TLX65-200D Gyro Consecutive Inclinometer is a combinative consecutive inclinometer. It can be used independently in measuring well track, window cutting in sidetrack drilling or connected with other downhole instruments. The instrument can be connected with multi-arm caliper imaging instrument to determine the absolute location of casing damaging.
The instrument is based on inertial navigation technology in aviation field. It takes moving adjustment gyro made by special method with high anti-pound and anti-shock performance and Silicon Flexural Accelerometer as core sensor. It suits for the bad environment in oil field and with high accuracy and reliability. It is a consecutive measurement instrument which can accomplish point measuring and consecutive measuring.
