Doomsday Bunker Upgrade Chapter 253: Deep and shallow wells

Drilling sounds like a very technical job, and it really is.

　　Yan country has a tradition of drilling since ancient times, but in ancient times it was 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 going down to the bottom of the well to dig manually. It is very time-consuming and laborious to drill a deep well.

Therefore, you must select a location before drilling a well, and then you can start drilling a well.

Compared with ancient well drilling, drilling is much easier now with mechanical assistance, but the technical content has not been reduced at all.

Ordinary water wells with a depth of tens of meters are not bad. With modern drilling rigs ranging from tens of meters to hundreds of meters, drilling a water well of tens of meters deep, as long as it does not encounter special geological conditions Complicated situations can only be done in a few hours.

But looking for water veins, locating boreholes, analyzing geological structures, etc... It's not just about finding a place to dig down.

Drilling a deep well is even more troublesome. It requires not only professional engineers, but also a geological expert to analyze the local geological environment to determine whether drilling will cause geological damage, and then choose a place that is easier to drill. 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 in-situ stress.

These three are also the three major problems that restrict the drilling depth, and are a huge test for 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. It is absolutely impossible, if you want to drill a deep well that is several thousand meters deep, you have to use a large drilling rig like diamond oil." Cao Daren took Chen Xin and Qin Lan to visit the drilling rig he stored in the workshop , briefed the two about the rig he currently owns.

Chen Xin had already learned about the situation from Cao Daren just now, so he didn't have any doubts about what he said. He just took a serious look at the drilling rig in front of him and said to him, "I can transform your drilling rig. Allow it to drill to the required depth."

"Reconstructing drilling rigs? Do you have the ability to be a writer?" Cao Daren raised his eyebrows unexpectedly, but he nodded suspiciously when he saw Chen Xin's power armor, but he still didn't promise: "A drilling rig is just a tool, The main thing is to solve the various problems that may arise during the drilling process. I have never done this kind of work. If I were to explore everything from scratch, I am afraid it will take half a year to complete it, and there is no guarantee that the drilling will be successful.”

Cao Daren has enough say in this matter. He said that although there is a certain modest element in the success of the drill, he 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. Experience is not enough to guarantee success, so use equipment and technology to make up for it.

Cao Daren did not doubt that he had him, and after thinking about it, he said: "If there is a good drilling rig, then the chance of success will be greater. After all, some professional drilling rigs can drill to a depth of one or two kilometers just for fun. The same, but it is also related to the stratum. If it is to drill into granite or something, it will be a lot of trouble, but the soil layer will be very fast."

"Okay, let's do it first, I'll find a way to transform your drilling rig into a large drilling rig that can drill that deep, and then we will prepare for drilling." Chen Xin heard Cao Daren say this and put it down. Come to the heart.

Cao Daren suddenly asked, "What do you want to do when you drill such a deep well? If you drill a well for 50 meters, you will be done. The hot springs have come out early!"

The geothermal resources in Linshi are quite rich. Although there are no geothermal hot springs exposed on the surface, there are indeed geothermal tropics underground. Cao Daren himself dug down the hot springs by hitting more than 100 meters down.

"I want to mine deep geothermal, so I have to drill so deep." Chen Xin explained to Cao Daren why he had to drill a 3,000-meter-deep well, but he also indicated to Cao Daren that he did not need to do it all at once: "Deep dry-hot rock geothermal The resources are distributed in the stratum at a depth of 3,000 to 6,000 meters. Only a deep enough well can be drilled. However, if you think it is difficult to drill a deep well, we can also drill a well of several hundred meters first. , take advantage of the underground hot springs."

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 hot dry rock resources are also widely distributed. Type geothermal resources, that is, the area where hot spring resources are distributed, but the water temperature of the hot spring is not high.

Therefore, no matter whether Chen Xin plans to drill deep wells or shallow wells, geothermal resources can be exploited, but the geothermal resources mined in deep wells are more abundant and the temperature is higher, which is more in line with Chen Xin's needs.

　　 Hearing 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 suddenly disappeared~IndoMTL.com~ The whole person seemed to relax, and he smiled at Chen Xin:" If this is the case, it is too simple. I can't guarantee other places, but if it is within the city limits, I will dig a well, not to mention 100% hot water, but there is also an 80% chance for you Get warm water!"

"Really? In that case, a well will be drilled at the location of Linshi Railway Station. I need to draw out the underground geothermal heat to evaporate the snow at 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, Chen Xin naturally followed his wishes and asked him to dig a well first.

When Cao Daren heard Chen Xin's words, he almost dropped his eyes to the ground in surprise. He looked at Chen Xin in disbelief and asked uncertainly, "Using geothermal heat to evaporate the snow in the train station? This... Is this really possible?"

"From the theoretical point of view of physics, it can be done, but the premise is that you help me dig the well first, and you must dig the hot spring." Chen Xin looked at Cao Daren and made a request to him.

　　 Cao Daren is a little lacking in confidence, 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 kilometer, I can promise you Get out of the hot spring!"

"Really? Then we'll have to wait and see." When Chen Xin saw Cao Daren agreed, a smile appeared on his face.
