Drilling motor
Drilling motor(PDM drilling) is a kind of energy conversion device that converts liquid pressure energy into mechanical energy, using mud and clean water as the driving medium and delivering it to the bottom of the hole through the central hole of the drill pipe. During drilling, the screw drilling tool directly drives the core pipe and drill bit connected to the transmission shaft at the bottom of the hole to rotate, and the entire drill pipeThe column is only used as a channel for conveying high-pressure working media and as a rod to support the reverse torque of the drill bit, without rotary motion. Compared with conventional drilling, using screw drilling tools has many advantages, such as a significant reduction in drill pipe wear and high penetration rate. It is the main tool for drilling directional holes and plays a role in the field of drilling.

Compared to traditional rotary table driven drill pipe drilling, Drilling motor have the following advantages:
The input flow of drilling fluid is proportional to the output rotational speed of the screw drilling tool.
There is a linear relationship between the output torque of the screw drilling tool and the pressure drop generated by the drilling fluid through the motor.
The rotary power of the screw drilling tool is used to drive the drill bit and reduce drill rod wear.
Compared with rotary table drilling, screw drilling has a faster rotational speed, which is beneficial to improving the mechanical penetration rate.
It can be combined with a rotary table for drilling, improving rotation speed and drilling efficiency.
Directional control of well depth trajectory can be achieved, making it easier to control borehole direction, and reducing drilling deviation compared to rotary drilling.
