Introduction:

The instrument uses three axis fiber optic gyro and three axis accelerometer which consists of an inertial measurement unit. Using track calculation of well trajectory characteristic by real time solution(inclination, azimuth, tool face angle and No. 1 pole angle), and can be used for drawing, data Display etc.

 

FOG Gyro While Drilling System

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, with characteristics of strong impact resistance, small drift and high precision etc.

 

Characteristics:

● 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 used in the field of drilling


Application:

1、 oil and gas exploitation

● cased hole, well retest

● Open window positioning, downhole directional perforation

● Oil pipe logging

● measurement while drilling

 

2、 coal mining

● Measurement of gas drainage hole in coal seam
