[Abstract]:With the rapid development of MEMS (Micro Electrical Mechanical System) in recent years, inertial devices based on MEMS are being widely used in various fields. This topic is based on the background of petroleum exploration and exploitation, and studies the technology of oil well inclinometer based on MEMS inertial devices, development of oil well inclinometer system and the establishment of MEMS gyro error model. And MEMS plus error model, using various models to calibrate the real signal in real time, obtain accurate angular rate signal and acceleration signal, use the acceleration signal to integrate the position of the borehole in the set coordinate system, and use the angle rate signal to obtain the attitude information of the drilling platform. The working principle of the inclinometer mechanism is described in detail, the working principle of the inclinometer mechanism is expounded in detail, the mathematical model of the oil well inclinometer is set up, the solution method of the position matrix and the attitude matrix is given. The working principle of the MEMS accelerometer and the MEMS gyroscope sensor is analyzed, and the stability compensation model of the MEMS is established, and the model coefficient is identified. The error model of MEMS gyroscope and accelerometer is established. The random error model of three axis MEMS gyro and three axis MEMS accelerometer is established by using AR model, and the AR model parameters of the gyroscope and accelerometer are identified. The hardware and software design of the oil well inclinometer system based on MEMS inertial device is completed, and the oil well inclinometer system is developed. The effectiveness of the development system has been proved by the test.
