Gyro While Drilling FOG INS
FOG Gyro While Drilling FOG INS (GWD) adopts 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 previous generation of products, under the condition of ensuring the measurement accuracy, it has achieved a smaller volume and a wider range of applications, which is suitable for narrow borehole oil and gas wells. The instrument has no moving parts, and has the characteristics of strong impact resistance, small drift and high precision.
Features
High precision fast continuous attitude and position measurement
It has the function of self seeking, easy to use
High precision, unaffected by magnetic field
Good seismic performance
Long life, high reliability, long calibration period
Real-time uploading and drawing of measurement data through cable
Multi sensor simultaneous complementary redundancy measurement, high reliability
Can be matched with existing logging instruments to achieve a variety of underground parameters and measurements
Inner diameter 38mm, which can be well used in drilling field
Applications
Oil and gas exploitation
Cased hole, well retest
Open window positioning, downhole directional perforation
Oil pipe logging
Measurement while drilling
Coal mining
Measurement of gas drainage hole in coal seam
