Reborn as an oil tycoon

Chapter 15
Regarding the words of the old expert Mr. Zhong, Liu Shang smiled confidently, "Mr. Zhong, just ask."

"Actually, in order to prove that I am worthy of this position as soon as possible, I would like your question to be more difficult."

Hearing what Liu Shang said, the managers in the meeting room, especially those young and middle-aged, couldn't help showing mocking expressions and smiles.

Just kidding, Mr. Zhong in front of you is a very well-known old expert in the oil field. He was once one of the eight kings who were famous in the Fengcheng oil field.

Not to mention you, a freshman freshman, even those present who have more than ten years of experience, dare not say that they understand Mr. Zhong's question by heart? !

"Haha, you kid, you really look a bit like me when I was young."

"Okay, let me tell you what you want, and I will ask you some difficult questions in actual field application."

"Liu Shang, you also said just now that the water injection well profile control technology is to inject various types of plugging agents downhole, so as to adjust the water absorption profile of the water well."

"However, in the current academic field, there are probably two opinions on the adjustment of the water absorption profile of water injection wells."

"One is what Professor Xu supports, using chemical methods to adjust the water absorption profile of water injection wells."

"Secondly, people like us who are engaged in engineering technology, we mainly adjust the water absorption profile through the water injection process and the water separation process."

"I don't know what you think?"

Without thinking or hesitation, Liu Shang said with great certainty: "Mr. Zhong, as I said before, the root cause of the contradiction lies in the formation of water channeling channels, high water-absorbing layers, and water-flooding efficiency during the long-term water flooding development process. significantly reduced, leading to a series of subsequent problems."

"Theoretically speaking, through layered water injection, the use of water distributors to artificially control the amount of water injected into each layer can achieve certain effects and effects."

"However, this method treats the symptoms rather than the root cause. At best, it can alleviate this contradiction, and its effect is very limited."

"For example, most of us currently use two-stage water injection and three-stage water injection. Even if the water injection volume of a single layer is artificially changed, when the injected water enters the formation, there will still be channels for water channeling."

"Mechanical means can't solve the problems and contradictions inside the reservoir at all."

"What's more, there are still many interference factors and difficulties in mechanical dispensing, such as tool failure and unclear card layers."

"So I think that chemical profile control technology will be the mainstream development direction in the future."

Following Liu Shang's answer to this question, the old professor Xu Tiande's eyes became brighter and brighter. He did not expect that this child really gave him a surprise today.

Mr. Zhong, who was born in the engineering department, was not angry because Liu Shang overturned the identification of his group of engineers. On the contrary, like Xu Tiande, the more he looked at Liu Shang, the more pleasing he was.

Obviously, in his heart, he has already realized the key to this issue, and his views are consistent with what Liu Shang expressed.

Old experts like them who have retired and achieved fame, their biggest hobby at this stage is to love talent!
I also hope to find a qualified apprentice so that I can pass on my mantle.

And the young and strong faction of those companies, after hearing Liu Shang's answer, couldn't help but groaned in their hearts.

Although Liu Shang's answer is good, but it's still just a theory, a trick.

At this moment, it is obvious that Liu Shang has attracted the great interest of Mr. Zhong.

"Okay, okay, okay, Liu Shang, you answered well."

"In terms of problem solving, the chemical profile control process is an effective technical means."

"It's rare for you to have such knowledge and insights just as a freshman."

"In the original plan, we are going to discuss a technical issue today, that is, if the profile control of the water injection well is performed, then the mechanical water distributor in the well needs to be taken out in advance."

"But after the profile control measures are over, is there any need to put the water distributor back in again?"

"You have to know that if it is launched again, it will increase the construction cost, and may affect the effect of profile control measures, and even cause a series of subsequent risks."

In fact, this issue has been discussed many times at the technical level of Huahai Company, and a consensus has been reached, that is, after the construction of the profile control measures, there is no need to re-operate the water distributor.

Even Xu Tiande and Mr. Zhong think so.

However, to everyone's surprise, Liu Shang still directly gave his answer without any thought or hesitation.

"Mr. Zhong, don't even think about it. After the profile control measures are implemented, it is very necessary to re-invest the water distributor."

Upon hearing Liu Shang's answer, the young and strong faction in the conference room couldn't help but smile knowingly, sarcastically in their hearts: Heh, this brat is still young!

Even Professor Xu and Mr. Zhong agreed, but you are so sure that it is necessary? !
Could it be that two veteran experts at the top level and our group are not as good as you, a freshman?

Not only them, after Liu Shang gave such an affirmative answer, Xu Tiande and Mr. Zhong all looked serious and looked up at Liu Shang.

"Oh? Liu Shang, since you're so sure, let me hear your opinion."

Liu Shang nodded, and then looked at Xu Tiande, "Professor Xu, let me ask, what is the current profile control and plugging agent system of our company mainly based on?"

Xu Tiande: "Our current plugging agent system in Huahai is mainly based on polyacrylamide gel plus physical plugging expansion particles."

"Professor Xu, what is the molecular weight of the polymer currently used by our company, and what type of cross-linking agent is it?"

Upon hearing the question Liu Shang asked, Xu Tiande and Mr. Zhong were obviously taken aback. They didn't expect that this child really had something in his heart!
Generally, non-professionals will never ask such questions.

Despite being shocked, Xu Tiande still gave the answer truthfully, "The molecular weight of the polymer used by our company is about 800 million, and the crosslinking agent is mainly metal ions."

Liu Shang nodded, "Professor Xu, if my guess is correct, the stability of this polymer gel system in the laboratory will not exceed one and a half years."

"In the real underground environment, considering the temperature, salinity, formation sensitivity, and oil pollution and impurities in the subsequent injection water, its effectiveness will not exceed half a year, or even shorter."

"The possibility of two consecutive profile control measures for a water injection well is very small, so it is obvious that in order to ensure the effect of the measures, it is necessary to put in the water distributor again."
