摘　　要：储层压裂改造主要针对低渗透性储层,通过压裂来提高储层渗透率,增大孔隙度和泄油半径,最终达到油井上产的目的。近几年开展的同步压裂对微地震监测技术要求越来越高,在实时评估同步压裂效果时,对如何优化压裂参数和改善压裂效果提出了更高的要求。对于断层和天然裂缝带发育的致密砂岩储层,在裂缝检测时存在"多解性",文章主要针对压裂微地震同步监测提出一些认识,通过微地震事件属性特征分析断层和天然裂缝带对储层改造的影响,为油田储层改造过程中压裂方案设计与调整及施工过程质量控制提供依据。Reservoir fracturing is mainly to break or develop fractures in low-permeability formations to improve reservoir permeability,increase porosity and oil drainage radium,to improve well production. The synchronous fracturing developed in recent years poses higher demands on microseismic monitoring,requiring much more on frac parameter optimization and fracturing effects improvement. For tight sands with faults and natural fracture belts developed,the frac detection often has multiple results and ambiguity. In this paper some understanding regards the synchronous microseismic monitoring of frac operations is introduced,the effects of faults and natural fractures on reservoir stimulation are studies according to the properties of microseismic events,which will provide evidence or reference for fracturing program planning or modification as well as quality control during stimulation operation.
