a few people who dare to touch it. Even if they are not fired, they must be demoted, repatriated, and re-trained.

Lu Xiangfei finally climbed onto the "special contribution list", and naturally he didn't want to be kicked off because of disciplinary violations. He gritted his teeth and said: "The standard of pressure test is high, there must be valves that can't stand it, the materials we have stored now are not enough, and now we have to let the supply ship come over to deliver things, if there is no one in the warehouse, we must buy it now." ”

"No problem. The supervisor was also very clear about his responsibilities and agreed to it.

"I can't sleep anymore. Lu Xiangfei sighed. I went back and gave the order, and I did it myself.

The drilling crew wailed after no effect. I had to follow Lu Xiangfei and start debugging.

The drilling platform 505 is equipped with an annular well sealer, and the rubber core is a big weakness, which is operated by manual means and used well. It's also good to be able to do that.

Lu Xiangfei as the captain. Nature is the best in technology. He personally went into battle, one by one, and inspected and debugged all the more than 200 gates. Originally, it was expected to start drilling in the afternoon, but naturally it was not possible, but in fact, when it was time for dinner, the second round of inspections was only completed.

"Can you try it?" the supervisor was also anxious, and it was his first job to ask the entire drilling rig to do what it did. But time is also of the essence, and every Chinese person knows that the company has invested a lot in Azerbaijan. It costs a lot of money for people to eat and chew, and if it weren't for the safety regulations, he would also like to drill as soon as possible.

Lu Xiangfei looked at it again, wiped his sweat, straightened up and said, "Try it, prepare first." ”

There is no need for him to say it alone, the blocker, clean water, and sealing rubber ring are in place in an instant, and the high-pressure area is also surrounded by the warning belt.

Lu Xiangfei and the driller installed a cleaning head on the weighted drill pipe, and after cleaning the wellhead, they went down to the well and connected a buttered plug to the upper end......

Everything was ready to stop, and Lu Xiangfei shouted directly in a hoarse voice: "Close the valve, first 10 pressures." ”

10 pressures is 10 atmospheres, which is about 1 megapascal, which is a relatively small wellhead pressure.

The well sealer performed well at this value, which also proved that there was no problem with the installation, Lu Xiangfei nodded, and said again: "The mud pump hits 30 pressures." ”

The driller did so, and the engineer shouted with his pocket watch: "3 megapascal voltage regulation record for 10 minutes, start the timer." ”

Lu Xiangfei sat on the raised ridge with his ass, and his expression was relaxed.

The well sealer they are using now is produced by Dahua Industrial, which is not as good as the imported goods of the Setan Oilfield, but it is still much better than the domestic products. This is also determined by the different working environment, several domestic companies rarely go abroad to do projects, and the pressure of their own oil wells in China is small, and the similar well sealer can do. Sioux City, however, is bent on occupying several large oil fields, and has high requirements for various self-produced oil well equipment.

Historically, CNPC has encountered problems with Sudanese crude oil and other problems, but before that, they also used to import goods.

3 MPa is extremely easy for any kind of well sealer.

After 10 minutes of pressure stabilization, the driller asked Lu Xiangfei for instructions, and he and the deputy driller slowly increased the pressure of the mud pump to 20 megapascals.

Lu Xiangfei only stood up at this time.

The overseer also craned his neck and pinched his watch to check the time.

As soon as the hour hand reached three minutes, the mud began to bubble under the ram.

"Okay?" the supervisor turned his head and asked Lu Xiangfei, this level is not too bad, it is still on the verge of being usable.

Lu Xiangfei scratched his head: "Look again." ”

At the end of the 10-minute voltage stabilization test, the ram did not burst open, but the rubber core was closed but could not go back.

Lu Xiangfei said expectedly: "The mat is not good, this well sealer has to be pressed to 200, and it has to be replaced with a new one to have hope." ”

"I'm going to rush the supply ship. Without saying a word, the supervisor went to call.

At 12 o'clock in the morning, it was Dahua's own night boat that rushed over the supplies needed, and at this point in time, even if they did not pursue secrecy, the Azerbaijanis in Baku would not have sailed.

The supervisor went to inspect the materials on behalf of Party A, and Lu Xiangfei had already removed all 48 large screws of one inch and three. Not only the people of the drilling team, but also workers and engineers from other departments rushed over to help, or adjust the derrick, or help change the mat and oil.

Try again, the annular well sealer lasted for 5 minutes at 200 pressures, and the rubber core broke again.

"Change again. Lu Xiangfei had the expression of an old scalper. Only when the well sealer is in the best working condition can it withstand 200 atmospheres.

The 48 big screws were removed again, and all the pads were replaced. Regreas, then reinstall the gates.

Several workers were busy lying on the ground for more than an hour before adjusting the huge screws in place, and Lu Xiangfei checked them one after another, to achieve the maximum effect, the screws were too tight, and they were too loose. In the most exquisite fine processing workshop, there are regulations on how many turns of the screw, and some factories need a year and a half to achieve the yield rate of the design requirements is trying these fine things.

Offshore rigs don't require special precision. However, if the equipment is to be in the best condition, it must be particularly sophisticated.

The sea at night is cold and windy. Even if you wear four or five pieces of clothing. I still can't help but stomp my feet, lying on the cold steel surface to load and unload the huge screws is definitely a hard job, not to mention that the steel surface has been covered with mud pouring up.

Bitter, tiring and dirty, the work is basically declared unacceptable.

The supervisor looked at Lu Xiangfei, who was nearly 40 years old, shivering, and took off his gloves, felt the screws to twist them, and felt really sorry to go, so he simply took off his military coat. Under Lu Xiangfei's legs, he said, "If it doesn't work, let's do it tomorrow." Otherwise, let's purchase a batch of imported well sealers. ”

"The wellhead should also be adjusted, it is not much better, as long as this well can produce oil, I will be happy to do it for two more nights." Lu Xiangfei asked someone to bring another military coat over and change it for the overseer, and continued to keep his head shut.

In just a few minutes, the superintendent's lips turned blue, he put on his clothes embarrassedly, and said tremblingly: "Su Dong said, the oil field under our feet is one of the best oil fields in the world, what we want is the oil well with the largest output, and next time, it will definitely be crude oil under the well sealer." ”

"200 pressures, if the crude oil can still pop out......" Lu Xiangfei suddenly laughed twice, and then said, "I'll admit it." ”

In my life, the most promising opportunity to see a 10,000-ton oil well is now. The overseer, wrapped in his coat, suddenly sighed.

The general 10,000-ton well can not drill 200 atmospheres, so the high pressure that the 200-pressure well sealer can't get stuck must be a high-yield oil well.

Although the oil fields occupied by Dahua are good, there are only so many high-yield oil wells in the world, and it is really no luck for a company to meet two celebrations that are about to leave, and it is really impossible to say whose luck it is to break down into the drilling team.

The superintendent said a word, but it made everyone feel something, and the movements were unnaturally fast.

The third test, still failing.

The fourth test, still failed.

Each time, all parts are removed and gaskets and lubricants are reinstalled.

Repetitive and boring work makes people dizzy and almost vomited.

Lu Xiangfei frowned, stunned and persevered.

The rest of the drilling team gradually lost their grumbling mood and continued to work with the team leader.

The work on the platform is dirty, tiring and hard, and people who can't bear this pressure will definitely not be able to stay.

It took a total of 30 hours for the pressure test to be successful.

At this moment, the faces of the people on the entire drilling platform are wooden. On the one hand, it is blown by the cold wind, and on the other hand, it is stayed up all night.

Lu Xiangfei signed the documents given by the superintendent, and went back to sleep, and people from other departments tried their best to help clean up, and the next work was still the drilling team, and they couldn't sleep well.

The next day, a fragrance woke Lu Xiangfei up.

"What is it?" he looked down from the top bunk, where the area on the rig was expensive, and it was basically a dormitory like a school.

Sitting on the lower bunk was engineer Huang Donglei, a guy with an amazing belly who muttered while shaving lunch in a dish: "Su Dong is here, there is enough rice in his hands, half meat and half rice." ”

"Su Dong is here?" Lu Xiangfei repeated.

Huang Donglei couldn't figure out the point at all, and said crookedly: "You haven't eaten breakfast or lunch, right?" Hurry up, the soup will be returned in the canteen, and if it is too late, the wolves will drink it up." ”

"Why don't you eat in the cafeteria?"

"There are several executives in the headquarters, I ate two servings, I was a little embarrassed, so I said to give a basin to the drilling captain in the dormitory, Su Dong heard it, and asked about you. You see, when the cook hears that he is bringing you food, there is more meat than for others. Oh, if you go to the cafeteria and get asked, just say that I knocked over the rice bowl on the way. Huang Donglei said and ate at the same time, and the speed of both projects was extremely fast.

Lu Xiangfei jumped out of bed. Blocking Huang Donglei's waving chopsticks, he said, "You said that Su Dong asked about me?"

"yes, when you wake up. Just let you go and see him, otherwise, do you think the cook is willing to cook for me to bring back? Give me so much meat? You see, it's all small rib meat, and there is a good chance that the guy hid it. ”

"Su Dong asked me to wake up and go see him?" Lu Xiangfei was stunned for a moment, and said angrily: "Why didn't you say it earlier?"

"Didn't I say that?"

"I'll go now. Lu Xiangfei put on his pants and picked up his clothes. And he ran out.

Behind him, Huang Donglei said slowly: "Do you know where Su Dong is?"

Lu Xiangfei, who had already run out of top speed, braked suddenly, came back and glared at Huang Donglei and said, "It's not in the cafeteria?

"Oh. You know that. Huang Donglei blinked and lowered his head to plank rice.

"What do I know?"

"In the cafeteria, I thought you didn't know. Huang Donglei looked like a fool.

Lu Xiangfei went crazy and snatched his chopsticks angrily. Two-step run-up. Thrown directly into the sea.

Huang Donglei got up calmly, opened the drawer, took out a new pair of chopsticks, and said silently: "Fortunately, it is bamboo chopsticks, otherwise it will cause pollution." ”

Lu Xiangfei ran to the cafeteria as fast as he could, and sure enough, he saw Su Cheng and his party, the most conspicuous of which was Qin Shiwei, who was thicker than an iron pillar.

"Dean Qin of the Drilling and Oil Production Research Institute, what is he doing here?" Lu Xiangfei saw him. There was a wave of doubt, and then there was a surge of ecstasy.

Qin Shiwei is famous for his belief in time as life. Never socialize or accompaniment.

His strong body, superb technical skills, and the importance of Sioux City made Qin Shiwei as special as an activity boss in the eyes of grassroots workers—where he was, it usually meant some kind of activity.

On today's rigs, the only activity is oil production.

"Have a new plan?" Lu Xiangfei was not very awake from his sleep, and when he came to Su City, the ghost sent a message.

Su Cheng smiled, took the initiative to shake hands with him and said, "Captain Lu, I heard that you have been working for two days and one night in a row, are you tired?"

"I'm not tired, what's tired, that's what we're doing. Lu Xiangfei was a little proud, this is the boss asking us for warmth.

Qin Shiwei was not ready to give them time to greet each other, knocked on the table and said: "We have been checking the seismic data recently, and the condition of the exploration well in No. 507 is good, according to the latest feedback, I have re-made a stratigraphic map, and you can refer to it when you dig the well." ”

The stratigraphic map in the mid-90s was quite simple, but the basic functions were still complete, and Lu Xiangfei could understand it, tilted his head and thought for a while, and said, "So, we are connected to 503 below?"

"Yes, and if it's a little lower on our side, the yield may be higher. ”

"Then I see. ”

"Just understand, go. Qin Shiwei got up and began to collect the drawings.

Lu Xiangfei didn't understand again, and asked, "Where are you going?"

"Open the drill!" Qin Shiwei looked even more incomprehensible.

"Ah...... Ah!" Lu Xiangfei woke up like a dream, and hurriedly followed, thinking: These engineers from the University of Petroleum are all stunned, one is more unreliable than the other.

Su Cheng nodded around with a smile, and Shi Shiran followed behind.

Soon, the rig rumbled.

Since drilling started in November last year, Dahua Industrial has drilled three rounds of wells, with a total number of more than 10 wells, but the luck is not very good, most of them are dry wells. However, with so many oil wells bottoming, the geological conditions below are very thorough, and Qin Shiwei's drawings are still predicted, but once confirmed, it will be a standard underground crude oil distribution map.

In fact, the situation encountered by Dahua Industrial in the Aqijiu oilfield is the most common situation encountered by the oil industry, and more precisely, more than two of the 10 oil wells in the early stage have seen oil, which is quite good.

Only such a ratio can make the oil company persevere, otherwise, even if five dry wells are drilled, no oil star will be visible, and no matter how strong the oil company is, it will not be able to stand it. And the more drilled, the situation at the bottom is understood, and the probability of dry wells is smaller.

What Lu Xiangfei is doing now is more like a pure oil production well than an exploration well.

Under his command, the drilling team vigorously accelerated the footage in front of the drawings.

On the afternoon of June 16, the drill bit arrived at the designated position.

"Lower casing!"

"Test the oil!"

A series of actions, Lu Xiangfei's drilling team is extremely skillful.

Qin Shiwei stood in the position of the supervisor, staring at the movements below. What he wants is a successful test to illustrate the accuracy of the crude oil map.

Su Cheng's mood was also not calm, and he said with a poker face: "The situation looks good, you don't have to worry." ”

"What do I have to worry about. Qin Shiwei said in disguise: "If it doesn't succeed this time, if you want me to say, you have to take the road of exploring the side well......"

"Don't say anything unlucky. Sioux interrupted him.

Qin Shiwei was stunned: "Do you still believe this?"

As soon as he finished speaking, the drilling platform shook.

The derrick also made a "grunting" sound, as if there was a full belch on the bottom of the sea.

Qin Shiwei was stunned for a moment, and his expression instantly changed from a smirk to a stupid one, like a bear with a swollen face stung by a bee.

"It's ...... oiled"

Su Cheng muttered, his voice was completely muffled by the noise in his ears, and his mood was inexplicably calm.

It should be said that he didn't feel calm before, until now.

The exploitation of the Aqijiu oil field really consumed too much energy and too much resources of the group, and the oil production was a matter of course, but the dry wells that were not so natural caused too much pressure.

Not only Sioux City is under tremendous pressure, but the entire Dahua Industry is under tremendous pressure.

Even, these people who don't know about the Aqijiu oil field are under even more pressure.

After Qin Shiwei had a short period of dementia, he rushed up to check, Yang Ming, Li Shirong and the others lost their usual calmness, and looked ahead at a loss, all of them were happy and stupid.

"We're going to hit a second oil well at once, and a third, here and here!" Qin Shiwei ran back at some point, tearing open the drawings with a stain, and his fingers struck the two crosses marked with key points.

As if he had been awakened, Su Cheng nodded twice, then grabbed Li Shirong, and shouted at the top of his voice in the endless noise: "Keep it secret, keep it secret!"

ps: I am still in the state of the Chinese New Year, and I can't help myself.
