Focal mechanism of micro-seismic induced by hydrofracture and its signal propagation characteristics

Tang Jie;Fang Bing;Lan Yang;Sun Chengyu;School of Geosciences,China University of Petroleum (East China);  
With the progress of seismic instruments,processing and interpretation techniques, micro seismic plays a more and more important role in describing fracture systems in reservoir management.In this paper we discuss brittle deformation mechanism,micro seismic generation mechanism,fracture dynamic changes,and micro seismic response characteristics,and analyze the possibility to study the fracture time and space distribution rule using micro seismic data.The following observations are obtained:A.Cracks can induce micro seismic,crack tip effects and leakage effects are the main reasons of micro seismic in the process of hydraulic fracturing;B.Micro seismic moment tensor can be decomposed by the eigenvalue decomposition method as DC,CLVD and ISO part;C.Through finite difference forward modeling we can investigate micro seismic signal propagation characteristics.Micro seismic source and velocity model may affect micro seismic waveform characteristics.
