    The drilling rig has stopped at this time, and several workers are gathering around the drilling rig to pull out the drill pipe piece by piece.

    At the same time, steam was already coming out of the drill hole below the drilling rig, and the hot spring was spraying water upwards, making the scene steaming and foggy.

    Chen Xin and Cao Daren came to the side of the drilling rig and saw that the wellhead below was continuously spouting hot water. Chen Xin asked Cao Daren in surprise: "Have you measured the water temperature? What's the temperature?"

    "The water temperature is more than 70 degrees, which is quite hot." Cao Daren was also very excited at this time. While answering Chen Xin, he also introduced the situation: "After the drill bit exceeded 400, I had a premonition that water would come out today, so I paid special attention to it.  After a moment, it hit the rock formation below, and after it penetrated, water began to flow out.¡±

    Hearing Cao Daren say that the water temperature is more than 70 degrees, Chen Xin was very happy. High water temperature means rich heat energy, which will provide more abundant heat, which is a very good heating hub.  news.

    However, looking at the hot spring water that kept gushing out, Chen Xin was a little worried and asked Cao Daren: "Will this water keep spraying out? If it keeps spraying out, will the later construction be affected?"

    "Writer, don't worry about this. The water pressure here is not high. The reason why water is being sprayed now is because the aquifer has just been broken, and the pressure is going through a release process. Moreover, there is a drill bit in the casing that has been driven down. The space is relatively small so water can be sprayed.  Come out, and when you pull out the drill bit, the water won't spray out like this, and it can be blocked by adding a cover." Cao Daren understood this very well, and quickly explained it to Chen Xin, dispelling his doubts.

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

    Of course, it is impossible to extract geothermal resources by just digging a well and pumping water all the time. 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, while the other well is also driven into the underground aquifer, connected underground with the water well, and then the water well is extracted.  After the hot water releases its heat, it is re-injected into the ground through the water injection well for recycling.

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

    Water injection wells are not like water intake wells. As long as they are drilled into the aquifer and water can be produced, that's it.

    Because the pumped groundwater needs to be re-injected into the ground to form a circulation with the water intake well, the location of the water injection well must be in the same aquifer as the water intake well. When positioning, it is also necessary to analyze the trend, geology, and size of the aquifer.  There are many factors such as area and whether it is water-permeable. It is not just a matter of drilling holes 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 the construction of water injection wells with scientific researchers, but Cao Daren on the side was more concerned about construction issues.

    Seeing that sections of the drill pipe had been pulled up from the ground, the hot hot spring water was still flowing out and would 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 drilled, what do you think we will do next?"

    "Next" Chen Xin habitually raised his hand to touch his chin, but his hand touched his mask. He had no choice but to put it down before he said: "Next, wait until the water stops spraying.  , let the workers clear the snow around the well, and prepare to start erecting the structure. There is no need to clear too much area. Just dig around the well and you can see the ground, so that you can lay the foundation later."

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

    Chen Xin nodded and replied affirmatively: "That's right, clear away the snow, lay the foundation of the heating hub, and set up the scaffolding for construction. After that, I only need to assemble the parts I have made and install them."  That¡¯s good.¡±

    After learning about Chen Xin's arrangement, neither the scientific researchers nor Cao Daren raised any objections, but Cao Daren still raised a question to Chen Xin: "Writer, after your heating hub is built, it will be used to melt snow.  Right? Then there will definitely be a place hereThere is a lot of stagnant water, and there is no water injection well now. This water intake well will definitely have to continuously pump water. The discharge of this water is also a problem, right?  "

    "As for the discharge of the pumped water, 'Master', you don't have to worry. I will wait until the water injection well is drilled and the entire equipment can operate in a cycle before starting it. It is best to test the machine now. In that case, it will be ok to discharge it directly.  ." Chen Xin naturally considered this kind of thing and did not intend to drain the water everywhere.

    However, the drainage after the snow melted that Cao Daren mentioned is indeed an issue that needs attention. The location where they dug a well to build a heating hub is in the square in front of Linshi Railway Station, but it is limited by the size of the railway station.  It is large, and its purpose is to clear the snow at the train station. When the heating hub is activated, the snow will melt and most likely flow along the gully where the rails are located, which may freeze the railway.

    This is no small matter. If the rails freeze, it will cause a serious accident such as train derailment.

    So drainage is something that must be considered.

    "As for the issue of drainage How about pumping it away and then discharging it to other places?" Cao Daren's idea is relatively simple, and of course more practical: "Anyway, it's icy and snowy now, and if it's directly discharged, it will freeze instantly, so there won't be any  What a big impact.¡±

    Hearing Cao Daren¡¯s idea, Chen Xin and the researchers both 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 to emit such direct emissions? According to Mr. Chen, the heating field generated by the heating hub can cover a radius of two hundred meters, calculated based on the snow cover of 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 an iceberg will freeze out. I think we can find a way to use it." (Remember the website address: www.hlnovel.com
