总结我们提出了一个案例研究，详细的源机制反演的微震数据集从水力压裂的页岩气藏。本研究使用地面监测阵列，从75个单独的事件中反演震源机制的剪切和非剪切部分，以表征水力破裂与诱发地震活动之间的关系。我们观察到剪切破坏为主的震源机制与倾滑和走滑运动的意义。我们提出了一个基于层面的解释水力压裂诱发的震源机制的新模型
Summary We present a case study of detailed source mechanism inversion in microseismic dataset from hydraulic fracturing of a shale gas play. This study uses surface monitoring array to invert shear and non-shear parts of the source mechanisms from 75 individual events to characterize relationship between hydraulic fracture and induced seismicity. We observe source mechanisms dominated by shear failure with dip-slip and strike-slip sense of motion. We propose a new model explaining source mechanisms induced by hydraulic fracturing based on bedding plane
