Chapter 554: The Green Curve

"Let's get started. Sha Mingyin habitually shouted, then pressed the open button with his thumb to open the valve in the depths of the oil well, and under the action of the pumping unit, the oil began to flow out.

The staff monitored each detector and valve, and on the computer in the control room, the crude oil extraction curve was gradually rising, which was the most advanced pumping system at this time. The three participating companies, from the Netherlands, France and the United Kingdom, are small and medium-sized companies with certain patents and technical capabilities, and like their Chinese suppliers, they are integrated into the supply chain of the Dahua Strategy Department under strict contracts.

As an oil company with assets of nearly 10 billion US dollars, although today's Dahua Industrial cannot be compared with giant elephants, it is also a young elephant with strength.

Controlling small and medium-sized upstream and downstream companies is an inevitable process for almost every young elephant to become a giant elephant.

Without the size and control of the baby elephants, Dahua would not have been able to get its hands on Azerbaijan's vast oil fields. Compared with the Setan Oilfield, it is like the difference between a rat and a rat's nest, and even the Daqing Oilfield, which has been in continuous production for half a century and still maintains production, is difficult to compare with the Azijiu oil area in the Caspian Sea region.

Sioux City has been preparing for this day for several years.

The tertiary oil recovery technology is one of the results of the preparation.

Su Cheng looked at the ups and downs of the pumping machine, and said confidently: "Let's go to the control room and wait, it's a little warmer there, and you can drink some black tea." ”

"Chinese black tea, that's a good thing, you have to try it. "BP's technical director, Ducat, wanted to go to the control room for a long time and responded immediately.

Shigeru Nishioka from the company said in a distrustful tone, "Do you have to go to the control room? If I can, I'd like to go to the wellhead to check it out." ”

His English is standard, with a notoriously unpleasant Tokyo accent. The word "check" bites particularly hard.

Wang Guan glanced at this Japanese man with a very bad face, and then said in Su Cheng's ear: "This is the technical commissioner of Japan International Petroleum Development Co., Ltd., and he is a little famous in Central Asia. ”

He has been in Kazakhstan for more than a year, and he is half an interpreter and half a local receptionist, worried that Su Cheng does not know the origin of Inpex, so he continued to whisper: "Although Inpex started relatively late, it has been operating in Central Asia for a while, and it has also won a small oil field in Russia. According to the analysis of the Information Agency, INPEX has a high investment in the Caspian region. It's an opponent. ”

Sioux City certainly knew about Inpex, one of the Big Nine that had ever acquired the Aziju Field, and was the only Japanese company to acquire the Aziju Oil Field that year. As a young oil company, it is full of momentum, much like Dahua Industrial...... Or rather. It's more like an extended version of Dahua Industrial.

However, Inpex has the enthusiasm of the new oil company, and Dahua Industrial is not inferior, Su Chenghun said to Nishioka Shigeru indifferently: "You can see, but please don't touch any equipment, don't interfere with the work of the workers." ”

Shigeru Nishioka was a little surprised and said, "Of course." He had expected Sioux City to refuse. After all, being inspected is never a pleasant thing. Not to mention the location of the wellhead.

Lin Yonggui was worried that something would go wrong, so he said in the middle: "Su Dong, you can't lose the confidential work, machinery and equipment." There are also well-mouthed places, so it's better not to let people visit them casually. ”

Su Cheng was an ordinary worry and said with a smile: "There are more things to keep secret in the control room." It's okay, these things can't be stolen just by looking at them. ”

Lin Yonggui's confidence in Sioux City is really incomprehensible. But it's hard to say anything more.

Shigeru Nishioka was in front of him, and Shell, Exxon, and Rosneft also left technicians to look after the equipment. The rest of the people swarmed into the control room.

It's a container-sized board room, filled with all kinds of machines, the most conspicuous of which are the two computers in the middle, which connect and process the information they strive for, including the maturation of polymers and the amount of oil produced.

At this moment, on the monitor in the center, the whole screen is full of green curves and numbers. If you look closely, the left side is marked with time, total liquid production, total oil production, downhole pressure, and on the right side of the curve in the middle, there is hourly liquid production, hourly oil production, water content, and so on.

Although oil production has just started and it is not possible to get an accurate daily production, based on these data, experienced analysts can guess three or five points.

The two most important parameters are water content and liquid yield.

After the use of polymer flooding, the crude oil that was originally hidden in the pores and the crude oil that was deposited as viscous as asphalt will be turned back into lighter liquid crude oil and converged into the larger reservoir, thereby reducing the water content of the reservoir and increasing the liquid production. Specific to the well, there are also fracturing measures, which will make the fluid production increase more and the water content decrease faster.

The old Baku oil block selected by Sioux City is still in production, and the combined water content before treatment is 65%, which is much smaller than the more than 80% that lost value, indicating that it is still profitable and is still being exploited here. However, only 35 tons of crude oil were recovered from 100 tons of liquid, which was almost on the verge of secondary recovery.

For example, the Baku oilfield, which has a water content of 65 percent, is also the chicken rib oilfield that most needs tertiary oil recovery technology in the oil fields of various countries -- it is impossible for European and American companies with deep pockets to maintain a huge contingent of tens of thousands of people like the Chinese oil company, just for the sake of thousands of oil fields with a comprehensive water content of more than 90 percent, and their high labor and equipment will eat up all the profits they have produced, and many companies have even abandoned the wells with a 75 percent water content or adopted intermittent exploitation measures.

BP's technical director, Ducat, who knows a lot about the condition of the oilfield, looked from one end of the screen to the other, and then looked at the other equipment in the control room, quickly grasped the essentials, and then stared at the jumping water content, and said: "How long will it take to measure the accurate water content?"

"In two to three hours, you can have a less accurate water content, and the error value will not deviate too much. ”

"Now it's ...... 62%…… Well, 61 percent, 4 percentage points less than before the injection, isn't that accurate?" Ducatt said to be a tact, if only 4 percentage points down. He felt that it was of little value.

Su Cheng smiled and said: "The water content is calculated according to the separation of the liquid that is fished up, and the computer automatically takes the value, the more you fish, the more accurate it will be." ”

After a pause, he repeated the previous sentence: "In about two hours, the situation in the well will be stabilized, and the value obtained will be relatively close to the average." However, we are not prepared to go to zero. In this case, the value will be different after two hours, and it will be relatively accurate after three hours. ”

"I understand, so to speak, the current more accurate is the amount of liquid produced. ”

"That's right. ”

Ducatt pulled out his notes and looked at them. "The figure I have recorded here, the average daily liquid production before fracturing and polymer flooding is 94 tons, this figure is correct, right?"

Yang Ming immediately checked his notes and replied, "Yes, the average daily liquid production before fracturing was 94 tons. ”

"The average liquid production per hour is 392 tons. "Ducat's leg is wrong, he is on a stick, but his brain is spinning fast. Then he added: "The average liquid production per minute is 00,653 tons, well, it's not accurate to say that, an average of 03,267 tons every 5 minutes." 06,533 tons per 10 minutes on average. Right?"

"A cycle of 3 and a cycle of 6, there is no need to round up. "Dean Qin is even more of an exquisite madman.

Ducatt smiled, looked down at the torture he had just mentioned, and looked up at the monitor. "It's 27 minutes now, and the liquid production is 3,051 tons. Well, equivalent to ......"

"0113 tons per minute, 5 tons per 565 minutes, 678 tons per hour. Qin Shiwei quickly came to a conclusion.

"If we maintain this rate, we can produce ...... per day 163 tons?" Ducater was surprised: "The amount of liquid produced has increased a lot, 73%, this is the effect of fracking, right?"

"That's right, and it's stable. Su Cheng was not surprised by this number, smiled, and said: "As far as our experience is concerned, after the completion of maturation and fracturing, the liquid production will not change much, after all, it is a mechanical lifting operation. The next step is to look at the water content. ”

Ducater nodded slightly, and said: "Even if the water content does not decrease, this liquid production alone can increase the oil production, no wonder you say that the oil production can exceed 50 tons, just a fracturing operation, there is 57 tons of oil production." ”

At this point, he fell into thought.

Qin Shiwei clasped his hands, pinched the bones of his hands, and said with a smile: "You have also tested fracturing operations, how many times have you increased the liquid production by 73%?"

Among the technologies mastered by Dahua Industrial, tertiary oil recovery and fracturing operations are integrated, and there is a special project team responsible for the technical details. This investment in manpower and resources is far greater than that of other companies in the same period.

Ducater suddenly said: "You mean to say that Dahua's fracturing technology increases the amount of liquid produced more?"

"It's not that simple. Qin Shiwei proudly hugged his chest with his arms, and his bulging muscles looked like Mr. Bodybuilder.

"Why is that?" the unpleasant Tokyo accent sounded again, but it was Shigeru Nishioka returning from the wellhead.

Qin Shiwei couldn't get used to Xiao Ri, and sneered: "Didn't you go to check?"

"It seems that there is no problem. Shigeru Nishioka told the truth, and then asked, "Is there anything complicated about Dahua's fracturing technology?"

"That's our business. Qin Shiwei turned his head unceremoniously and ignored him.

Lin Yonggui patted his forehead and thought to himself: I didn't expect Zhang Yuming to do a good job, and he is really an international level metrology expert!

Shigeru Nishioka did not check the problem, and Lin Yonggui undoubtedly attributed it to Zhang Yuming's cheating level, and was silently proud.

"The water content has dropped to 60 percent. Standing in front of the screen at all times was Gilles of Fina, who exclaimed in a French tone: "The water content seems to be declining." ”

For every percentage point drop in water cut, at 163 tons of liquid production, it is equivalent to 163 tons of extra oil production, which is nothing for an oil well, but it is a lot in terms of proportion. At present, the actual combat data of many tertiary oil recovery laboratories is only an increase of two or three 163 tons.

Ducater looked at the time on the screen, it was still less than 30 minutes, and couldn't help but be secretly surprised, the water content dropped so quickly, indicating that the actual water content may be lower...... Perhaps, it can drop to 58%?

If the water content is reduced by 7 percentage points, ordinary tertiary oil recovery laboratories can also make it. BP's own tertiary oil production laboratories have had better than that, but they have had a limited increase in fluid production, no more than 20%, which is a huge difference from the 73% seen so far, so the final data is very different.

Of course, BP, like other large oil companies, is a multi-point investment, for the tertiary oil production laboratory, the annual expenditure will not exceed 10 million, most of the time only about 5 million. Ducater secretly thought: If you look at the data of a 7% decrease in water content and a 73% increase in liquid production, it is not bad to spend tens of millions to buy Dahua's technology, but I don't know how high the content of polymer dry powder is.

Just thinking about it, the French once again popped out a sentence with the tip of their tongue: "The water content is 59%." ”

"So fast!" Ducatt couldn't help but look at the screen, only to see one of the curves, quickly downward, without the slightest intention of bottoming out.

ps: I ate "deboned beef" today. Bone-in boiled beef, cooked very badly, served on a whole plate, eaten with various seasonings. At checkout, simply weigh the plate and bones, minus the weight when serving, which is the weight of the meat, and pay according to the weight of the meat. The real big piece of meat is extremely cool and shows off...... Thanks to the government and the readers, I have lived a life of electric lights and telephones upstairs and Liangshan heroes downstairs.

In other words, if I go to Liangshan, I will probably be made into boneless pork meat by Sun Erniang, what slogan will I shout at that time?

Heroic and slow, can I write a book for you?

Most of the heroes still prefer pork steaks.
