Director Shang Ao is a little man with a big face, and after listening to Su Cheng's words, he said expectantly: "Our set of equipment is to be exported?"

"For your own use, you have to export it. Otherwise, our investment for so long will be wasted. ”

Shang Ao was confused and asked urgently: "That means, you want two sets of equipment?"

In their eyes, the equipment for export and domestic use is naturally completely different. Foreigners have money, so they can use good materials and high-cost accessories, and domestic companies are short of money, so they can barely make a living.

Su Cheng continued to shake his head and said, "We need a set of equipment, and we will try to do it well." ”

"What a waste of that. ”

Su Cheng was speechless and said, "Good equipment can increase more production, otherwise why do we spend so much money on research." ”

"It's a little bit to be able to save a little. "Chapter 112 The hard work of Lao Gu is helping by the side. He is 50 years old, has experienced three years of disasters, and the era of the most scarce materials, and has a considerable dedication to frugality.

Su Cheng smiled and said: "Lao Gu, if the dispersion device of the polymer flooding is not done well, the ratio error will be large, the accuracy will be weak, and the 3087 you have worked hard to study will not be a waste." ”

Lao Gu touched his head with his rough hand, and said with a smile: "This standard must be met." ”

Su Cheng then turned his head to look at Yao Zefan.

The leader of the equipment project team smiled reluctantly and asked, "Then our equipment, do you want to tear down and redo it?"

"Not all. Sioux City began to look through the final assembly part of the drawings.

For example, such an important thing as tertiary oil recovery equipment, its parts and components, every petroleum student has to study and take exams repeatedly. It is no exaggeration to take the exam 4 times in 4 years.

If Su Cheng were to make the conveyor in its entirety, it would take several days, and he would have to refer to many blueprints, but if he wanted to describe the advantages and disadvantages of the conveyor and make improvements, he had done this countless times.

It's nothing more than a 5-point short-answer question.

A few crosses, describing the various points of the conveyor, this is what Sioux City is doing now.

While he was reading, he drew the 112th chapter in his notebook in shorthand, and others couldn't understand it.

After a while, Su Cheng raised his head and said, "There are several problems with the polymer flooding equipment imported from abroad, and we must avoid them. The first is to configure the corresponding water supply pressurization equipment, the second is the screw conveyor, and the third is the structure of the valve. If we solve these three problems, we can surpass them in terms of level. ”

Yao Zefan heard him say that he also lay on the drawing and looked at it. After a while, he said with a wry smile: "Director Su sees it accurately, if these three parts can improve the level, the effect can be greatly improved, 20% of it must be there, but these three parts are not easy to solve." ”

"If you can jump by 40%, don't you think it's difficult?"

The principle of polymer flooding is to dissolve the modified polyacrylamide with dispersion equipment, inject it into the oil well, and drive out the oil.

In this process, two goals are to be achieved. The first is to reduce the viscosity of the oil and thus dissociate the oil, and the second is to pressurize the reservoir. In the best case, the oil wells treated by the three oil recovery methods can have a period of self-injection period, which is also the most cost-effective.

Because the polymer rarely changes, the focus of polymer flooding is on the dispersion equipment. The solvent must be dissolved as perfectly as possible according to the design concept, so that it can be fully functional.

This is difficult, and even in the laboratory, it is not possible to accurately configure the solvent.

However, the more precise and continuous the injection of solvent, the better the dissociation in the reservoir. In the 80s, the general tertiary oil recovery could recover 20% of the remaining oil reservoirs, and an increase of 40% was equivalent to an increase of 30%, which meant millions of tons of crude oil.

Yao Zefan looked at the "water supply pressurization equipment", "screw conveyor" and "valve system" again, and said: "If you can really increase it by 40%, you will not lose a lot, but it will be too late." ”

Su Cheng waved his hand and said, "Time is my consideration, you just need to consider the technical issues." He changed his words and commented: "Screw conveyor, this has already been said, let's talk about the booster pump first." Although Zhongyuan Oilfield and Dagang Oilfield bought imported machinery, they used the old domestic L59Z water injection booster pump, which is not good and backward. The previous pump, liquid supply capacity and dispersion and dissolution device can not be fully matched, and the automatic control can not be completed, so a new project team should be set up to tackle key water supply and pressurization equipment. ”

Director Shang smiled bitterly: "Where can we still draw manpower, in the past two years, the pressure from above has been tight, and we have invested all manpower." ”

Looking at Sioux City, the tertiary oil production laboratory with less than 100 people is indeed overloaded, and the researchers cannot squeeze the time.

He nodded and said, "I'll go find someone." Next, yes, and then there was the structural problem of the valve......"

The people in each project team listened, and the pen in their hands did not stop. These are people who have been immersed in the project for several years, and some people have been studying chemical oil recovery for more than 10 years.

Su Cheng is talking about the experience of later generations, from the perspective of time, that is, the advanced technology of the early 90s, which may have appeared in foreign journals, but no one has systematically integrated it.

For example, spiral conveying and high-pressure rubber tube conveying, there is no technical difference, but the latter is better than the former.

After persisting for a period of time, most of the equipment companies that use the former still return to the path of high-pressure rubber pipes until the end of the technology.

These things that can be called empirical talk are exactly what the Chinese researchers need, and Su Cheng spoke smoothly and everyone listened carefully.

Director Shang was surprised by Sioux City's promise.

As the deputy of the research institute, he didn't know how many times he had run to the oilfield headquarters, and sometimes he had to go to Shandong*donghe ministries and commissions to run for money, and he knew the difficulty of getting money, and he didn't dare to make such a bold promise as Sioux City.

The afternoon time flies.

At 6 o'clock, Su Cheng proposed to end, and everyone was still reluctant, so they talked for another hour before letting him go.

Although several small projects, as well as large projects in the equipment department, had to be corrected as a result, no one was to blame.

Designers want to make a flawless product, but most of the time, people don't know where the flaws are.

Sioux City was able to point it out, and pointed to the right place, and everyone was naturally willing to accept it with an open mind.

By the time Sioux City arrived at the institute the next morning, more than half of the researchers had been working for more than two hours.

Yao Zefan was even more bare-eyed, and there were thick black tea leaves on the table.

"Didn't go back?" Su Cheng came to the equipment department first, but saw that the powder delivery system had been changed to a rudimentary shape, and the relevant drawings of the high-pressure rubber tube had been drawn, leaving only the various adjustments of the shock plate to be calculated and then drawn.

Yao Zefan took a sip of tea before he said in a hoarse voice: "You have to catch up with the lost time." ”

Su Cheng was stunned for a moment, this word felt extremely familiar.

Behind him, Yu Jinxing from the same project team responded and said: "Yes, think about our 77 years, 78 years of work, that is called hard work." It's only been 10 years, and we're slackening. I have decided that I will get up two hours early and return an hour late every day, work an extra night shift every week, and eat lunch in the laboratory. ”

Sioux City was sluggish and said, "You guys don't slack off at all......"

"Don't let up yet, hey, Lao Yao, when was the last time you worked overtime on the weekend?"

Yu Jinxing snorted and said, "I heard that foreign research institutes also have to work overtime. The little devil's research institute is especially powerful, they all sleep in the research room, and I will move a seat to cover it another day. ”

"Lao Yu, only young people sleep in the office, and the conditions of the people are good, not damp or noisy, and there are sleeping bags......"

"I'm young, too. "No researcher is easy to serve, like Yu Jinxing and Lao Gu's age, they are all people who can retire at any time, and they do things all by heart, except for reasoning, any coercive measures are useless.

Su Cheng would not persuade people, so he pulled Shang Ao over and said, "Shang Office, the ideological work will be handed over to you, and they can work overtime, but they can't stay up late." If this is done well, I will help you remember a great achievement. You can only succeed, not fail. ”

"Yes. Shang Ao has been warned by the leaders of the hospital several times, how dare he pick on the first thing. He immediately said to Yu Jinxing: "Old Yu, you can't trap me, we have been friends for so many years, and we can't work overtime." ”

"Alas, Director Su ......" Yu Jinxing shouted, and was stopped by Shang Ao.

Su Cheng waved his hand and went to look at the drawing.

This morning, it was still mainly about familiarization. However, due to yesterday's familiarity, the attitude of the researchers has been completely different.

Although it is not like a professor in school, being chased and questioned by students, when Su Cheng asks a certain direction, everyone explains that it has tended to be professional, rather than popular.

This made Su Cheng feel relieved and a little struggling at the same time. After all, he is not a scholar, and in addition to the rough outline, he has no concept of detailed calculation formulas such as "the relationship between plunger diameter and power".

However, everyone only thought that he was cautious and did not care.

It's easy to stay up until noon, and the loud horn of the truck sounded outside the window.

Su Cheng breathed a sigh of relief, broke out of the pile of papers, and shouted, "Come two people, accompany me to unload the car." ”

"Unload what?"

"Gloves. ”

"This is coming?" said the lab mates.

Shang Ao said on the side: "Director Su has emptied the material warehouse, and some of the rubber factories are going to be sold to the sea, and they have also been intercepted, a total of 100 boxes." ”

When I went downstairs as I spoke, I saw the driver condescendingly smoking, and the rear compartment of the car was full of wooden boxes and cardboard boxes.

100 boxes doesn't sound like much, but when you actually see the real thing, you know how huge the number is.

"There are tens of thousands of gloves here, can you use them up?"

"PE gloves are thrown away as you go. The rubber VOTON is solvent and oil resistant, CSM gloves are only a little bit, and then there are fingerless gloves, finger sleeves, cuffs, and bracelets with only fingers...... Gloves with sleeves, gloves resistant to high temperatures and ultra-high temperatures, gloves resistant to low temperatures, electrician's gloves...... There are several sets for each person. Su Cheng pulled the list on the carriage and said: "After the director of the business, I informed everyone that disposable gloves should be used one pair at a time, and they should be processed centrally after use, and the drying oven inside should also be installed, especially for rubber gloves and CSM ......gloves."

Everyone stepped forward and began to carry the boxes.

Lao Gu picked up a box of rubber gloves, his eyes suddenly turned red, don't look around and say: "I've been doing it all my life, so I can use gloves before I retire." I used to touch my daughter with gloves on, for fear of burning her face. ”

As soon as he said this, several researchers in their thirties and children at home were all staggering and couldn't hold the box.

Su Cheng was also stunned for a moment, before buying gloves, he didn't think of this, but subconsciously felt that protective equipment should be added...... At this time, think about it, these chemical researchers, hard work overtime home, hands stained with all kinds of chemical reagents, even if they wash with water over and over again, there will still be a burning feeling, even if they want to hug the child again, how dare it, at best, that is, with an elbow.

If you think about it very much, it is just like Lao Gu said, put on gloves and touch the little faces of children.

A pair of gloves protects not only the hands, but also the family.

Looking up at this three-storey Soviet-style building, the hard work contained in it is no longer just a statement. ！！！
