摘　　要：为更好地了解微震监测技术在实际应用中的定位误差,以IMS微震监测技术为例,在查阅大量相关文献和结合现场应用的基础上,重点分析了其在实际运用中的定位误差影响因素,并给出减少定位误差的相关原则和建议,指出传感器空间布置方式是影响定位精度最重要的因素,合理的空间布置方式能减小初始误差对定位结果的影响,合理选择传感器类型、P波S波的正确拾取及速度优化能在一定程度上提高定位精度。To better understand the location error of microseismic monitoring technology in practical application,IMS microseismic monitoring technology was taken as an example.Based on a large number of relevant literature and field application,the influence factors of location error were emphatically analyzed in practical application,and relevant principle and suggestions for reducing location error were proposed.The space arrangement of sensor was considered as the most important factor of affecting positioning accuracy.Reasonable space arrangement could reduce the influence of initial error on positioning results.The reasonable selection of sensor,as well as the correct picking and speed optimization of P wave and S wave could improve the positioning accuracy to a certain extent.
