During the drilling process of water well drilling tools, if high-pressure groundwater is encountered, the water may gush out after damaging the covering stratum, forming a fountain.
Water Well Drilling Tools generally do not have water when they encounter granite stones during drilling, because granite belongs to deep igneous rocks, and there is generally no aquifer unless the groundwater can penetrate into the fault zone. Water layer. Therefore, when drilling, it is necessary to determine what kind of rock is drilled, so as to ensure that the well drilled in the future will have water, and if it is drilled, it will be a dead well. Professional drillers should have these experiences.
