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.
