Analysis on Types and Principles of Water Well Drilling Rig
I have been talking about some knowledge of well-drilling rigs in use and maintenance. Now let DTH drilling rig supplier talk about which types of well drilling rigs are divided into, which parts are composed of, and what are the advantages of each. First of all, the first type of impact water well drilling rig mainly relies on the vertical reciprocating motion of the drilling tool, so that the drill bit impacts the bottom of the well to break the rock layer. Its structure is simple, there is no circulating well washing system, and the removal of cuttings and drilling rigs cannot be performed at the same time, so the efficiency is low. The drilling depth is generally within 250 meters, sometimes up to 500-600 meters. There are 2 main types: ① Punch the cone. Use the weight of the drilling tool to impact the formation. At the lower end of the drill, there are several sharp-angled grasping flaps that can be opened and closed. When the drill moves downward under its own weight, the
