Chapter 353

Chen Xin is not a person who will delay. He and Qin LAN come to the home of "drilling master" directly from the railway station. They plan to ask him for help to drill a deep geothermal well to build an energy tower.

The home of "drilling master" is located at the foot of a mountain in the suburb. Because of its location, the snow here is not so deep, and it has been cleaned up, so that Chen Xin can see that it should be a courtyard similar to a small factory.

It seems that the yard and the factory building have been abandoned, but the snow has been cleared up so that Chen Xin and Qin LAN can enter the yard from the outside and see that the yard is obviously equipped with a protective door.

Behind the protective door should be the refuge of "drilling master". It seems that like Chen Xin, he chose to dig a living space against the mountain, effectively using the mountain as the protective layer of the refuge.

Chen Xin and Qin LAN contact the "drilling expert" through the radio on the power armor, and soon he opens the protective door and appears in front of Chen Xin and Qin LAN.

"I haven't seen you for a long time," he said Chen Xin greets the "drilling expert" and looks at his friend whom he hasn't seen for more than a year.

"Drilling master" is a middle-aged man who is nearly 40 years old. In Chen Xin's memory, he used to be very rich and well maintained. Although he works on the construction site all the year round, like a contractor, he is very generous and kind, and he is the big brother in the survival group.

But now the "drilling master" looks a lot thinner, the whole person is also a lot older, and his black hair has become white. Obviously, it took him more than a year to bear a lot of pressure before he became like this.

However, in spite of this, the forthright and cordial character of "drilling talent" has not changed. He warmly greets Chen Xin: "it's a writer! Long time no see. Welcome! What brings you here? Come on, come in and sit down! "

Then he called Chen Xin and Qin LAN into his refuge.

Although it is similar to Chen Xin's refuge, which is excavated in the mountain, the "drilling master" here is still different from Chen Xin's home. He did not dig a tunnel like Chen Xin to dig the refuge in the mountain, but dug it directly along the mountain wall.

Although the protection ability is slightly poor, the construction difficulty is much smaller and the cost is relatively lower, which is a more economical and applicable method.

After Chen Xin and Qin LAN entered the shelter and sat down, Chen Xin said his intention: "Daren, is your drilling equipment still there? I need you to help me drill a deep well

"Deep well? How deep are you going to drill? " Talking about his own professional field, "drilling master" showed his confidence as a master: "my drilling equipment is still in service, and I can start work after maintenance. It's not my boast. My drilling rig can drill hundreds of meters deep. How deep do you want to drill? Three hundred or five hundred? "

Hearing this, Chen Xin shook his head and said with a smile, "it's not 300, it's not 500, it's 3000. I want to drill a 3000 meter deep well."

"Three thousand meters?! Are you kidding, writer? " Hearing Chen Xin say that he wants to drill a 3000 meter deep well, even if he is called "master", he can't help shaking his head: "if you want me to drill a well of three or five hundred meters, you want me to drill it casually, but 3000 meters I can't do that. "

Chen Xin was not surprised to see that the "drilling expert" said that he could not do it. Instead, he asked him seriously: "what are the reasons why you think you can't do it? Your rig is not good, or your technology is not good? "

"There are two reasons. I haven't drilled that deep, and my rig can't drill that deep." "Drilling master" is very helpless shaking his head, a deep look at Chen Xin, his request is speechless.

However, even so, the "drilling expert" explained to Chen Xin: "although my old Cao called himself" drilling expert ", he was just a man who helped people to drill machine wells. As you know, the local writer of Hunan Province, if he could not drill down 50 meters without water, he was short of water. A few deep wells were drilled in the mountains before, because of the thick soil layer on the mountains A well hundreds of meters deep.

But now you want me to drill a 3000 meter deep well, not to mention that the maximum depth of my drilling rig can only drill 1000 meters. I don't have any experience in drilling such a deep well!

Drilling is nothing else. If you go down and drill directly into the rock formation or something, it's OK to say that if you drill into the water layer or magma or something like that, this well will be abandoned. "

The real name of "drilling expert" is Cao Daren. That's why he gives himself the nickname of "drilling expert". Moreover, because it sounds like a word different from the tiger of serious crime group, he prefers to be called by others.

However, although Cao Daren gave himself the nickname of "expert", he still knew very well that drilling is not to drill anything else. Although as long as the drill bit is hard enough, the drill pipe is long enough, and how deep a well can be drilled out, there are all kinds of problems in the process of drilling. These are not to say that the drill bit is hard enough and hard drilling can solve them.

Blowout, overflow, sticking, lost circulation, collapse Since he began to work in this field in his twenties, Cao Daren has encountered all kinds of problems for more than ten years. He deeply knows that every time the drill moves one meter underground, the possibility of all kinds of problems will increase by one point.A 3000 meter deep well can never be drilled easily.

After hearing what Cao Daren said, Chen Xin thought about it for a while and then said to Cao Daren, "if I can help you solve the problem of drilling rig, can you try to drill a 3000 meter deep well?"

"It's not just about the rig. I've never drilled such a deep well before." Cao Daren smiles bitterly. He is not unwilling to help, but really knows the danger of drilling a 3000 meter deep well.

However, facing Chen Xin's eyes, he thought about it for a while and then replied, "if you can help me get a professional deep well drilling rig, I can try it, but I don't guarantee that I can drill so deep. Besides, I can't do it alone. At least you have to find some helpers for me."

When Chen Xin heard Cao Daren say this, he nodded his head clearly. It seems that it is impossible to drill a deep well directly into the deep stratum to bring out the geothermal energy in the deep stratum, as he thought before.

At present, the most appropriate way is to drill a shallow geothermal well, build the energy tower, and then upgrade the energy tower to deepen the well, so as to exploit deeper geothermal resources.
