介绍了在镇泾油田使用微地震监测方法监测油田压裂、注水获得的可以分辨出初至符号的微地震信号，依据微地震的初至符号做出震源机制解，检测压裂、注水监测的可靠性及压裂、注水效果。结果表明，监测的裂缝方向、注水前缘方向与微地震震源机制节面方向一致，监测结果是可靠的。此项研究提供了一个来自微地震监测本身，可以检测微地震监测结果是否可靠的方法，为那些深度较大、难以取得其他旁证的压裂、注水监测提供了重要检测手段。

This paper describes arrival time of microseismic signals, which were obtained from monitoring fracturing and waterfloodand were used to interpolate mechanisms of micro-earthquake and verify reliability of fracturing and waterflood monitoring. It shows that fracture orientation, waterflood front geometry, and microseismic mechanism nodal plane are consistent, and monitoring results are reliable. This study depicts a selfcheck approach to verify dependability of microseismic mapping itself, and it is an important measurement method for fracturing and waterflood projects of deep formations when no alternative verifications are viable.
