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.

2)Main technical indicators

◎well deviation: ±0.2 o

◎bearing: ±0.5 o

◎Tool face: ±0.3 o (GTF);±0.5 o (MTF)

◎Gamma: ±5API

◎The resistivity: 0.2~1Ω∙m    ±20%; 1~5000Ω∙m    ±10%; 5000~40000Ω∙m   ±20%。

◎Down-well instrument: Working temperature: -30~+125℃ Storage temperature: -40~+150℃

◎Ground-based instruments: Working temperature: -30~+85℃ Storage temperature: -40~+100℃

◎Down-well instrument power battery: 36VDC/25AH

◎The seismic capacity: 1000G 1ms

◎Pressure range: 100Mpa

◎Battery life: Not gamma, more than 400 hours, with gamma: more than 250 hours.

3)Advantage characteristic:

★New design, easy to hook up the other sensors and to upgrade

★Comprehensive protection technology, safety and equipment of high reliability
