Doomsday Bunker Upgrade

The drilling rig had stopped at this time, and several workers were gathering around the drilling rig to pull out the drill rod piece by piece.

At the same time, billowing steam has emerged from the location of the drilling rig below, and the hot spring is constantly spraying water upwards, making the scene cloud and mist around.

Chen Xin and Cao Daren came to the drilling rig and watched the hot water spouting from the wellhead below. Chen Xin asked Cao Daren in surprise, "Have you measured the temperature of the water? How much is the temperature?"

"The water temperature is more than 70 degrees, which is very hot." Cao Daren was also very excited at this time, and while answering Chen Xin, he also introduced the situation: "After the drill bit exceeded 400 degrees before, I had a foreboding that the water would come out today, so pay special attention. After a while, as expected, I ran into a rock formation below, and water began to emerge after the penetration."

Hearing Cao Daren said that the water temperature is more than 70 degrees Celsius, which made Chen Xin very happy. High water temperature means abundant heat energy. This way, the heat that can be provided is also more abundant, which is very good for the heating hub. News.

But looking at the hot spring water that is constantly spewing, Chen Xin also has some concerns, and asked Cao Daren: "Will this water keep spraying? If it keeps spraying, will the later construction have any effect?"

"Don’t worry about this writer. The water pressure is not high. The water is being sprayed now because the aquifer has just been broken. The pressure has a process of release, and there is a drill bit in the drilled casing. The space is relatively small to spray water. Come out, the water won't spray like that after the drill is pulled out, and a cover can be added." Cao Daren understood this very well, and quickly explained it to Chen Xin, dispelling his doubts.

At this time, the scientific researchers also knew the news of drilling out of the hot spring and rushed over. Looking at the hot spring water that was continuously pouring, they were excited and asked Chen Xin: "Mr. Chen, I have seen your design drawing, the heating hub. The hot water inside should be circulated? Is it necessary to drill a water injection well?"

Of course, it is impossible to extract geothermal resources by digging a well. Although Hunan Province has abundant groundwater resources, 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, and one well is also drilled into the underground aquifer, which is connected underground with the intake well, and then the intake well is extracted. After the heat is released, the hot water is re-injected into the ground through a water injection well to realize recycling.

"The water injection well must be drilled, but where and how to drill the water injection well, we still need professional guidance. This matter is not in a hurry for the time being." Chen Xin naturally knew that the injection well was going to be drilled, but this matter Not in a hurry.

A water injection well is not like a water intake well, as long as it penetrates into the aquifer and can produce water, it is done.

Because the pumped groundwater needs to be re-injected into the ground to form a cycle with the water intake well, the position of the water injection well must be located in the same aquifer as the water intake well. When positioning, it is necessary to analyze the trend of the aquifer, geology, and the size of the aquifer. Many factors, such as area, water permeability, etc., are not simply done by punching a hole a few hundred meters away.

This is one of the reasons why Chen Xin said that geologists are needed to help. This kind of professional analysis really requires real professionals.

Chen Xin was discussing with the scientific researchers about drilling the water injection well, while Cao Daren was more concerned about construction issues.

Seeing that a section of the drill pipe has been pumped up from the ground, the hot spring water is still gushing out, and it will not stop for a while. While Cao Daren asked the workers to continue the construction, he asked Chen Xin: "Writer, now that the well has been punched out, what do you think will happen next?"

"Next..." Chen Xin habitually raised his hand to touch his chin, but finally touched his face mask with his hand. He had no choice but to put it down before speaking, "Next, wait until the water stops spraying. Let the workers clear up the snow around the well and prepare to start erecting. You don’t have to clean up too much. You can see the ground by digging around the derrick, so you can just lay the foundation later."

The book kiosks that book friends used before have been hung up, and now they basically use \\mi\\mi\\ to read\\app\\\\.

"Are you going to start building a heating hub?" When the researchers on the side heard Chen Xin say this, they immediately understood what Chen Xin wanted to do next.

Chen Xin nodded and replied affirmatively: "Yes, clear the snow, lay the foundation of the heating hub, and set up the scaffolding for construction. After that, I only need to install the parts I have made. Just fine."

After learning about Chen Xin’s arrangement, the researchers and Cao Daren did not raise any objections, but Cao Daren still raised a question to Chen Xin: "Writer, after you build this heating hub, it will be used to melt snow. Right? Then there will definitely be a lot of stagnant water here, plus there is no water injection well now~www.ltnovel.com~ This water intake well will definitely have to pump water by then, and the discharge of this water is also a problem, right?"

"As for the discharge of the pumped water, you don’t need to worry about it. I will wait for the water injection well to be drilled and the whole equipment can be cyclically operated before starting it. Now I will test the machine at most. In that case, it does not matter if it is discharged directly "Chen Xin naturally also considered this kind of thing, and didn't plan to drain the water everywhere.

However, the drainage after the snow melted by Cao Daren mentioned is indeed a problem that needs attention. They dig wells to build the heating hub in the square in front of the Linshi Railway Station, but it is limited by the size of the railway station. In addition, the purpose is to clear the snow in the railway station. When the heating hub starts, the snow melts. The most likely thing is to flow along the gully where the rails are located. It is likely to freeze the rail at that time.

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

So drainage is something that must be considered.

"On the issue of drainage...how about pumping it away with a water pump, and then discharging it to other places?" Cao Daren's idea is simpler, and of course it is more practical: "Anyway, it will freeze immediately when it is discharged directly from the ice and snow. What's too much influence."

Upon hearing Cao Daren's thoughts, Chen Xin and the researchers felt that this method was feasible, but they always felt that something was wrong.

The scientific researcher thought for a while and said, "Isn't it bad for direct emissions like this? According to Mr. Chen, the heating field generated by the heating hub can cover a radius of two hundred meters, and the snow cover is more than ten meters thick. This is already the size of a small lake. If so much water is discharged at will, I am afraid that it is not necessary to freeze an iceberg, I think I can find a way to use it."
