God-level Big Mine Owner

As soon as Wang Xudong walked over, he saw that the drilling rig that was supposed to be spinning and drilling had stopped, and it seemed that they had really encountered some serious problem. Otherwise, they would not have stopped for no reason, and would definitely continue drilling.

Wang Xudong doesn't know much about oil extraction, and he doesn't need to.

Lei Ziyuan understands. He is not only an expert in oil field planning, but also an authority in the field of oil exploration. As soon as he came over, his expression became serious when he saw the situation.

There is no need to ask these drillers what problems they encountered, but they can tell it at a glance. He walked over, squatted down, and looked carefully.

Those were cuttings, mud and other things drilled out of the wellbore. He picked up some with his hands, looked at them carefully, and even smelled them under his nose.

Lei Ziyuan said slowly: It seems that there is no need to continue drilling. The drilling depth is much shallower than I expected.

Wang Xudong is quite clear why there is no need to continue drilling, because the oil reservoir will be reached after drilling a certain distance. If the oil reservoir is drilled through at this time, it will be a big problem. Under the action of strong well pressure, the oil below will be sprayed out, and it is estimated that it will not be able to be suppressed.

All the oil here was gathered by Wang Xudong using the God-level mine owner system, which was more than 600 million tons, forming a huge oil layer. He also knew the depth of this oil layer. It is deep.

But not everyone is as clear as Wang Xudong. There is an engineer who looks like a technician in the drilling team. He has a different opinion and suggested: Professor Lei, I think it is possible to drill a certain distance. Drill this hole a little deeper.

Lei Ziyuan waved his hand firmly and said: There is no need, if we continue to drill, there will be serious problems, so stop here, we need logging operations in the next step, and then put down the casing.

Don't continue to drill down, you can do logging operations, can you put down the casing?

Many knowledgeable people thought in their hearts, this speed is too fast, could it be that the oil buried here is really shallow, well, it must be the case, Professor Lei is an expert, he will definitely not make a wrong judgment.

Just now, through the drilled rock cuttings, mud and other things, Lei Ziyuan has already judged that the position of the drill bit is not far from the oil reservoir, and the drill can no longer be drilled. The next step is to lower the casing.

Here, by the way, let me talk about the oil extraction process.

After the development of oil extraction from the most primitive manual well digging to rotary drilling, the extraction technology has gradually matured. The current oil drilling and extraction process is roughly as follows.

After the oil and gas field development plan is determined, it enters the development process, which includes two main links of drilling and production. The current Fuchuan Oilfield has just entered the drilling process and is preparing for production.

Before drilling, first determine the drilling position on the ground (that is, the drilling well location), and then lay the foundation for installing the drilling rig at the well location and install the derrick and drilling rig. During drilling operations, relying on the power of the drilling rig to drive the drill pipe and drill bit to rotate, the drill bit breaks down the rock formations encountered one by one, and forms a wellbore (also known as a wellbore). The size of the wellbore is determined by the size of the drill bit.

While the drill bit breaks the rock formation, it injects drilling fluid (commonly known as drilling mud) into the ground through the hollow drill pipe, and brings a large amount of cuttings generated by the drill bit to the ground through the circulating drilling fluid. After the solid control device on the ground removes the cuttings in the drilling fluid, the drilling fluid is driven into the well again through the drilling pump

Drilling fluid passes through the inner hole of the drill pipe to the water hole of the drill bit, and then returns to the ground from the annular space between the well wall and the drill string. The drilling process is the process in which the drill bit breaks the rock and the drilling fluid circulates to continuously carry out cuttings and form a wellbore.

After drilling to the designed depth, a special instrument should be lowered into the wellbore for logging operation, the purpose is to determine the downhole formation lithology and the position of each oil, gas and water layer, and then lower the seamless steel pipe ( Also known as casing), and inject cement slurry into the annular space between the casing and the well wall to fix the casing on the well wall.

The depth of the well has reached the ideal position, and it is unnecessary to continue drilling. The workers started to start the drilling rig and withdraw the drill pipe from the wellbore.

The long drill pipes were pulled out one by one, and after they were all pulled out, what appeared in front of everyone was a dark, vertically downward wellbore.

There is no need for Lei Ziyuan to personally direct, the workers of the drilling team, under the command of several technicians, put professional instruments into the black hole and began to detect the conditions inside the hole, especially oil, gas, The location of the water layer.

All kinds of data were detected one by one. Those technicians looked at Lei Ziyuan with admiration, and thought in their hearts, they are indeed experts. Their eyes are better than professional instruments. If you go down, you will really drill through.

No one wants to see the crude oil underneath being sprayed out at this moment under tremendous pressure, even if it is to be sprayed, if the oil is officially mined.

Prepare the casing, put down the first casing!

The person in charge of this professional drilling team came over and personally directed his workers to start putting down the first casing, which is a stainless steel casing made of super stainless steel.

Lei Ziyuan also noticed it, and said with a smile: Xudong, this is what you call super stainless steel. It's a bit extravagant to use such a material to make a casing.

Wang Xudong said: This kind of material must be of good quality.

Others can't afford such a luxury. If you want to order super stainless steel from Sanlian Special Steel Group, you need to wait in line. Wang Xudong is the real boss of Sanlian Special Steel Group, so there is no problem if he wants some super stainless steel.

Such casings are generally made of carbon steel, while Wang Xudong uses super stainless steel. The quality of such casings is naturally much better, and the corrosion resistance alone is many times stronger than carbon steel casings.

Such a wellbore casing can only be regarded as a small test. The entire oil pipeline from Fuchuan Oilfield to Qingyang Port is all made of super stainless steel. This is why Wang Xudong told Chen Sanlian that thousands of tons of super stainless steel should be prepared.

Prepare several thousand tons first, and process them into oil pipelines with a diameter of 1200 mm. If thousands of tons are not enough, add several thousand tons. The entire oil pipeline, with a total length of 56 kilometers, is all made of super stainless steel.

Generally speaking, the pipes used in oil pipelines are mainly carbon steel pipes, and the biggest problem they face is anti-corrosion. Like Wang Xudong, oil pipelines are made of super stainless steel, so there is basically no corrosion problem.

The first super-stainless steel casing was slowly put into the borehole and lowered slowly, then the second, and the third...

At this time, whether it is Wang Xudong and Zheng Xiaotong, or Liu Yu and Zheng Weiwei, they are all spectators, and they don't need to worry about it. Everything is left to the technicians and drilling workers here.

Like Liu Yu and Zheng Weiwei, they grew up so big, and it was the first time they watched the casing running in the oil well at such a close distance. Take it back and enjoy it slowly when you have time.

The casing is smaller than the diameter of the wellbore, and a reasonable gap is formed between the two, in the annular space between the casing and the well wall.

All the casings were put in, and there was no problem after inspection. The first cement pump truck came and injected cement slurry into the annular space between the casing and the well wall to fix the casing on the well wall. The whole process is basically a full mechanical operation, and the speed is very fast.

There are quite a few people around this drilling well, and they all came here after hearing the news, watching the whole process of casing running and cement paddle injection with relish.

I didn't think about it so fast, I thought it would take several days to drill!

Look, our first borehole is done!

Seeing that the cement paddle has filled the space between the casing and the well wall, and the casing has been firmly fixed, many people are happy. As you know, this is the first formal oil well in this oilfield.

It's still a fountain!

I really want to see the scene where oil is ejected from this wellbore in the future!

This step of work has been completed, only to wait for future oil extraction. When this large oil field is almost built and oil can be extracted, it will be a gushing oil well.

When it is necessary to extract oil, the casing is perforated through professional equipment to penetrate the oil layer below, artificially forming a channel through which downhole crude oil flows into the casing. When the formation pressure of oil and gas is high, it can flow out of the ground by itself. This kind of well is called self-flowing oil well.

Here is the gushing well!

When testing with professional equipment just now, the data showed that this oil well is a self-flowing well. In the future, perforation will be carried out to penetrate the oil layer, and a large amount of crude oil will be ejected.

Well, now, before the time for oil extraction, it is natural not to shoot the well, but to cover it first. No, a few drilling workers lifted the well cover, covered the well, and then put warning signs.

The first oil well has basically been completed, and the drilling of the other wells has not stopped and is still working there. The sound of the drilling rig working can be heard clearly.

The well locations for these wells were all selected by Lei Ziyuan himself, and they were completely in line with his planning and design. The first oil well has basically been drilled, and oil can be produced only after shooting. What about the other few wells.

Lei Ziyuan was going to visit several other wells in person, and Wang Xudong was also included. If there were no accidents, the other wells would be in the same order.

Now, Wang Xudong looks at these wells differently. It seems that they are no longer derricks, but oil wells.

Hey, Brother Dong, look!

Liu Yu had sharp eyes and saw that a drilling well not far away was very lively and surrounded by many people. Wang Xudong also saw it, so he couldn't help but quicken his pace and walked towards it.

Lei Ziyuan also saw it, he was slightly taken aback, but also quickened his pace!

This time something really happened!

……………

The second one is delivered!

The first two updates will be sent, and the code will continue. The third update will be posted at around 9:00 pm to meet everyone.
