Gyro Inclinometer in Wireline Logging Tools

Gyro Inclinometer is a combinative inclinometer. It can be used independently in measuring well track, window cutting in sidetrack drilling or connected with other downhole instruments to used.

1. Introduction 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 is suit for the bad environment in oil field and with high accuracy and reliability. It can accomplish point measuring. 2. Specifications Deviated angle measuring range: 0°~90° Measuring accuracy of deviated angle: ±0.1° Azimuth measuring range: 0°~360° Azimuth measuring accuracy: ±2° (azimuth≥3°) Tool face orientation measuring range: 0°~360° Tool face orientation measuring accuracy: ±2° Working environment temperature: 150℃(4h) Overpressure resistance: 100 MPa
