Advantages

High drilling efficiency, long drilling tool life, submersible impactor drilling, the medium is air, no flushing media recovery and disposal problems, reducing the auxiliary time.
Low cost of use, the submersible impactor requires small shaft pressure and low speed of the drilling rig, while the torque is low, so the natural power consumption is small, and the diameter of the drill pipe is relatively thin, easy to install and disassemble, and the service life is long.
Submersible percussion drilling, the hole wall is more complete, there is no pollution from other media, basically can preserve The original formation structure and water permeability can be maintained, which reduces the well washing time and saves costs.
In severe leakage formations and unstable hole wall formations, the submerged percussion can be used to follow the pipe drilling to completely solve the problem of repeated operations.
