摘　　要：为降低目标钻孔轨迹与实际钻孔轨迹测量结果之间的误差,提出基于粒子群算法的钻孔轨迹测量误差校正方法,建立钻孔轨迹计算模型,确定钻孔倾角、面向角、方位角数值,采集钻孔轨迹数据。分析钻孔轨迹测量的误差来源,构建误差传递状态空间模型,合并历史误差完成钻孔轨迹测量误差的计算。以钻孔轨迹测量误差最小为目标构建误差校正目标函数,对粒子的速度与位置进行更新,并构建适应度函数。通过不断更新计算适应度函数对目标函数进行求解,完成钻孔轨迹测量误差的校正。实验结果表明,所提方法的各个方向的滚转角误差仅在0.3°~1.8°间,且钻孔轨迹与实际值曲线高度拟合,可有效校正轨迹测量误差,并能为地下工程的实际勘探工作提供有价值参考。In order to reduce the error between the target drilling trajectory and the actual drilling trajectory measurement results,a drilling trajectory measurement error correction method based on particle swarm optimization algorithm is proposed.A drilling trajectory calculation model is established,the values of drilling inclination angle,drilling orientation angle,and drilling azimuth angle are determined,and drilling trajectory data is collected.The sources of errors in drilling trajectory measurement is analyzed,an error transfer state space model is constructed,and the historical errors are merged to complete the calculation of drilling trajectory measurement errors.The error correction objective function is constructed with the goal of minimizing the measurement error of the borehole trajectory.The velocity and position of particles are updated,and the fitness function is constructed.The objective function is solved by continuously updating and calculating the fitness function to complete the correction of the measurement error of the borehole trajectory.The experimental results show that the roll angle error in each direction of the proposed method is only between 0.3° and 1.8 °,and the drilling trajectory is highly fitted with the actual value curve,which can effectively correct the trajectory measurement error and provide valuable reference for the actual exploration work of underground engineering.
