Chapter 371: Difficulties

Now that the location for drilling the well has been selected, Cao Daren's drilling rig naturally came in handy again.
He took the workers assigned by Chen Xin to the Seventh Middle School in Linshi, ready to drill the return well, while Chen Xin will continue to complete the installation and commissioning of the heating hub with the remaining workers.
Because the two groups of people have to work separately, Cao Daren's group needs to re-establish a stronghold on the seventh middle school to house their tents.
This also makes the first thing they do after going to the seventh middle school is to dig a hole in the snow.
In the snow cave on the railway station, the space left by Cao Daren and his group of workers after they left was not wasted. Professor Zhang took the members of the geological survey team to live in, and also helped carry out some work on the snow cave. Improvements to make it more comfortable to live in.
For these people who are engaged in geological prospecting in the wild all the year round, the time spent in tents is much longer than the time they live in houses.
Let me tell you that the novel app I'm using recently, [\\mi\\mi\\read\\app\\\\] Android and iPhone support!
Years of trekking through mountains and rivers have long since let these geological scholars lose their literary spirit. On the contrary, they have accumulated a lot of field survival experience. Everyone can be called a master of field survival.
In the opinion of Professor Zhang, the living conditions of the snow cave tents are not much worse than when they were in the wild, and even better in many aspects.
"This is much better than when I first started working! At that time, I was in my twenties. The Maotou boy who had just graduated from school went to Wulingyuan to do surveying and mapping with the geological team. There was no tent at that time. We just built a shack with branches and leaves, and spent a whole month in the wild eating and sleeping!" During lunch, Professor Zhang held a very old aluminum lunch box while eating lunch and told Chen Xin. His experience when he was young: "It's like now, tents, sleeping bags, rain ponchoes, the equipment is too complete! It was amazing that we could have a rubber raincoat at that time."
Listening to the story told by Professor Zhang, Chen Xin was quite moved.
At the age of Professor Zhang, when he was a young man in his twenties, that was the most turbulent era in Yan Country. In that era, he could still endure the difficult conditions to do geological research instead of doing sports. It is very rare.
"Then professor, why do you always use this old lunch box? Now that the weather is so bad, this old-fashioned metal lunch box will soon be cold and it is very inconvenient to use. I'll give you a new lunch box for the professor!" Chen Xin noticed the lunch box in Professor Zhang's hand. Although he didn't know why he used such an old lunch box, Chen Xin still wanted to give him a lunch box that could at least keep warm.
However, Professor Zhang shook his head and smiled and rejected Chen Xin’s kindness: "No, this lunch box has been with me for a lifetime. There is no need to replace this old man when I grow old, and this lunch box is very useful to me. Significance."
Professor Zhang's words made Chen Xin raise his eyebrows, but did not say much about it.
"Professor, how is the distribution of hot dry rock resources in the city?" Chen Xin turned the topic to work and asked him another question that he was most concerned about at this time.
Compared with a heating hub that uses hydrothermal resources, what Chen Xin really wants is an energy tower that can mine deep geothermal resources. After all, an energy tower is stronger than a heating hub in terms of power and efficiency.
But what the energy tower needs is to drill a hole several kilometers underground, not just a few hundred meters deep.
Both the total amount of construction and the technical difficulty are completely different.
"The terrain of the Linshi area is a typical two mountains with a ditch. The terrain is high in the south and low in the north. Although the whole city is east-west, from the overall topography, it is still a north-south geological fracture. The geothermal resources of China are distributed on this fault zone.
While eating, Professor Zhang explained to Chen Xin the topography and geothermal resources of Lin’s city:
On this fault zone, Hunan Province is distributed. The main hot dry rock resource reserves.
Because of the formation of geological faults, it is relatively easy to extract the shallow and middle geothermal heat in this area. Many of them even form hot springs and gush out of the surface. But also because of the occurrence of geological fractures, the geological structure of this area is relatively complicated. If you want to exploit deep geothermal resources, drilling will be a huge challenge. "
Hearing Professor Zhang's words, Chen Xin's heart sank a little.
The implication of Professor Zhang's words is simple, let Chen Xin first concentrate on developing shallow and middle geothermal resources, while deep underground resources think twice.
Chen Xin naturally listened to Professor Zhang’s suggestion, but he did not give up his ideas on the development of deep geothermal resources, but considered more deliberately ~EbookFREE.me~ Even if it is a challenge, now we I have to face it. "Chen Xin's tone was a bit heavy, but he was also very firm. He asked Professor Zhang: "Professor, if we want to exploit deep geothermal resources in the city, what problems do we need to face?" "
"That's too much. First of all, you have to solve the problem of the drilling rig." Professor Zhang put down the rice spoon in his hand and pointed out the biggest difficulty at the moment: "If you want to exploit deep geothermal resources, you must Only a professional drilling rig can do this. Not only does your friend’s drilling rig not only have insufficient drilling depth, but the diameter of the hole is also very limited. The development of shallow and middle geothermal resources like this can still make a living, but if you want to continue to dig deeper, But it's not that simple.
The geological structure of Hunan Province is very complicated. If you drill down, you can hit anything. The rock formations are fine. You can drill slowly. But if you hit other geological formations, it will be very troublesome. If you are not experienced enough, you are afraid It is difficult to deal with various problems that arise during the drilling process. "
"You don't need to worry about the drilling rig, I will solve it." Among the problems pointed out by Professor Zhang, Chen Xin is the least worried about the drilling rig. This can be solved by only one upgrade.
However, the geologically complicated problem mentioned by Professor Zhang cannot be solved by Chen Xin. After all, no matter how he upgrades it, it is nothing more than improving the drill bit and cannot affect the formation itself.
Unless it is said that Chen Xin can produce a giant laser drilling rig or a planetary mining machine to directly cut through the formation for mining, the drilling rig will have to face the contest between the drill bit and different formations.
As for laser drilling rigs and planetary mining machines, this is obviously not something that Chen Xin should consider now. With that spare time, he might as well build a world engine to directly transform the earth's environment.
