摘要
摘要:在油田水力压裂微地震事件定位结果的基础上，结合有效微地震事件的时空分布、震级大小、地震矩、震源半径、应力降和b值等地震学参数进行综合研究，并结合研究区域的地质背景和测井资料对水力压裂诱发的裂缝网络进行几何形态分析和应力解释.本文提出的微地震综合分析解释方法可对压裂后储层物性进行综合评价，有利于对储层改造效果进行预测，对油田的水力压裂施工具有指导意义.

Abstract:Based on a micro-seismic hydraulic fracturing monitoring in an oilfield, we systematically analyze the effective micro-seismic events through the spatiotemporal distribution, magnitude, seismic moment, source radius, stress drop and b-value, describe the geometric development of the discrete fracture network and the stress drop in the study area. Then we evaluate the reservoir properties combined with the geological background and logging data. Our micro-seismic analysis technology is helpful to systematically evaluate the fracture network induced by the hydraulic fracturing process, is beneficial to predict the potential fracture zone of the reservoir, and is also a significant guide to a high-efficiency hydraulic fracturing monitoring.
