英文摘要： The project takes shale gas that the forecast and monitoring of organic matter content, reservoir rock brittleness and fracture development as the main scientific problems. According to the petrophysical properties testing of Shale gas as research foundation and basis, we analyze that the characteristics of shale reservoir rock mechanics and microstructure change have the influence of seismic elastic properties and their response mechanism, and establish the connection with reservoir rock seismic features and shale reservoir characteristics parameters. We predict the distribution of shale gas reservoir viscoelasticity using the methods of oil seismology and microseism. Through the test with time response and frequency characteristics of rock sample electrical parameters, the relations between shale gas and total organic carbon content, we set up the geological and geophysical model with electromagnetic detection, the analysis on the electromagnetic response characteristics, and then the organic carbon content is calculated by means of the electromagnetic and induced polarization effect. Based on the technology of microseismic surface wave extraction, surface wave inversion, microseismic source location and well seismic monitoring on the ground, we do the research of shale gas well fracturing process and developm
