Organic-rich shale is widely developed in China geological history, so shale gas exploration and development have promising prospect. The effective combination of rock physics and seismic technology can realize effective prediction of shale reservoir distribution, thickness and the physical properties. And it also can characterize reservoir fracture development, stress distribution, and design horizontal well trajectory using reservoir anisotropy, wave field data and other information. In the project, we will conduct systemic and scientific researches on shale gas reservoir rock physics and seismic response mechanism. Using electron microscopy and 3D imaging technology, the gas shale reservoir rock microstructure and pore feature is quantitatively characterized. Through rock physical elastic parameters measurement, CT imaging of fracture characteristics, as well as micro-seismic monitoring in the fracturing process of shale gas reservoir, we quantitatively analyze of rock structure and rock physical parameter variations in fracturing process of shale gas reservoir. By combinations of seismic physical model, seismic numerical simulation, and data analysis of S wave split and seismic data application, we can ensure seismic wave propagation characteristics and reservoir characterization mechanism of shale gas reservoir. This study will provide us with the direct basis for ensuring shale gas resource evaluation method and standards suitable for China geological conditions. This study is valuable for shale gas exploration and development in China since it is the theoretical experimental base for shale gas reservoir seismic identification, comprehensive evaluation and related novel technologies development.
