摘　　要：水平井水力压裂储层改造能够有效提高油气产量,应用井中微地震监测即时评价压裂效果的技术完善而成熟。将微地震数据与三维地震数据结合进行综合分析,能够有效提高压裂监测解释精度。辽河探区在微地震数据结合地震数据综合解释应用成功地指导了油气田开发井位部署、井网优化。以辽河探区L区块的水力压裂监测为例,将压裂区域地震数据提取的相干体属性与微地震叠合显示,研究其相关性,分析微地震事件的空间分布特征,揭示天然裂缝及微断层对压裂缝网形成的作用机理,对比微地震事件点位与地震属性的关系,为后期压裂施工和井位部署提供了可靠的理论基础。The hydraulic fracturing reservoir renovation of horizontal wells can effectively improve oil and gas production,and the technology of using micro seismic monitoring in wells to evaluate the fracturing effect in real-time is mature and complete.Combining micro seismic data with three-dimensional seismic data for comprehensive analysis can effectively improve the accuracy of fracturing monitoring interpretation.The Liaohe exploration area has successfully guided the deployment of oil and gas field development wells and optimization of well networks through the comprehensive interpretation and application of micro seismic data combined with seismic data.Taking the hydraulic fracturing monitoring of Block L in the Liaohe exploration area as an example,the correlation between coherent body attributes extracted from seismic data in the fracturing area and micro seismic superimposed display is studied.The spatial distribution characteristics of micro seismic events are analyzed,and the mechanism of natural fractures and micro seismic faults on the formation of fracture networks is revealed.The relationship between micro seismic event locations and seismic attributes is compared,providing a reliable theoretical basis for later fracturing construction and well deployment.
