Research and Implementation of a New Orientation & Incline Instrument Used in Oil and Gas Wells

摘要：

A new type of oil and gas wells orientation & incline system which is constituted of fiber optic gyroscope and MEMS accelerometer has been introduced. And the system scheme、methods of dynamic northseeking and algorithm have been given. By the introduction of low-speed continuous rotation,the adoption of dynamic rotation mode and the using of inertial systems own output signal,the low frequency random drift error of fiber-optic gyro is decreased,and ultimately this instrument can achieve the oil and gas wells geographic north & Incline angle of probe quickly and accurately. The experimental results show that: the systems orientation precise is within ±1 °,and the level precise is within ±0.1 °. Besides,the system has the advantage of having solid structure,stand high temperature,high shock above JOOg,more than 3000h of MTBF,more than 10 years of life expectancy. It is suitable for all-weather field environment,and is the ideal next-generation oil and gas wells orientation & Incline measurement instrument.
