Find Water In Drought Area

- Jul 31, 2019-

In early July, experts from the three academies organized a field survey of Fuxing Village. Judging from the past data and the results of field survey, the water-forming conditions in this area are not ideal. Before that, the village has spent a lot of money to construct two water wells continuously downstream of the mountain stream, and no water source has been found, so the technicians'hearts are heavy. But they did not give up. The working group re-analyzed the data of rock distribution, rock characteristics and tectonic distribution in the region, expecting to find "clues" in the middle.


The formulation of water prospecting scheme requires very professional technology, especially in the geological environment where water forming conditions are not good, it is more necessary to integrate various technical means to determine the location of well drilling. According to the situation of surface survey and data collection, the technical team chooses IP method to sweep the area, to control the structural parts in the area, to find the water-bearing structural parts. After two days of intensive work, the technicians of the joint team take geological, hydrological and geophysical data through the forest and mountain streams in the hot summer. Through comprehensive research and analysis, the drilling position is finally determined, the design hole depth is 280 meters, and the data show that there are 2 to 3 water-bearing structures.


With the increase of drilling depth, everyone began to feel nervous. By the time the depth of the hole reached about 190 meters, the sun had set, and the villagers and the staff of the service team were looking forward to it. According to the design depth, there should be a second tectonic belt at this time, but the debris returning from the orifice has not changed. It is not water-bearing tectonic lithology, and the atmosphere on the spot begins to condense.

The technicians transmitted live video to the back expert group. After repeated research and demonstration by the expert group, it was concluded that the hole depth was not enough and should be tested to continue drilling. With the roar of the drill, it seems to hear the sound of the drill cutting rock strata. When drilling into the hole depth of 215 meters or so, the fine rock powder began to form a mass and wet. Soon, a large number of structural sericite rocks were ejected from the hole mouth, accompanied by a large number of water ejection. Villagers began to cheer, so the beginning of this article appeared.


Drilling is continuing. With the increasing depth of water, the underground structure reflects more and more obvious. According to the calculation, the water output per hour of the well is 20 cubic meters, which is a high-quality well. This means that not only can the problem of drinking water be solved, but also the irrigation of fruit trees can be guaranteed, which saves a lot of water costs.
