Doomsday Bunker Upgrade Chapter 259: Subsequent Arrangement
The drilling rig has stopped at this time, and several workers are surrounding the drilling rig and pulling out the drill pipe piece by piece.
At the same time, steam is already coming out of the drilling position below the drilling rig, and the hot spring is continuously spraying water upwards, making the scene cloudy and foggy.
Chen Xin and Cao Daren came to the drilling rig and saw that the wellhead below was gushing hot water continuously. Chen Xin asked Cao Daren in surprise, "Have you measured the water temperature? What 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 to Chen Xin, he also introduced the situation: "I had a hunch that the water was going to come out today after the drill bit exceeded 400. So I paid special attention, and sure enough, I encountered a rock formation below, and after I penetrated it, water began to come out."
I heard Cao Daren say that the water temperature is more than 70 degrees, which makes Chen Xin very happy. The high water temperature means that the heat energy is abundant, so that the heat that can be provided is also more abundant, which is suitable for the heating hub. A very good news.
However, looking at the continuously spewing hot spring water, Chen Xin also had some concerns, and asked Cao Daren: "Will this water be sprayed all the time? If it is sprayed all the time, will the later construction have any effect?"
"Don’t worry about this writer. The water pressure is not high. The water is being sprayed because the aquifer has just been broken. The pressure has a process of release, and there is a drill bit in the drilled casing, so the space is relatively small. The water can only be sprayed out. After the drill bit is pulled out, the water will not spray like this. It can be blocked by adding a cover." Cao Daren understood this very well, and quickly explained it to Chen Xin and dispelled him. of doubts.
At this time, the researchers also knew the news of drilling out of the hot springs and rushed over. Looking at the hot spring water that was constantly pouring, they were excited and asked Chen Xin: "Mr. Chen, I have seen your design drawings. The hot water inside the heating hub should be circulated, right? Is it necessary to drill a water injection well?"
The extraction of geothermal resources is of course impossible to just drill a well and keep pumping. 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, and is connected with the water intake well underground, and then the water is extracted. After the hot water extracted from the well is released, it is re-injected into the ground through the water injection well to realize recycling.
"The injection well must be drilled, but where and how to drill the injection well, professional guidance is needed. This matter is not urgent for the time being." Chen Xin naturally knew that the injection well was to be drilled, but this Things can't be rushed.
A water injection well is not like a water intake well, as long as it is driven into the aquifer and the water can be produced, it is done.
Because the pumped groundwater is to be re-injected into the ground to form a cycle with the water intake well, the location of the water injection well must be located in the same aquifer as the water intake well. When positioning, the trend, geology, and water content of the aquifer must also be analyzed. There are many factors such as the size and area of the layer, whether it is permeable or not, and it is not simply a matter of drilling a hole a few hundred meters away.
This is also one of the reasons why Chen Xin said that he needs the help of geologists. This kind of professional analysis really needs real professionals.
Chen Xin was discussing with the researchers about the water injection, while Cao Daren was more concerned about the construction.
Seeing that the drill pipe has been pulled up from the ground, the hot hot spring water is still gushing out, and it will not stop for a while. Cao Daren asked the workers to continue the construction, but he was right Chen Xin asked, "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 finally touched his face mask with his hand. He could only helplessly put it down before speaking: After spraying, ask the workers to clear 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 that you can lay the foundation afterwards."
The small book kiosk used by book lovers has been hung up, and now they are basically using mimireadingapp\.
"Are you going to start building a heating hub?" The researchers on the side heard what Chen Xin said and 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. Then only the parts I have made are needed. It's good to have the combination installed."
Understanding 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 Is it snowing? Then there must be a lot of accumulated water here, and there is no water injection well~IndoMTL.com~ This water intake well must be pumping water continuously. Is the discharge of this water also a problem? "
"Regarding the issue of the discharge of the pumped water, don’t worry about the "Master". I will wait for the injection well to be drilled and the entire equipment can be cycled before starting it. Now I will test the machine at most, in that case it will be discharged directly. It doesn't matter." 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 railway station. The volume is not large, and its 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 ravine where the railroad tracks are located, and the railroad will probably freeze at that time.
This is not a trivial matter. If the rails freeze, it will cause a serious accident of train derailment.
So drainage is something that must be considered.
"Regarding the issue of drainage...how about pumping it away with a water pump and discharging it to other places?" Cao Daren's idea is simpler, and of course it's more practical: "Anyway, it's iced and snowy now, and it will freeze instantly when it is discharged directly. It won't make much difference."
Hearing Cao Daren's idea, 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 such a direct emission not so good? According to Mr. Chen, the heating field generated by the heating hub can cover a radius of two hundred meters and cover a dozen meters of snow. To calculate, this is already the size of a small lake. If so much water is discharged at will, I am afraid it will not freeze an iceberg. I think we can find a way to make use of it.”
