高河矿地面水力压裂裂缝监测及其识别方法

Ground Hydraulic Fracture Crack′s Monitoring and Identification Methods in Gaohe Mine

针对高河矿现采用的地面水力压裂工艺,结合煤诸层自身特点,根据微震监测系统监测到的微破裂时空分布规律,对压裂施工过程中采集的数据进行处理,识别压裂作业过程中产生的微震事件。对裂缝井周围产生的压裂裂缝的空间展布和裂缝的延伸进行分析,测量出压裂过程中微震事件产生的长度、高度、裂缝位置等信息。

In connection with the Gaohe mine's now used technology ground hydraulic fracturing,combined with the characteristics of each seams, According to temporal and spatial distribution of micro-fractures, which is measured by micro-seismic monitoring system. Process the data collected from fracturing procedure and identifies those micro-seismic events during fracturing operations.Analyze the spatial distribution and extension of crack, which appeared around the fractured well,measure the length, height, location and other information of micro-seismic events during experiment.
