Product Details

ER-Gyro03 Gyro While Drilling FOG INS (GWD)

ER-FIW03 All-attitude FOG Borehole Trajectory Continuous Inclinometer.jpg


FOG Gyro While Drilling FOG INS ( GWD ) uses an inertial measurement unit which consist of three axis fiber optic gyro and three axis accelerometer and applied well trajectory tracking algorithm to calculate well information(inclination, azimuth, tool face angle and No. 1 pole angle), and can be used for drawing, data Display etc.

Compared with the last generation, under the situation of ensuring measurement accuracy, it achieves size and volume more miniaturized, more wide application, suit for narrow borehole oil and gas wells. This instrument without any moving parts, have characteristics of strong impact resistance, small drift and high precision etc.
