In the Chinese headquarters in the makeshift camp, the lights were bright.

Qin Shiwei, Nian Zhongxue, Ran Zi'an and other experts in drilling and oil production looked at the exploration map day and night, constantly comparing various materials sent by the exploration team.

They hadn't slept for two days, but no one thought about it. Because by tomorrow, Dahua Industrial's No. 3 well will be drilled to 2,500 meters. When the time comes, a decision must be made whether to finish drilling or continue drilling, and the drilling team cannot be delayed.

Xinma Group chose to drill to 3,500 meters, which will delay them for about a week, and if the oil layer is indeed within 2,500 meters, Dahua Industrial will undoubtedly have a great advantage.

However, based on the test results of the previous wells, the probability of the oil layer being within 2,500 meters does not seem to be very large. If Dahua Industrial continues to choose Chapter 376 for the spraying method of 2,500 meters, and there is no oil layer within 2,500 meters, no matter how hard it tries, it will fail.

Ran Zi'an and Nian Zhongxue studied for two days, and they couldn't say a single ugly thing.

Drilling to 3,500m seems to be the safest thing to do. However, the technology of Xinma Group and Ito Trading Company is advanced, and the speed will not be much slower than that of the drilling team of China, and it is very likely that the oil will be tested in advance......

Qin Shiwei rubbed his brows and looked at Su Cheng, who closed his eyes and recuperated, wondering if he was asleep.

After waiting for a few seconds, he shook his head with a wry smile and said: "Our first drilling well is too anxious, blame me, if I had drilled to 4,000 meters in strict accordance with the requirements, and then tested the oil with a multi-oil layer, the second well would have been able to do it in my heart." It seems that it is too late to increase the depth of drilling. ”

"With the geology of the Tyumen oil field, it is indeed possible for the oil field to go deep to 2 meters. The trouble now is that we are all exploring in an oil field in Kuwak, and the geological conditions are not much different, and we all start from 3 meters to test the oil, which is easy to be taken by others. ”

When Nian Zhongxue spoke, he also looked at Su Cheng.

Based on the current information, it is indeed difficult for them to give a positive answer.

It takes too many resources to understand the thousands of Chapter 376 oil that is buried deep in the ground. 2D and 3D seismic maps, magnetic and gravity test methods, etc., combined with hundreds of theoretical books, still only estimates.

Even after another seven years, people still can't accurately predict what is going on.

Su Cheng thought silently and did not speak.

His mind is not about technology, but about business.

The goal of racing exploration has always been to attract orders from other Russian oil companies. Therefore, it is necessary to win, and winning beautifully is also an extremely important additional condition.

Xinma Group decided to finish drilling with 3 meters, and after Dahua Industrial hesitated, if it also chose 33 meters, it would not be beautiful to win, and it would be ugly to fail.

Well, the depth increased to 2 meters?

The time it takes is more of one thing, and Sioux City is also not optimistic about this depth.

In his impression, there are very few oil fields in the Tyumen oil fields that are more than 4,000 meters deep, and all his impressions are that his notes from the university played a role. The depths described in the books were very easy to remember: within 10,000 feet.

10,000 feet is exactly 3 meters over, and the end is very memorable.

So, drilling to 3,500 meters was a bad decision in Sioux City's eyes. But 2,500 meters is also not a safe decision. It is also difficult to judge whether 3,000 meters is necessary.

Thinking about it, Su Cheng looked up at Qin Shiwei and asked, "Dean Qin, how is the situation at the end of the second well?"

Qin Shiwei participated in the oil testing of the second well from beginning to end, and with his understanding ability, he should be able to make good suggestions.

Qin Shiwei's expression on the opposite side was a little twisted. The second well tasted a bit of Waterloo to him. In fact, Qin Shiwei's suggestions were somewhat negligent in the entire racing exploration process of the Kuwak oilfield, but this is unavoidable in the process of oilfield development. The more experience, the higher the accuracy of guessing, but it does not mean that you can guess 100% correctly.

A few seconds later, Qin Shiwei adjusted his mood and said: "After the cementing operation of the second well was completed, I immediately presided over the inspection, and all the technical indicators met the requirements, and the quality was qualified after electrical testing. At that time, I was in a very good mood......"

After a pause, he continued, half reminiscing, half reporting: "On the 5th, we started the first perforation, first replacing the mud in the wellbore with clean water. Then, in the case of a clear water kill well, we first shot three thin oil layers from 2,100 meters to 2,400 meters, with a thickness of about 18 meters. After the perforation, there was no show at the wellhead, and even there was a drop, after that, we carried out a fishing trap spray, and in the fished water, we found the smell of oil and oil huā, but after all, we did not see crude oil. From the 7th, we shot further and still did not find ......"

Su Cheng listened to his introduction and nodded slowly. It's not like the oil well is dug in place and the oil is spewed out. Of course, this is true in the early days of onshore oil, and now in offshore oil, which usually represents large oil fields and large oil pressure, but it does not necessarily mean this. The Kuwak field was clearly a small field, possibly even an oil sands field, and the lack of downhole pressure was what they expected. If it weren't for that, the former Soviet Union would not have let it go in the initial survey.

Qin Shiwei's main work in Well 2 is to adopt various methods of inducing and spraying to dredge the oil layer, so that the crude oil has the power to be sprayed.

If there is an industrial flow of more than several tons per day, it is a sign that the well is in the right place and that the field is valuable.

If there is no industrial flow, either the drilling is not in the right place or the field is worthless.

Of course, there is a third possibility, which is that the method of spraying is wrong.

However, Qin Shiwei already has a number of drilling and oil production experts, except for the drilling and oil production research institutes of Daqing Oilfield and Shengli Oilfield, the research institutes of other management bureaus are only weak and not strong, and there are also a few experts in the Central Committee and the University of Petroleum, but the experience is not comparable to that of these administrations. Naturally, many foreign monks outside are of high level, but most of them have more equipment and more auxiliary materials, and since Dahua Industry has no way to provide so much equipment, it is useless to find foreign monks.

For example, Ran Zi'an has not played a big role since exploration, and his future development will be more reflected in research.

Su Cheng was silent for a moment, and said truthfully: "We can't follow the ass of the Xinma Group, even if we win, there is no guarantee that we will get a large number of contracts and orders." It's okay to deepen the well down to 3 meters, but what else can you do?"

Nian Zhongxue frowned imperceptibly, and said: "Drilling to 30 meters, it is only 3 meters more than 2,500 meters, and it is difficult to say whether it can touch the oil layer of visible oil within these 3 meters." ”

He has been working in the research department of a state-owned enterprise for many years, where do he still understand those things in business, and he tends to follow the strategy out of a purely competitive plan.

Qin Shiwei somewhat understood what Su Cheng meant, avoided the depth of the well, and said softly: "The second oil well, in fact, there is still a way that has not been tried. ”

"Huh?"

"Substitute spraying method, use crude oil instead of spraying. However, as a result, the oil layer was polluted, and I did not do it because well No. 2 was still an exploratory well, and there was no oil and gas reaction. "There is a series of sequences for the spraying method, the first is to replace the heavy mud with light mud, if it is not sprayed, then replace it with clean water for light mud, and then use crude oil to replace it with clean water.

Once crude oil is used, the original data in the underground is definitely inaccurate. When Qin Shiwei operated the No. 2 well, he hesitated, and at this time, the situation was urgent, and he couldn't afford to waste an exploratory well.

Su Cheng has a good understanding of the technology of Da Erhua, and said: "It's good to use crude oil to spray, in this way, the No. 3 well will be drilled to 3 meters, if the oil can not be produced, we will use the method of crude oil instead of spraying." ”

"After the replacement spray, if the No. 3 well does not produce oil, it will be wasted. Nian Zhongxue reminded.

Su Cheng nodded and said, "If there is no oil, the exploration cost of our entire oil field will be wasted." Replace the spray with crude oil. ”

Qin Shiwei confirmed Su Cheng's idea, prepared at night, and the next morning, at dawn, he got on a helicopter and went straight there.

At a depth of 3 meters, it will take a day or two to grasp it, and the oil test operation will start in about another day.

Li Zhengfu and the others also paid attention to the movements of Dahua Industrial, and when they heard the sound of the helicopter, Li Zhengfu came out of the warm room, greeted Su Cheng from a distance, and asked with a smile: "Su Dong should have decided the drilling depth, right?

The camping house behind him is very different from before, the wooden villa made of thick logs occupies a corner of the temporary camp, with two floors above and below, with a look of five or six hundred square meters, including all the employees of the Xinma Group. Ito Trading Co., Ltd. also built similar wooden villas, but they were slightly smaller, leaving only Daika Koji and Alixa, which still used the former temporary board houses.

Su Cheng was bent on getting orders, and he didn't have a construction team under him, looking at Li Zhengfu who had just come out of the greenhouse, he pouted and said, "Mr. Li doesn't need to be nervous, we only drilled to 70 meters." You still have a chance of 3 meters. ”

"It should be that Su Dong still has a chance of 3 meters. ”

In the gap between the small confrontation between the two, more people walked out of the room.

Li Zhengfu smiled and said hello a few times, and left with his head down. His nervousness was not inferior to that of Sioux City.

Due to their familiarity with the local geology, both drilling teams were extremely fast.

In just over a week, Dahua Industrial's third exploration shaft reached a depth of 3 meters, and the average daily footage rate exceeded that of Xinma Group.

When they cemented the well, the Norwegian drilling team invited by the Singapore and Malaysia Group was still struggling for 2 meters.

This time, the initiative is once again in the hands of Dahua Industrial.

As long as the No. 3 well can see the industrial flow, it is a complete victory.

May 28th.

Sioux City has been putting a satellite phone in front of him since the morning and waiting for the call.
