Chapter 354

Drilling sounds like a very technical job, but in fact it is.

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

It's not easy to drill a well in ancient times. It's totally up to people to go down to the bottom of the well and dig by hand. It takes a lot of time and effort to drill a deep well.

Therefore, before drilling a well, we must choose a good location first, and then we can start drilling.

Although drilling now is much easier than drilling in ancient times with mechanical assistance, the technical content is not reduced at all.

It's OK for an ordinary well with a depth of tens of meters. For modern drilling machines with a depth of tens of meters or hundreds of meters, drilling a well with a depth of tens of meters is only a matter that can be done in a few hours, as long as the geological conditions are not particularly complicated.

But looking for water vein, determining drilling location, analyzing geological structure and so on It doesn't mean digging down anywhere.

Drilling a deep well is even more troublesome. It requires not only professional engineering personnel, but also geological experts to analyze the local geological environment to determine whether drilling will cause geological damage, and then select a relatively easy place to drill and start drilling.

In the process of drilling, we also need to deal with the three high problems from the formation itself, high temperature, high pressure and high ground stress.

These three are also the three major problems that restrict the drilling depth, and they are the great test of drilling technology.

"This is my drill. It's just an ordinary drill. Although it can drill a depth of 700 meters, the drill is also an imported drill I specially bought. It can withstand high temperature and high pressure, but it's impossible for this equipment to drill a deep well. If you want to drill a deep well of several thousand meters, you have to use a large-scale drill for drilling oil." Cao Daren took Chen Xin and Qin LAN to visit the rig he stored in the factory and introduced the rig he owned to them.

Just now Chen Xin had learned about the situation from Cao Daren, so he didn't have any questions about what he said. He just looked at the drill in front of him and said to him, "I can transform your drill so that it can drill to the required depth."

"Rig modification? Writer, do you have the ability? " Cao Daren accidentally raised his eyebrows, but when he saw Chen Xin's power armor, he nodded suspiciously, but he still didn't guarantee: "the drilling rig is just a tool, and the main thing is to solve all kinds of problems that may occur in the drilling process. I haven't done this kind of work. If I try to find out everything from the beginning, I'm afraid it will take less than half a year to finish it, and I can't guarantee a long time The success rate of fixed drilling

Cao Daren has enough say in this matter. He said that he does not guarantee the success of drilling. Although he is modest, he is not sure.

"If there is a high-performance drilling rig, can it increase the confidence of success?" Chen Xin asked Cao Daren uncertainly that with the ability of the system, even if he wanted to drill the moon with a laser drill, it was not impossible. If experience was not enough to ensure success, he would use equipment and technology to make up for it.

Cao Daren didn't doubt him about this. After thinking about it for a while, he said: "if there is a good drilling rig, the success will be more certain. After all, some professional drilling rigs drilling a depth of one or two kilometers are the same as playing, but it is also related to the stratum. If it is to drill into granite, it will be a lot of trouble, just the soil layer, it will be very fast."

"OK, let's do it first. I'll try to transform your rig into a large rig that can drill that deep, and then we'll prepare for drilling." When Chen Xin heard what Cao Daren said, he was relieved.

But Cao Daren suddenly asked: "writer, what do you want to do with such a deep well? If you drill a well for 50 meters, it will be finished. Even if you drill a deep well for three or five hundred meters, the hot spring has already come out! "

The geothermal resources in Linshi are quite rich. Although there are no geothermal hot springs on the surface, there are geothermal hot springs underground. Cao Daren himself dug out the hot springs after more than 100 meters.

"I want to get deep geothermal, so I have to get this deep." Chen Xin explained to Cao Daren why he had to drill a 3000 meter deep well, but he also told Cao Daren that he didn't have to go to the right place at one time: "deep dry hot rock geothermal resources are distributed in the depth of 3000-6km. Only by drilling a well deep enough can we exploit it. However, if you think it's difficult to drill a deep well, we can drill a well several hundred meters first Well, take advantage of the underground hot spring. "

Hunan Province is a province rich in geothermal resources. Most areas of the province are rich in shallow geothermal energy and hydrothermal geothermal resources. Deep dry hot rock resources are also widely distributed. Linshi just belongs to the area with hydrothermal geothermal resources, that is, hot spring resources. The temperature of hot spring is not high.

Therefore, whether Chen Xin plans to drill deep wells or shallow wells, he can exploit geothermal resources, but the geothermal resources mined by deep wells are more abundant, the temperature is higher, and they are more in line with Chen Xin's needs.

Hearing Chen Xin say to drill a well several hundred meters to test water, Cao Daren's worried expression suddenly disappeared, and the whole person seemed relaxed. He said to Chen Xin with a smile: "if it is like this, it will be too simple. I can't guarantee it in other places, but if it is within the scope of the city, I will drill a well, not say 100% hot water, but 80% hot water Chance to give you warm water! ""Yes? In that case, I need to dig a well in the location of Linshi railway station. I need to draw out underground geothermal energy 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 he was so confident, Chen Xin naturally asked him to drill 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, "how can we use geothermal energy to evaporate the snow in the railway station? This Can this really be done? "

"From the theory of physics, it can be done, but only if you help me dig out the well first, and you have to dig into the hot spring." Chen Xin looks at Cao Daren and asks him.

Cao Daren was not confident again, but after hesitating for a while, he nodded and said, "if you can help me improve the drill so that the drill can reach a depth of 1000 meters, I can guarantee you a hot spring!"

"Yes? We'll see. " Chen Xin saw that Cao Daren agreed to come down, and then a smile appeared on his face.
