The drilling rig had stopped at this time, and several workers were pulling out the drilling rods one by one around the drilling rig.

At the same time, steam has already emerged at the drilling hole below the drilling rig. At a glance, the hot springs are constantly spraying water upwards, causing clouds and mist to surround the scene.

Chen Xin and Cao Daren came to the drilling rig and looked at the wellhead below that was constantly gushing out of hot hot water. Chen Xin asked Cao Daren in surprise: "Have you measured the water temperature? How much is it?"

"The water temperature is over 70 degrees, which is quite hot." Cao Daren was also very excited at this time. He answered to Chen Xin while introducing the situation: "After the drill bit exceeded 400, I had a premonition that it would come out today, so I paid special attention. Sure enough, I encountered a rock layer below, and after it was penetrated, it started to come out."

Chen Xin was very happy to hear Cao Daren say that the water temperature was over 70 degrees. High water temperature meant that the heat energy was abundant, so the heat provided was more abundant, which was very good news for the heating hub.

However, looking at the constant gushing hot spring water, Chen Xin was also a little worried and asked Cao Daren: "Will this water continue to spray? If it keeps spraying, will the later construction have an impact?"

"Don't worry, writer, this water pressure is not high. Now I'm spraying water because the aquifer has just been broken, and the pressure is released. There is also a drill bit in the casing that is driven down. The space is relatively small and water can be sprayed out. After the drill bit is pulled out, the water will not be sprayed like this. Add a lid to block it." Cao Daren was very familiar with this and quickly explained to Chen Xin, dispelling his doubts.

At this time, the researchers also came over to know the news that the hot spring was drilling out. Looking at the hot spring water that was constantly gushing, they were excited and asked Chen Xin: "Mr. Chen, I have seen your design drawing. The hot water inside the heating hub should be circulated, right? Do you also need to dig a water injection well?"

Of course, it is impossible to extract geothermal resources just by digging a well and keeping it pumping. Although the groundwater resources in Hunan Province are rich in stock, it cannot withstand such use.

Under normal circumstances, the utilization of geothermal resources is circulated through two wells. One well is used to extract groundwater to obtain heat, while the other well is also penetrated into the underground aquifer and connects to the water intake well underground. Then, after the heat is released, the hot water extracted from the water intake well is re-injected into the underground through the water intake well to achieve recycling.

"The water injection well must be drilled, but where to dig the water injection well and how to dig it, we still need professional guidance. There is no rush for this matter for the time being." Chen Xin naturally knew that he wanted to dig the water injection well, but this matter was not urgent.

A water injection well is not like a water intake well. As long as it is penetrated into the aquifer, it will be done.

Because the pumped groundwater is re-injected into the ground and forms a circulation with the water intake well, the location of the water intake well must be located in the same aquifer as the water intake well. When positioning, it is also necessary to analyze the trend of the aquifer, geology, size and area of ​​the aquifer, and whether it is permeable. It is not simply to drill a hole a few hundred meters away.

This is also one of the reasons why Chen Xin said that he needed help from geologists. This kind of professional analysis does require real professionals.

Chen Xin was discussing the issue of digging wells with scientific researchers, but Cao Daren, who was standing by, was more concerned about construction issues.

Seeing that the drill pipes had been pumped up from the ground, the hot hot spring water was still pouring out and would not stop for a while. While Cao Daren asked the workers to continue construction, he asked Chen Xin: "Writer, the well has been fired now. What do you think will be done next?"

"Next..." Chen Xin habitually raised his hand and wanted to touch his chin, but his hand touched his mask. He could only put it down helplessly before speaking: "Next, after the water stops spraying, let the workers clear the snow around the well and prepare to start building a frame. There is no need to clean too many places. Dig the derrick around it to see the ground, so that the foundation can be laid after it is convenient."

"Are you preparing to start building a heating hub?" The scientific researchers on the side immediately understood what Chen Xin wanted to do next when they heard Chen Xin say this.

Chen Xin nodded and replied with affirmative answer: "Yes, clear the snow, lay the foundation of the heating hub, and build a scaffolding for construction. Then, you only need to combine the parts I have made to install."

After learning about Chen Xin's arrangement, neither the scientific researchers nor Cao Daren raised any objections. However, Cao Daren still raised a question to Chen Xin: "Writer, after your heating hub is built, it will be used to melt the snow? Then there will definitely be a lot of water here by then. In addition, there is no water injection well now, so this water intake well will definitely be constantly pumping water. The discharge of these water is also a problem, right?"

"You don't have to worry about the issue of the discharge of water pumped 'experts'. I will wait for the well to be well and the entire equipment can be operated in circulation before starting it. Now try to remove the machine at most. That way, it doesn't matter if it is discharged directly." Chen Xin naturally considered this and did not intend to drain the water everywhere.

However, the drainage after the snow melted mentioned by Cao Daren is indeed a matter of attention. The location of their wells to build a heating hub is in the square in front of Linshi Railway Station. However, due to the limited size of the railway station, the purpose of which is to clean up the snow in the railway station. When the heating hub starts, the snow melts. The biggest possibility is to flow along the gully where the railway tracks are located, which may freeze the railway.

This is not a trivial matter. If the rails are frozen, it will cause serious accidents of train derailment.

So drainage is something that must be considered.

"About drainage... How about using a pump to drain it and then discharge it to other places?" Cao Daren's idea is simpler, and of course it is more practical: "Anyway, it's ice and snowy now, and it will freeze instantly when it is discharged directly, and it won't have much impact."

When Chen Xin and the researchers heard Cao Daren's thoughts, they thought this method was feasible, but they always felt something was wrong.
