Downhole mud motor is also named mud motor which is the ideal choice in HDD tasks on conquering complex methane. The drill pipe rotates with the mud motor together on drilling. When course control is required, switch the mother line of bending point of mud motor and probe’s course at twelve to the wanted course, to cease the rotation of the drill pipe and the mud motor housing. The HDD equipment only gives thrust, and the rotor of mud motor is rotating by flow of mud pump and hydraulic energy to travel tri-cone little bit to rotate for directional drilling.
