摘　　要：微地震地面监测主要缺陷在于垂向定位分辨率不足,而井下监测则存在横向定位分辨率较低问题。针对这些问题,通过井中-地面联合监测的方法提高微地震定位可信度,并结合振幅叠加方法对地面噪声进行压制。模拟三维地震数据的反演实验证明该方法的可行性,反演得到的震源位置与模拟震源点位置一致。以山西宁武盆地一次水力压裂监测为例,证明笔者所提出的方法在实际应用中具有可行性。The main drawback of microseismic surface monitoring is the lack of vertical positioning resolution,whereas the borehole monitoring is with the problem of low lateral resolution. In this study,the authors improve the reliability of microseismic positioning by means of joint monitoring of surface and borehole,and the noise is suppressed by amplitude stacking method. The feasibility of the method is demonstrated by the inversion experiments of three-dimensional seismic data. The result of source locations from inversion are consistent with the actual source points. In this study,a hydraulic fracturing monitoring in Ningwu Basin of Shanxi is taken as an example,it is proved that the proposed method is feasible in practical application.
