| 摘 要： | 为了提高水平定向钻进的轨迹精度,对轨迹误差的影响因子进行了细致的推导,并结合工程实际对公式进行了一系列合理的简化。在公式的推导和简化过程中,针对施工中的不同条件对公式进行了选择性优化,使钻进轨迹误差受测量误差的影响尽量减小。利用实际施工中的具体环境参数,仿真了在相同测量误差下的轨迹误差在优化前后的差异,从而证明了该优化...

| Abstract: | The factors affecting the drill trajectory were analyzed to improve the trajectory accuracy in horizontal directional drilling.The engineering equations were simplified and optimized to show how to reduce the trajectory error caused by measurement errors.Simulations with real environmental parameters showed that the errors were reduced by the optimization.Thus,the results give guidance on how to improve the trajectory accuracy. |
