bushing defect positioning

The TLX Series FOG (fiber-optic gyro inclinometers) Based Wellbore Continuous Surveying System is a wellbore track measurement system of high precision and reliability developed by the company relying on its advantages in aerospace technologies in combination with military navigation technologies. It takes small double-axle FOG and flexible quartz accelerometer as the core parts and can be mainly used for bushing well re-measurement, bushing defect positioning and some other applications. It forms a whole system and can be used conveniently and simply. It is technologically leading in China and many technical specifications of the system have reached the international advanced level in similar products. Up to now, this system has been applied successfully in many oil fields.
