What is ultra-deep drilling?

Internationally, wells with a depth of more than 4500m are generally defined as deep wells, wells with a depth of more than 6000m are defined as ultra-deep wells, and wells with a depth of more than 9000m are also called ultra-ultra-deep wells.

世界深井钻井技术的发展始于20世纪30年代末，M国于1938年钻成世界上第一口4573m的深井，1949年钻成6255m的超深井。目前，全球能钻4500m以上深井的国家有80多个，其中能钻6000m以上的超深井国家有30多个，我们当然也位列其中。

However, the country with the highest level of deep well drilling technology in the world is still country M.

在M国，平均只需要90天时间就可以完成一口5000m左右的深井，只需110天就可以完成5500m左右的深井，140天完成6000m左右的深井，完成7000m左右的深井也只需7到10个月的时间。

井下复杂情况所占时间约占5％到15％。1989至1993年间美国的深井成功率为42％至46％，其中超深井成功率为22％至23％。

The average single well cost of deep wells in country M is 40% to 50% lower than that in other parts of the world.

The important factor that determines all this is that the core technology of ultra-deep well drilling is the ultra-deep well drilling rig.

当前国际上通用的超深井钻机分为6000米、7000米、8000米、9000米、10000米和15000米多种规格。

As the world leader in deep well drilling technology, country M is also the country with the most advanced and sophisticated deep well drilling rigs. There are currently more than 9000 drilling rigs in the world that drill more than 90 meters, and country M has more than 80 of them alone. Among them, 10000 units can drill more than 8 meters, and one unit can drill to a depth of 1 meters.

In theory, the process of drilling an ultra-deep hole is very simple, just install a rotary drill at the bottom of a drill pipe.By using a powerful engine to drive the drill bit on the drill pipe, it can drill through the formation.

With continuous work like this, the hole will continue to deepen.While drilling, fluid is constantly swirling in and out of the hole to cool the bit and maintain the stability of the hole.When the drill bit is worn out, the worker will replace it with another one, and the hole can be drilled in this way.

While the basic principle is well known, drilling an ultra-deep hole is a very difficult job.

Because when drilling deeper and deeper under the surface, a series of technical problems will be encountered.

The most important problem is the excessively high temperature. On average, every 1000 meters below the surface, the temperature rises by 3°C. In geothermal anomalies, the temperature increases faster with depth.There used to be a well drilled in my country. When the depth reached 5000 meters, the temperature at the bottom of the well was 180°C.Under such high temperature conditions, it is a severe test for drill bits and drill pipes.

Not to mention that as the depth continues to decline, factors such as pressure and tight rock formations will greatly affect drilling.

Who can imagine that the hard steel pipe will be twisted softly like noodles in a pot at home in such an ultra-deep hole?

This is why as the saying goes, it is easy to go to the sky and difficult to enter the earth.

For so many years, human beings have conquered the sky, moved into space, and built a space station more than 300 kilometers away.But it has not been drilled into the ground until now. The deepest exploration well is only 15000 meters, and the most famous Hell's Gate stopped at only 12262 meters.

In short, it is a very difficult and long task to complete this super large project.

Chen Fan understands these issues, and Zhang Yang, as an expert in this field, naturally also understands them.

However, when Chen Fan and Zhang Yang explained, they intentionally did not tell him the specific details of this ultra-deep drilling machine.

After all, Zhang Yang knows how to drill, and if he speaks too thoroughly, it will make the other party suspicious.

And since this project has something to do with Wang Weilong, he will definitely think that it is a project supported by GJ.

Then Zhang Yang will definitely try his best.

After Chen Fan finished talking to the other party, Zhang Yang frowned and asked thoughtfully, "Chen Fan, why are you doing this? It's not really for scientific research, is it?"

Chen Fan shook his head and denied, "Of course not all of them. After all, I invested so much, and I must expect a return." "

Zhang Yang was slightly startled when he heard the words, and then, as if he suddenly thought of something, he opened his eyes wide and asked, "No way, Chen Fan, do you want to use this to get into the Chinese Academy of Sciences?"

Chen Fan was taken aback when he heard the words, and shook his head with a smile, "No, my preliminary idea is to obtain new energy or minerals, these things are valuable."

"Uh! So you still want to make money." Zhang Yang laughed hahaha.

Chen Fan didn't hide the intention of the other party, and admitted frankly: "Well, yes, I am a small boss after all."

"Haha, Brother Chen is really honest!!!!"

……

Chen Fan and Zhang Yang, as the front team, pitched tents in the Gobi and started a life of camping in the wild.

In the past few days, Chen Fan's biggest feeling is that after the modern society has no mobile phone signal, the pace of life will become much more gentle, and people will have the opportunity to feel the passage of time.

Spending the night in the desert is a very boring thing, but Chen Fan felt very comfortable these two days. He didn't have to live in a hotel like staying in the city. He should eat and work as soon as he woke up. He had enough time Enjoy this piece of tranquility.

Chen Fan was lying in the tent, looking at the blue sky and white clouds above his head, and listening to the wind in the desert in the distance, a wonderful thought suddenly came to his mind: If there is a tourist attraction here, it should be pretty good...

Of course, he just thought about it in a flash, how could he have time to engage in tourist attractions now, and besides, he himself is too busy now.

"Huh, it's finally here."

Chen Fan and Zhang Yang looked at the powerful convoy in the distance, dragging thick flying smoke towards them.

The two immediately sat up and took their respective equipment to greet them.

This time the convoy consisted of 12 vehicles, two of which were pulling large excavator equipment, and the remaining 6 vehicles were pulling drill pipes weighing hundreds of kilograms.

Soon, the motorcade came into sight of Chen Fan and Chen Fan. They saw many uniformed staff inside the motorcade, as well as a few men in camouflage uniforms.

Chen Fan and Chen Fan immediately walked towards each other. When they got close, they stopped to say hello to each other and introduced each other.

Chen Fan knew that this group of people were construction workers responsible for exploring this ultra-deep well, and they were all sent by GJ. After all, GJ was also involved in this kind of project.

After the introduction, Chen Fan said to a middle-aged man wearing glasses: "Hello, Director Liu, I'm Chen Fan, and this is Zhang Yang."

Director Liu shook hands with Zhang Yang and said hello.

At night, the simple camp was set up, and the three of Chen Fan also determined the task of this job.

Zhang Yang was in charge of technical guidance and experiment content, Liu Hui was in charge of drilling rig construction and experiment execution, and Chen Fan was mainly responsible for contacting and providing drilling rig drawings.

As a result, a huge experimental project of scientific progress slowly kicked off.
