"Start." Sha Mingyin yelled habitually, then pressed the open button with his thumb, opened the valve deep in the oil well, and under the action of the pumping unit, the oil began to flow out.

The staff monitors every detector and valve. On the computer in the control room, the curve of crude oil extraction is gradually rising. This is the most advanced oil pumping system at this time. Dahua Industrial cannot completely self-made, but adopts imported way of 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 included in the supply chain of Dahua Strategy Department under strict contracts. among.

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

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

If it weren't for the scale and control of the baby elephant, it would be impossible for Dahua Industrial to get involved in the huge oil region of Azerbaijan.Compared with it, the Setan Oilfield is like the difference between a rat and a rat's nest. Even the Daqing Oilfield, which has been producing continuously for half a century and still maintains production, cannot be compared with the Aqijiu Oilfield in the Caspian Sea. .

For this day, Su Cheng has been fully preparing for several years.

Tertiary oil recovery technology is one of the results of the preparation.

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

"Chinese black tea is a good thing, you must taste it." Dukat, the technical director of bp company, wanted to go to the control room to take a look, and responded immediately.

Shigeru Nishioka from Japan's inpex company said in a very distrustful tone: "Do I have to go to the control room? If possible, I would like to go to the wellhead to check."

His English is a standard Tokyo accent that is known to be ugly. The word "check" is particularly hard to bite.

Wang Guan glanced at the Japanese with a very bad expression, and immediately said in Su Cheng's ear: "This is the technical specialist of Japan International Petroleum Development Corporation, and he is well-known in Central Asia."

He has been in Kazakhstan for more than a year, and he is half a translator and half a local receiver. He is worried that Sioux City will not know the origin of inpex, so he continues to whisper: "Although inpex started relatively late, it is still in Central Asia. It has been in business for a while, and even won a small oil field in Russia. According to the analysis of the Information Bureau, Inpex has invested heavily in the Caspian Sea region. It is an opponent.”

Of course Sioux City knew about Inpex, this company was one of the nine giants that once obtained the Aqijiu Oilfield, and it was the only Japanese company that obtained the Aqijiu Oilfield that year.As a young oil company, it is full of momentum, very similar to Dahua Industrial...or rather.More like an extended version of Dahua Industrial.

However, Inpex has the enthusiasm of a new oil company, and Dahua Industrial is not inferior. Su Cheng said to Shigeru Nishioka indifferently: "Look at it as you like, but please don't touch any equipment, and don't interfere with the work of the workers."

Nishioka Shigeru said "Of course" a little surprised.He originally thought that Su Cheng would refuse.After all, being checked is not always a comfortable thing.Not to mention the location of the wellhead.

Lin Yonggui was worried that something might go wrong, and said in Chinese: "Su Dong, you can't lose the confidentiality work, machinery and equipment. There are also places like wellheads. It's better not to let people visit casually."

Su Cheng thought he was just worried, 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.

With Shigeru Nishioka at the forefront, Shell, Exxon and Rosneft also left technicians to tend the equipment.The rest of the people swarmed into the control room.

This is a prefabricated room the size of a container, filled with various machines, the most conspicuous are the two computers in the middle, which are connected to process the information obtained, including the maturation of polymers and the amount of oil produced.

At this moment, on the monitor in the center, the entire screen is full of green curves and numbers.If you look carefully, the time, total fluid production, total oil production, and downhole pressure are marked on the left, and the hourly fluid production, hourly oil production, water cut, etc. are displayed on the right side of the middle curve.

Although oil production has just started and the exact daily output cannot be obtained, based on these data, experienced analysts can guess a little bit.

The two most important parameters are water cut and fluid production.

After polymer flooding, the crude oil originally hidden in the pores and the viscous crude oil deposited like asphalt will turn into lighter liquid crude oil and gather in the large oil reservoir, thereby increasing the oil content of the reservoir. The water volume decreases and the fluid production increases.Specific to this oil well, there are also fracturing measures, which will increase the liquid production rate and decrease the water content faster.

The old Baku oil block selected by Sioux City is still in production, and the comprehensive water content before treatment is 65%, which is much lower than the 80% or more of the lost value, which shows that it is still profitable, which is why it is still being mined here.However, only 100 tons of crude oil are extracted from 35 tons of liquid, which is almost on the verge of secondary oil recovery.

For example, oil wells with a water content of 65% in the Baku oilfield are also the tasteless oilfields that most need tertiary oil recovery technology in oilfields in various countries. It is impossible for European and American companies with deep pockets to maintain a huge team of tens of thousands of people like China Petroleum Corporation. Only for thousands of oil fields with a combined water cut of more than 90%, their high labor and equipment costs will eat up all the profits from production. Many companies even abandon oil wells with a water cut of 75%, or adopt intermittent production. measure.

Ducat, the technical director of bp, has a deep understanding of the oilfield conditions. He looked from one end of the screen to the other, and then looked at other equipment in the control room. He quickly grasped the essentials, then stared at the constantly jumping water content, said : "How long will it take to measure the accurate water content?"

"Two to three hours, there can be a less accurate water content, and the error value will not deviate too much."

"It's now... 62%... Well, it's 61%, which is 4 percentage points less than before the injection. Is this due to inaccuracy?" Dukat said tactfully, if it only dropped by 4 percentage points.He felt it was of little value.

Su Cheng smiled, and said: "The water content is calculated based on the separation of the liquid that was lifted up. The computer automatically calculates the value. The more you lift, the more accurate it will be naturally."

After a pause, he repeated what he said before: "In about two hours, the situation in the well will stabilize, and the value obtained will be closer to the average value. However, we are not going to return to zero. In this case, two hours The final value will be biased, and it will be relatively accurate after three hours."

"Understood, so to speak, the more accurate one is the amount of fluid produced."

"Yes."

Ducat took out his notebook and took a look.Dao: "The figure I recorded here, the average daily fluid production before fracturing and polymer flooding was 94 tons, is this figure correct?"

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

"The average fluid production per hour is 3.92 tons." Dukat's leg is faulty, and he is leaning on a civilized stick, but his mind is spinning fast.Then he continued: "The average fluid production per minute is 0.0653 tons, um, that's not accurate, it's 5 tons per 0.3267 minutes on average. 10 tons per 0.6533 minutes on average. That's right?"

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

Dukat chuckled, lowered his head to record the suffering he just said, and then looked up at the monitor.Dao: "Now it's 'minutes, and the fluid production is 3.051 tons. Well, it's equivalent to..."

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

"If this speed is maintained, the daily output can reach... 163 tons?" Dukat said in surprise: "The fluid production has increased a lot, up to 73%. Is this the effect of fracturing?"

"That's right, and it's relatively stable." Su Cheng was not surprised by this number, smiled, and said: "From our experience, after the maturation and fracturing are completed, the fluid production volume will not be too large. It has changed, after all, it is a mechanical lifting operation. Next, it depends on the water content."

Ducat nodded slightly, and said: "Even if the water content does not drop, the fluid production alone can increase the oil production. No wonder you said that the oil production can exceed 50 tons. Just one fracturing operation has 57 tons. tons of oil production.”

When he said this, he was lost in thought.

Qin Shiwei clasped his hands together, cracking his bones, and said with a smile, "You guys have also tested the fracturing operation, how many times has the fluid production rate increased 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 far exceeds that of other companies in the same period.

Ducat suddenly said: "You mean, Dahua's fracturing technology increases fluid production?"

"It's not that simple." Qin Shiwei crossed his arms proudly, his bulging muscles looked like a bodybuilder.

"Why is that?" The ugly Tokyo accent sounded again, but it was Shigeru Nishioka who came back from the mouth of the well.

Qin Shiwei couldn't get used to Little Japan, 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?"

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

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

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

"The water content has dropped to 60%." Gilles from Fina Company stood in front of the screen all the time, and he praised in a French-specific tone: "The water content seems to be on the decline."

Every 163% decrease in water content is equivalent to 1.63 tons of oil production at a liquid production rate of 1.63 tons, which is nothing for an oil well, but quite a lot in terms of proportion.At present, the actual combat data of many tertiary oil recovery laboratories only increase two or three [-] tons.

Dukat looked at the time on the screen, and it was still less than 30 minutes. He couldn't help being secretly surprised that the water content dropped so quickly, which meant that the actual water content might be lower... maybe, it could drop to 58%?

A water content drop of 7 percentage points can also be made by ordinary tertiary oil recovery laboratories. BP's own tertiary oil recovery laboratory has obtained better data than this. However, their fluid production has a limited increase, at most no more than 73%, which is a huge difference from the [-]% seen so far. As a result, the final data The difference is quite a lot.

Of course, bp, like other large oil companies, invests in multiple points. For the tertiary oil recovery laboratory, the annual funding will not exceed 500 million, and most of the time it is only about 7 million.Ducat thought to himself: According to the data that the water content dropped by 73 percentage points and the liquid production increased by [-]%, it would be 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. .

Just as he was thinking about it, the Frenchman said again with the tip of his tongue: "The water content is 59%."

"So fast!" Dukat couldn't help looking at the screen, only to see one of the curves, going down quickly, without any intention of bottoming out and rebounding.

ps: I ate "bone-free beef" today.The bone-boiled beef is extremely rotten. It is served on a whole plate and eaten with various seasonings.At the checkout, you only need to weigh the plate and the bones, subtract the weight when the dish was served, and you get the weight of the meat, and you can pay according to the weight of the meat.The real big piece of meat is very cool and shows off...Thanks to the government and readers for allowing me to live the life of a light and telephone upstairs and a hero in Liangshan downstairs.

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

Heroes wait a minute, can I write a book and biography for you?

Most of the good guys still prefer pork chops.
