Chapter 554 Green Curve

"It's time to begin." Sha Mingyin habitually shouted, pressed the opening button with his thumb, and opened the valve deep in the oil well. Under the action of the pumping unit, the oil began to flow out.

The staff monitored each detector and valve. On the computer in the control room, the curve of crude oil extraction is gradually rising. This is the most advanced pumping system at this time. Dahua Industry could not completely control it, but adopted the method of import cooperation. The three participating companies are from the Netherlands, France and the United Kingdom. They are all small and medium-sized companies with certain patents and technical strength. Like Chinese suppliers, these three companies have also been strictly contracted into the supply chain of Dahua Strategic Department.

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

Controlling small and medium-sized upstream and downstream companies is the inevitable process of almost every baby elephant to giant elephant.

Withor to the scale and control of the baby elephant, it would be completely impossible for Dahua Industry to touch the huge oil area of Azerbaijan. Compared with the Setan oilfield, just like the difference between a mouse and a mouse nest, even the oil area of Daqing Oilfield, which has been produced for half a century and still maintains production, is difficult to compare with the Aqijiu oil area in the Caspian region.

For this day, Sucheng has been fully prepared for several years.

The three-time oil recovery technology is one of the results of preparation.

Su Cheng looked at the ups and downs of the pumping machine and said confidently, "Let's wait in the control room. It's warmer there, and we can also drink some black tea."

"Chinese black tea is a good thing. You must taste it." Ducat, the technical director of BP, has long wanted to take a look in the control room and responded as soon as possible.

Shigeru Nishioka from Japan's Inpex said in a distrustful tone, "Do you have to go to the control room? If possible, I want to check it at the mouth of the well.

His English is the standard Tokyo accent, which is famous for its unpleasantness, and the word "check" is particularly heavy.

Wang Guan looked at the Japanese with a bad face and immediately said in Su Cheng's ear, "This is the technical specialist of Japan International Petroleum Development Co., Ltd., which is a little famous in Central Asia."

He stayed in Kazakhstan for more than a year, which was half a translator and half a local identity. He was worried that Sucheng did not know the origin of INPEX, so he continued to whisper: "Although INPEX started late, it has been operating in Central Asia for a period of time and has also won a small oil field in Russia. . According to the analysis of the Information Bureau, INPEX has invested a lot in the Caspian Sea region and is an opponent.

Of course, Sucheng knows INPEX, which is one of the nine giants that once won the Azijiu oil field, and it is the only Japanese company that won the Azijiu oil field that year. As a young oil company, it is full of momentum, much like Dahua Industry... Or, it is more like an extended version of Dahua Industry.

However, INPEX has the enthusiasm of a new oil company, and Dahua Industry is not inferior. Su Cheng said to Xigang Mao carelessly, "Whatever look, but please don't touch any equipment and don't interfere with the work of workers."

Shigeru Nishioka said "of course" in a little surprise. He originally thought that Su Cheng would refuse. After all, being inspected is not a comfortable thing, not to mention the location of the wellhead.

Lin Yonggui was worried about something wrong and said in Chinese, "Sou Dong, you can't lose the confidential work. Mechanical equipment, and well as wells, it's better not to let people visit them casually."

Su Cheng thought he 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 by looking at them.

Lin Yonggui's confidence in Su Cheng is really difficult to understand, but it's hard to say anything more.

Shigeru Nishioka was in the front, Shell, Exxon and Rosneft also left technicians to see the equipment, and the rest of the people entered the control room.

This is a container-sized board room, which is full of all kinds of machines. The most conspicuous are the two computers in the middle, which are connected to process the information, including not only the maturing of the polymer, but also the amount of oil produced.

At this moment, on the monitor in the center, the full screen is full of green curves and numbers. Look carefully, the time, total liquid production, total oil production, underground pressure are marked on the left side. On the right side of the curve in the middle is hourly liquid production, hourly oil production, water content, etc.

Although we can't get accurate daily output at the beginning of oil production, according to these data, experienced analysts can also guess three or five points.

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

After the use of polymer drive, the crude oil originally hidden in the pores and the deposited crude oil as viscous as asphalt will turn into lighter ** crude oil and converge into large reservoirs, thus reducing the water content of the reservoir and increasing the amount of fluid production. Specifically, when it comes to the oil well, there are also fracting measures, which will increase the amount of liquid production more and reduce the water content faster.

The old Baku oil block selected by Sucheng is still in production, and the comprehensive water content before treatment is 65, which is much smaller than the lost value of more than 80, which shows that it is still profitable and the reason why it is still being exploited here. However, the extraction of 100 tons of ** is only 35 tons of crude oil, almost to the edge of secondary oil recovery.

For example, the Baku oilfield, which has a water content of 65, is also the chicken rib oilfield that needs the most three oil production technology in the oil fields of various countries - the rich European and American companies, it is impossible to maintain a huge team of tens of thousands of people like PetroChina, just for thousands of oilfields with a comprehensive water content The cost of labor and equipment will consume the profits extracted, and many companies even give up oil wells with 75 water content, or take intermittent mining measures.

Ducat, the technical director of BP, was very knowledgeable about the condition of the oil field. He saw the other from one end of the screen, then looked at the other equipment in the control room, quickly mastered the essentials, and then stared at the constantly jumping water content and said, "How long will it take to measure the accurate water content?"

"Two to three hours, you can have an inaccurate water content, and the error value will not deviate too much."

"Now it's...62... Well, it's 61, 4 percentage points less than before the injection. Is this inaccurate?" What Ducat said is quite tactful. If it only drops by 4 percentage points, he feels that it is of little value.

Su Cheng smiled and said, "The water content is calculated according to the ** separated from the lifting. The computer automatically takes the value. The more you get, the more accurate it will naturally be."

paused for a moment, and he repeated the previous one: "In about two hours, the situation under the well will stabilize, and the value obtained will be closer to the average. However, we are not going to return to zero, so that the value will be biased after two hours, and it will be relatively accurate after three hours.

"Understand, so to speak, what is more accurate at present is the amount of liquid production."

"That's right."

Ducat took out his notebook and took a look and said, "The figure I recorded here, the average daily liquid production before fracturing and polymer drive was 94 tons. Is this number correct?"

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

"The average output of liquid per hour is 3.92 tons." There is something wrong with Ducat's leg. He is holding a civilized stick, but his brain turns fast, and then he said, "The average amount of liquid produced per minute is 0.0653 tons per minute. Well, it is not accurate. The average is 0.3267 tons per 5 minutes, and the average is 0.6533 tons per 10 minutes. That's right, right?"

"There is no need to round up the cycle of 3 and the cycle of 6. President Qin is even more a fanatic.

Ducat smiled, lowered his head to write down the suffering he had just said, and then looked up at the monitor and said, "It's 27 minutes now, and the amount of liquid production is 3.051 tons. Well, it's equivalent to..."

"0.113 tons per minute, 0.565 tons per 5 minutes, 6.78 tons per hour." Qin Shiwei came to a conclusion quickly.

"If this speed is maintained, the daily output can be...163 tons?" Ducat was surprised and said, "The amount of fluid production has increased a lot, 73. Is this the effect of fracturing?"

"That's right, and it's more stable." Su Cheng was not surprised by this figure. He smiled and said, "From our experience, after the end of maturing and fracturing, the amount of liquid production will not change much. After all, it is a mechanical fishing operation. Next, it depends on the water content.

Ducat nodded slightly and said, "Even if the water content does not decrease, this liquid production alone can increase the oil production. No wonder you said that the oil production can exceed 50 tons. In a fracturing operation alone, there are 57 tons of oil production."

When he said this, he fell into thinking.

Qin Shiwei held his hands, pinched his hand bones, and said with a smile, "Have you also tested the fracturing operation. How many times has the liquid production of 73 been increased?"

In the technology mastered by Dahua Industry, three oil production and fracturing operations are integrated, and there is a special project team responsible for the technical details. This investment in manpower and resources far exceeds that of other companies in the same period.

Ducat suddenly said, "Do you mean that Dahua's fracturing technology increases the amount of liquid production?"

"It's not that simple." Qin Shiwei proudly held his arms around his chest, and the raised muscles were like Mr. Bodybuilding.

"Why is that?" The unpleasant Tokyo accent sounded again, but Shigeru Nishioka came back from Iguchi.

Qin Shiwei didn't like Japan and sneered, "Didn't you go to check?"

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

"This is our business." Qin Shiwei turned his head rudely and ignored him.

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

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

"The water content has dropped to 60." Always standing in front of the screen is Giles of Fina Company. He praised with the unique French tone: "The water content seems to be on the decline."

For every percentage point drop in water content, under 163 tons of liquid production, it is equivalent to 1.63 tons of oil production, which is nothing for an oil well, but it is a lot in proportion. At present, the actual combat data of many three oil production laboratories has only increased by two or three 1.63 tons.

Ducat looked at the time on the screen, and it was still less than 30 minutes. He couldn't help but be surprised. The water content dropped so fast, indicating that the actual water content may be lower... Maybe it can drop to 58?

If the water content is reduced by 7 percentage points, the ordinary tertiary oil recovery laboratory can also make it. BP's three oil production laboratories have obtained better data than this. However, their liquid production has increased significantly, no more than 20 at most, which is a huge difference from the 73 seen so far. As a result, the final data difference is quite different.

Of course, BP, like other large oil companies, has a multi-point investment. For the three oil production laboratories, the annual funding will not exceed 10 million, and most of the time it is only about 5 million. Ducat secretly: According to the data that the water content has decreased by 7 percentage points and the liquid production has increased by 73, it is good to spend tens of millions to buy Dahua's technology, but I don't know how high the cost of polymer dry powder is.

While thinking about it, the Frenchman jumped out again with the tip of his tongue: "The water content is 59."

"It's so fast!" Ducat couldn't help looking at the screen and saw one in the curve, quickly going down, with no intention of hitting the bottom and rebounding.
