摘要 微地震监测是目前储层压裂中最精确、最及时、获取信息最丰富的监测手段。微地震监测按照传感器的布置方式可以分为地面监测和井中监测两种。本文以鄂西地区水平井的水力压裂过程中同时布设了微地震的地面监测和井中监测结果为研究对象,针对地面与井中两种微地震监测方式的定位特点、事件数量、监测能量和空间属性等进行了精准定量对比分析;针对二者在对储层压裂的范围、裂缝发育的方向、大小进行追踪和定位等方面的效果等进行了对比分析客观评价了压裂工程的效果。通过对比研究发现井中微地震压裂监测结果中地震波各项属性、裂缝参数信息、解释裂缝破裂过程等成果可以更近距离、更加准确、更加清晰地反映压裂过程中地层裂缝的缝长、缝高、裂缝实时延伸等情况。 Microseismic monitoring is the most accurate and timely method for reservoir fracturing and the most abundant means of monitoring information.Microseismic monitoring can be divided into surface and borehole monitoring according to the sensor layout.In this study,microseismic surface and in-well monitoring results are obtained simultaneously during the hydraulic fracturing of horizontal wells in Western Hubei.The positioning characteristics,the number of events,monitoring energy,and spatial attributes of the two microseismic monitoring methods on the surface and in wells are compared and analyzed accurately and quantitatively;This study compares and analyzes the effects of the two methods in terms of the tracking and positioning of reservoir fracturing and the direction and size of fracture development and objectively evaluates the effects of fracturing engineering.Through comparative research,we found that the seismic wave attributes,fracture parameter information,and the interpretation of the fracturing process in the well microseismic fracturing monitoring results can more closely,accurately,and clearly reflect the fracture length,fracture height,and real-time extension of formation fractures in the fracturing process.
