Chapter 253: Deep well and shallow well

　　Drilling sounds like a very technical job, but it is indeed the case.
　　 Yan country has a tradition of drilling since ancient times, but in ancient times it is called drilling wells. In addition to common water wells, there are salt wells, mines, and even natural gas wells.
　　 And wanting to drill a well in ancient times is not an easy task. It is completely dependent on people to go down to the bottom of the well to dig manually. It is very time-consuming and laborious to drill a deep well.
　　 So before drilling a well, you must choose a location before you can start drilling.
　　 Although drilling is much easier with mechanical assistance than ancient well drilling, the technical content has not decreased at all.
Ordinary wells with a depth of several tens of meters are fine. With modern drilling rigs ranging from tens of meters to hundreds of meters, drilling a well with a depth of tens of meters, as long as the geology is not particularly complicated , It's just a matter that can be done in a few hours.
　　 But looking for water veins, determining the location of drilling holes, analyzing geological structures, etc.... It doesn't mean that you just need to find a place to dig down.
　　 Drilling a deep well is even more troublesome. Not only does it require professional engineers, but also requires geologists to analyze the local geological environment to determine whether the drilling will cause geological damage, and then choose a place that is easier to drill and start drilling.
　　In the process of drilling, it is also necessary to deal with the three high problems from the formation itself, high temperature, high pressure and high ground stress.
　　 These three are also three major problems that restrict the drilling depth, and are a huge test of drilling technology.
"This is my drilling rig. It is just an ordinary drilling rig. Although it can drill to a depth of 700 meters, the drill bit is also an imported drill bit that I specially bought. It can withstand high temperature and high pressure. But this equipment wants to drill deep wells. The possible thing is that if you want to drill a deep well that is several kilometers deep, you must use a large drilling rig that uses diamond oil.
Cao Daren took Chen Xin and Qin Lan to visit the drilling rig he had stored in the factory. He introduced the situation of the drilling rig he currently owns.
Just now, Chen Xin had learned about the situation from Cao Daren, so he didn’t have any doubts about what he said. He just looked at the drilling rig in front of him carefully and said to him:
I can transform your drilling rig so that it can Drill to the required depth."
"Rebuild drilling rig? Writer, do you have this ability?" Cao Daren raised his eyebrows unexpectedly, but when he saw Chen Xin's power armor he nodded suspiciously, but still didn't have a package ticket: "Rigs are just tools. I have never done this kind of work to solve the various problems that may arise during the drilling process. If I try to find everything from scratch, I am afraid it will take less than half a year to finish it, and there is no guarantee of success."
　　 Cao Daren has enough say in this kind of thing. Although he said that he does not guarantee the success of the drill, although there is a certain element of humility, it is indeed uncertain.
"If there is a high-performance drilling rig, can it increase the confidence of success?" Chen Xin asked Cao Daren with some uncertainty. With the ability of the system, even if you want a laser drilling rig to drill the moon, it is not impossible. If the experience is not enough To ensure success, use equipment and technology to make up for it.
Cao Daren didn't doubt that he had him. After thinking about it, he said, "If you have a good drilling rig, you have a greater chance of success. After all, some professional drilling rigs are just like playing at a depth of one or two kilometers. This is also related to the formation. If you drill into granite or something, it will be a lot of trouble, but the soil is very fast."
　　 "Okay, let's do that first. I will first think of a way to transform your drilling rig into a large drilling rig that can drill so deep, and then we will prepare for drilling." Chen Xin heard Cao Daren say so and felt relieved.
But Cao Daren suddenly asked: "Writer, what do you want to drill such a deep well? If you drill a water well, it will be done at 50 meters. Even if you drill a deep well, it will be three to five hundred meters. If you drill such a deep well, the hot spring will be early. I got out!"
　　 Linshi’s geothermal resources are still rich. Although there are no geothermal hot springs exposed on the surface, there is indeed a geotropical zone underground. Cao Daren himself dug out the hot springs after hitting more than 100 meters down.
"I want to mine deep geothermal, so I must drill this deep." Chen Xin explained to Cao Daren why he had to drill a three-kilometer deep well, but he also indicated to Cao Daren that it does not need to be in place at once: "The deep dry hot rock geothermal resources are distributed in At the depths of 3,000 to 6,000 meters, only a well deep enough can be exploited. However, if you find it difficult to drill a deep well, we can also drill a well of a few hundred meters first. Underground hot spring."
Hunan Province is a province rich in geothermal resources. Most parts of the province are rich in shallow geothermal energy and hydrothermal geothermal resources, and deep dry hot rock resources are also widely distributed. Linshi happens to belong to hydrothermal geothermal resources. , Which is the area where the hot spring resources are distributed, but the water temperature of the hot spring is not high.
　　 So no matter whether Chen Xin intends to drill deep wells or shallow wells, geothermal resources can be mined, but the geothermal resources mined in deep wells are more abundant, with higher temperatures, and more in line with Chen Xin’s needs.
Hearing that Chen Xin said that he would test the water in a well of a few hundred meters, the worried expression on Cao Daren's face was suddenly gone. UU reading www.uukanshu.com seemed to relax, and smiled at Chen Xin: " If this is the case, it’s too simple. I can’t guarantee anything else, but if it’s within the immediate market, I will dig a well. I won’t say 100% hot water is produced, but there is an 80% chance of giving you. Hit warm water!"
"Really? In that case, a well is being drilled at the Linshi Railway Station. I need to draw out the underground geothermal heat and evaporate the snow in the railway station." Chen Xin was a little surprised at Cao Daren's self-confidence at this time, but since The other party was so confident that Chen Xin naturally followed his wishes and asked him to try a well first.
When Cao Daren heard Chen Xin's words, he almost dropped his eyeballs to the ground. He looked at Chen Xin in amazement, and asked with some uncertainty: "Using geothermal heat to evaporate the snow in the train station? This... this is true. Can it be done?"
　　 "From the theoretical point of view of physics, it can be done, but the premise is that you first help me dig out the well, and you must dig into the hot spring." Chen Xin looked at Cao Daren and asked him.
Cao Daren felt a little lack of confidence now, but after hesitating for a while, he nodded and said, "If the writer can help me improve the drilling rig so that it can reach a depth of one thousand meters, I can guarantee you a hot spring. !"
　　 "Really? Then just wait and see." Chen Xin saw Cao Daren agree, and a smile appeared on his face.
