MWD Slim Hole

MWD Slim Hole (Φ1-3/8” & 35mm)


METC Slim Hole MWD is manufactured with a 35mm diameter rotary valve pulser imported from the U.S.A, American standard QDT protocol system, using the company's unique core patented technology small size flexible battery technology.

 

Our Slim Hole MWD can work normally in the 2" inner diameter flexible drilling pipe, and can realize 110 ° / 30M. The horizontal drilling distance is more than 200m, which is especially suitable for remaining oil sidetracking horizontal drilling in the old oil fields.

 

MWD Slim Hole Features

 

35mm pulser is driven by rotary valve motor, and 890mm length is the shortest length in the industry.

 

The probe adopts American QDT protocol, with low power consumption, high precision and flexible centralizer design.

 

Low power consumption, MWD battery can work for 400 hours +,  and the working time with Gamma is 300 hours +.

 

It can realize the deflection of 110 ° / 100 ' and the horizontal well drilling more  than 200 meters.

 

26mm flexible battery core patented technology design to ensure tool safety.

 

The core patented technology of double well incline ensures incline real-time and accurate.

 

The Gamma and azimuth Gamma measuring is optional.
