We know the underground rock formations, they’re not the same. Some are very soft and a little hard. According to this situation, when we choose a water well drilling rig to drill a well, for different rock layers, to choose the appropriate drilling method, the following we come to make a detailed division of the underground rock layers, and the corresponding drilling method.
Salt flooring: water-soluble flooring, soft. But the drillers are easy to stick to the mud, and the holes drilled are easy to drop the mud lumps and even collapse.
Mud layer, page: water-sensitive floor, the drill is easy to form mud bag, and the hole is also over.
Flowing sand, gravel, loose broken floor: Loose porous floor, easy to leak water and sand.
High pressure oil and gas well floor: underground storage of oil, natural gas, etc., well blowout is easy and the result is serious.
High temperature floor: floor hot wells, ultra-deep wells encountered floor, mud treatment agent is ineffective, floor is unstable.
Due to the complexity of the formation, we must clearly explore it when drilling a well.
I hope the above method can be helpful to those who drill wells, and if you want to know more about the method of water well drilling rig, welcome to consult.
