LH无线随钻测量系统 (wireless MWD system)

LH wireless MWD system

1)Product principle

LH wireless MWD system is to follow the drilling process, measuring the drilling deviation and azimuth, drill pipe, profile and the characteristics of strata. Meanwhile, get the measured data to travel to the surface in real time, so as to correctly guide the drilling equipment. The instrument is on single point inclinometer apparatus, which is the development of modern science and technology and the inevitable trend of oilfield drilling efficiency requirements, has become the indispensable part of the directional well and horizontal well drilling technology.
