Research on optimizing fracturing technology based on microseismic monitoring

针对页岩气开发过程中遇到的压裂施工压力高、改造体积受限等难题,本文通过引入微地震重构算法,建立三维离散压裂裂缝网络地质模型,分析了砂量、液量、排量等压裂工程参数对微地震响应特征的规律,构建了有效液量、砂量、排量等优化压裂设计参数的方法,为后期页岩气压裂提供有效的技术支撑。

In view of the difficulties encountered in shale gas development, such as high fracturing pressure and limited reconstruction volume,a three-dimensional discrete fracturing network geological model is established by introducing microseismic reconstruction algorithm. The law of fracturing engineering parameters, such as sand volume, fluid volume and displacement,on microseismic response characteristics is analyzed, and the effective fluid volume is constructed.The methods of optimizing fracturing design parameters,such as sand volume and displacement, provide effective technical support for later shale gas fracturing.
