Doomsday Bunker Upgrade

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

The Yan Kingdom has a tradition of drilling wells since ancient times, but in ancient times it was called drilling wells. In addition to the common water wells, there were salt wells, mines, and even natural gas wells.

It is not an easy task to dig a well in ancient times. It is completely time-consuming and labor-intensive to dig a deep well.

Therefore, the location must be selected before drilling the well, and then the drilling of the well can be started.

Although drilling is much easier now with mechanical assistance compared with ancient well drilling, 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 with a depth of tens of meters, as long as it does not encounter particularly complicated geological conditions , it's just something that can be done in a few hours.

But looking for water veins, locating drill holes, 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 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 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's 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, which can withstand high temperature and high pressure. Possibly, if you want to drill a deep well that is several thousand meters deep, you must 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, and asked the two Man described 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 so that it can Drill to the required depth."

"Remodeling a drilling rig? You have the ability as 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: "The drilling rig is just a tool, the main thing is to Solving the various problems that may arise during the drilling process, I have never done this kind of work, and if I were to explore everything from scratch, I am afraid it would 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 kind of matter. He said that although there is a certain modest element to 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, if you don't have enough experience Guaranteed success, then make up for it with equipment and technology.

Cao Daren did not doubt 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 like playing, but This is also related to the formation, 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 this for now. I'll find a way to transform your drilling rig into a large drilling rig that can drill that deep, and then we'll prepare for drilling." Chen Xin felt relieved when he heard Cao Daren say this.

On the other hand, Cao Daren suddenly asked, "What are you doing, writer, when you drill such a deep well? If you drill a well for 50 meters, you will be done. Even if you drill a deep well, it is only 300 to 500 meters. If you drill so deep, the hot spring will be early. Get out!"

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

"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 told Cao Daren that he didn't need to do it all at once: "The deep dry-hot rock geothermal resources are distributed in At the depth of 3,000 to 6,000 meters deep, only a deep enough well can be drilled for mining. However, if you think it is difficult to drill a deep well, we can also drill a well of several hundred meters first and use it Underground hot springs."

Hunan Province is a province rich in geothermal resources. Most parts of the province have abundant shallow geothermal energy and hydrothermal geothermal resources. The distribution of deep dry hot rock resources is also very wide. Linshi happens to belong to hydrothermal geothermal resources. , that is, the area where the hot spring resources are distributed, but the water temperature of the hot spring is not high.

Therefore, no matter whether Chen Xin intends 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 say to test the water in a well with a depth of several hundred meters, Cao Daren's originally worried expression suddenly disappeared, and the whole person seemed to relax, and smiled at Chen Xin: "If that's the case, then It's too simple, I can't guarantee other places, but if it's within the city limits, I'll dig a well, not to mention 100% hot water, but there is also an 80% chance of giving you warm water!"

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

Hearing Chen Xin's words, Cao Daren almost dropped his eyeballs to the ground in surprise. He looked at Chen Xin in surprise and asked uncertainly, "Using geothermal heat to evaporate the snow at 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 help me dig the well first, and you must dig to the hot spring." Chen Xin looked at Cao Daren and made a request to him.

Cao Daren was a little less confident now, but after hesitating for a while, he nodded and said, "If you, writer, can help me improve the drilling rig so that it can reach a depth of 1,000 meters, I can guarantee that I will give you a hot spring. !"

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

There will be four shifts today, let me take a bath and rest, and warm my brain
