摘要:针对水平定向钻进具体的测量需求,提出了基于三轴加速度计和三轴磁强计的随钻测量方法,在此基础上利用MEMS微硅加速度计和MEMS磁阻式磁强计进行了系统设计,研制了实际的随钻测量装置,并通过采取特定的措施,如温度补偿和方位校正改善系统性能。结果表明,该装置能够安装在地下钻具的内部,钻进的同时完成倾角、面向角、方位角等参数的检测,倾角精度达±°,面向角精度达±°,方位角精度±°。无论在外观还是在性能上都达到,填补了国内空白。

Abstract:According to actual requirements of horizontal directional drilling, a special measurement-while-drilling method based on 3-axis accelerometer and 3-axis ometer is described in this paper. The entire configuration of the system is designed, and an actual MWD system is established by adopting MEMS micromachined polysilicon accelerometer and MEMS oresistive ometer as the attitude sensors. The system performance is improved by some unique techniques, such as pensation and azimuth correction. Final results show that the MWD system can get the real-time pitch, roll and azimuth while drilling, with the accuracies of ±°, ±° and ±°, respectively. Its appearance and performance reach the advanced international level, and at the same time it fills the domestic
