摘要

针对基于磁通门随钻测量的局限性与惯性技术测量方案优势

结合随钻测量过程中强冲击、震动等环境特点

设计并实现了基于MEMS陀螺仪和加速度计的随钻惯性测量单元。对系统测试发现MEMS陀螺随机漂移误差较大

为此

采用改进时间序列分析法对巴特沃斯低通滤波后信号随机漂移进行建模。与传统时间序列方法建模相比

新方法降低了模型预测误差

滤除MEMS陀螺随机漂移误差更为明显

且在提高精度的同时保证了数据处理实时性。结果表明:系统能够实现近钻头安装

在钻进的同时完成相应参数的测量

达到设计要求。

Abstract

Aiming at limitation of flux gate measurement-while-drilling（ MWD） and make use of advantages of inertial technology

design and realize MWD inertial measurement unit（ IMU） based on micro-electro-mechanical system（ MEMS） gyroscopes and MEMS accelerometers which is suitable for strong impact and vibration environment.MEMS gyroscope random drift error is large when testing system

and therefore improved time series analysis method is used to construct random drift model for MEMS gyro.Comparing with conventional time series method

the new method reduces model prediction error

filter MEMS gyro random drift error is more obvious and ensure real-time of data processing

at the same time improve precision.The test results show that the system can be fixed near-bit and achieve corresponding parameter measurement while drilling

achieve design requirements.
