MEASUREMENT WHILE DRILLING SYSTEM

LUHAI MWD system is equipped with international brand of directional sensor and gamma sensor, use US patented well depth measurement technique and exclusive rotary joint design which make our system outstanding in oil and gas drilling industry. It has the unique structure of dropping prevent system allow the down hole parts can be fishing during sticking.

Measurement Parameters:

● Inclination

● Azimuth

● Gravity Tool Face

● Magnetic Tool Face

● Gravity Sum

● Magnetic Field Sum

● Temperature

● Natural Gamma

● Directional Gamma
