| 摘 要： | 针对自动垂直钻井系统中采用的单轴稳定平台,在满足小井斜动态旋转条件下,提出一种新的以三轴加速度计和三轴磁通门测量信号为数据源的井斜方位动态测量算法,并考虑不同倾斜角和钻铤转速等因素的影响,对算法进行仿真研究.结果表明:小角度倾斜的方位角动态测量精度受倾斜角和真实方位角影响,在方位角相同的情况下,倾斜角越大,测量结果的误...

| Abstract: | For the single-axis stabilized platform in automatic vertical drilling system,under small inclination angle and dynamical rotation conditions,a new inclination and azimuth dynamical measurement algorithm was proposed based on triple axis accelerator and magnetic fluxgate sensors.Considering the effect of different rotation speeds,inclination angles and other factors,the algorithm was studied by numerical simulation.The results indicate that the dynamical measurement accuracy of small inclination angle is re... |
