Chen Xin is not a person who will delay. He and Qin Lan came directly from the train station to the home of the "drilling expert" and planned to ask him to help drill a deep geothermal well for building an energy tower.

The home of "Drilling Master" is located at the foot of a mountain on the outskirts of the city. Due to its location, the snow here is not that deep and has been cleaned up, allowing Chen Xin to see that it should be a courtyard similar to a small factory building.

The yard and factory buildings seemed to have been abandoned, but the snow was still cleaned up so that Chen Xin and Qin Lan could enter the yard from outside and saw that the yard was obviously equipped with protective doors in the back.

Behind the protective door, there should be a refuge for the "drilling expert". It looks like Chen Xin, who chose to dig a living space on the mountain and effectively utilized the mountain as the protective layer of the shelter.

Chen Xin and Qin Lan contacted the "drilling expert" through the radio on the power armor. He soon opened the protective door and appeared in front of Chen Xin and Qin Lan.

"Long time no see, 'expert'." Chen Xin greeted the "drilling expert", while also looking at this friend whom he hadn't seen for almost a year.

"Drilling Master" is a middle-aged man in his forties. In Chen Xin's memory, he was originally a very rich man and well maintained. Although he worked on the construction site all year round and looked like a contractor, he was very generous and friendly, and he was the big brother in the survival group.

But now the "drilling expert" looks much thinner, he has become much older, and his black hair has become gray in his temples. Obviously, he has been under a lot of pressure for more than a year to become like this.

However, despite this, the generous and friendly personality of the "drilling expert" did not change much, and he greeted Chen Xin enthusiastically: "It's a writer! It's been a long time since we've seen you, welcome! What wind has blown you? Come, hurry up and sit in the house!"

As he said that, he called Chen Xin and Qin Lan into his shelter.

Although it is similar to Chen Xin's refuge and is both excavated in the mountain, the "drilling master" is still a little different from the Chen Xin's family. He did not dig a tunnel like Chen Xin and dug the refuge into the mountain, but instead excavated the shelter directly along the mountain wall.

Although this is slightly less protective, it is relatively less difficult to construct and has a relatively lower cost, which is a relatively economical and suitable approach.

After Chen Xin and Qin Lan entered the shelter and sat down, Chen Xin then said his purpose: "'Master', are your drilling equipment still there? I need you to drill a deep well for me."

"Deep well? How deep do you need to drill?" Speaking of his professional field, the "drilling expert" showed his confidence as an expert: "My drilling equipment is still there, and I can start construction after maintenance. It's not that I brag. My drilling rig, a deep well worth hundreds of meters, can you drill? How deep do you need to drill? Three hundred or five hundred?"

Hearing the "drilling expert" say this, Chen Xin shook his head and said with a smile: "It's not three hundred or five hundred, it's three thousand. I want to drill a deep well three thousand meters deep."

"Three thousand meters?! Writer, aren't you kidding?" Hearing Chen Xin say he wanted to drill a deep well three thousand meters deep, even if he calls himself a "master", he couldn't help but shake his head: "You want me to drill a well three hundred and five hundred meters casually, but three thousand meters... this is really unfathomable."

Seeing that the "drilling expert" said he couldn't do it, Chen Xin was not surprised. Instead, he asked him seriously: "What do you think you can't do it? What is the reason for you? Your drilling rig is not good, or your technology is not good?"

"There are two reasons. I have never drilled such a deep well, and my drilling rig can't drill that deep." The "Drilling Expert" shook his head helplessly, looked at Chen Xin deeply, and was speechless at his request.

However, even so, the "drilling expert" explained to Chen Xin: "Although I, Lao Cao, proclaimed myself a 'drilling expert', I am just a helping person to drill wells. You know that drilling 50 meters down without water is considered a lack of water in this place. The few deep wells I used to drill on the mountain, because the soil layer on the mountain was thick and I had only drilled a few deep wells hundreds of meters.

But now you want me to dig a deep well of three thousand meters. Not to mention that my maximum drilling rig can only drill one thousand. I have no experience in the problems that will encounter when drilling such a deep well!

Drilling is not anything else. If you drill down and drill directly into the rock layer, it would be fine. If you drill down into the water layer or magma, the well will be scrapped."

The real name of "Drilling Expert" is Cao Daren, so he gave himself a nickname for expert. Moreover, because it sounds like only one word from the Tiger of the Crime Team, he prefers others to call him nickname.

However, although he gave himself a nickname for expert, Cao Daren is still very self-aware. Drilling is not about drilling other things. Although as long as the drill bit is hard enough and the drill rod is long enough, you can drill out any well, but you will encounter various problems during the drilling process. These do not mean that the drill bit is hard enough and forced drilling can solve it.

Blowout, overflow, jamming, well leakage, well collapse... Since I started working in this industry in my twenties, Cao Daren has encountered various problems in more than ten years. He knew deeply that every time a drill bit advances one meter underground, the possibility of various problems will increase by one point.

A deep well three thousand meters deep cannot be easily drilled out.

After listening to the problem Cao Daren said, Chen Xin thought about it before saying to Cao Daren: "If I can help you solve the problem of the drilling rig, can you try to dig a well three thousand meters deep?"

"This matter is not just a problem with the drilling rig. I have never dug such a deep well!" Cao Daren smiled bitterly. He was not unwilling to help, but he really knew the dangers that could be brought about by drilling a deep well three thousand meters deep.

However, facing Chen Xin's gaze, he still thought about it and replied: "If writer, 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. In addition, I can't do this alone, at least you have to find a few helpers for me."

When Chen Xin heard Cao Daren say this, he nodded in a clear way. It seemed that it was unlikely that he would drill a deep well and go straight to the deep strata, which would lead to the geothermal heat in the deep strata, as he had thought before.

From the current point of view, the most suitable method is to drill a shallow geothermal well first, build the energy tower, and then deepen the well depth by upgrading the energy tower, so that deeper geothermal resources can be mined.
