Introduction

TLX-01A FOG(fiber-optic gyro)inclinometers, based wellbore continuous surveying system is a wellbore routing measurement system. It uses the minitype dual-axe FOG and quartz flexible accelerometers, which as its core sensors were developed independently by ASIT Co., Ltd. This system can accommodate itself to extreme working environments in oil-fields, such as repetition measurement of cased well and well-casing damage location, meanwhile the system maintain high precision and reliability.

TLX-01A FOG System has been granted several patents by the Nation Intelligence Bureau. The system successfully introduced FOG into the petroleum industry and performed continuous measurement of wellbore routing with dual-axe FOG. Technical specifications of the system have reached to the international advanced level in similar products around the world. Up to now, this system has been applied successfully in many oil-fields.


Characteristic

Adoption of full solid-state FOG with long operation life, strong anti-shock and strong anti-vibration.

Automatic north-seeking, full attitude continuous measurement.

High precision, high reliability, measuring results not affected by magnetic environment.
