| Abstract: | In order to improve the application effect of integrated geophysical methods in shale gas exploration, this paper conducted a research of integrated geophysical methods in the early investigation and evaluation stage of shale gas resources based on the shale gas resource survey and evaluation project in Jiangsu Province. The objective is to establish a set of exploration technology which can adapt to the previous available data and complex tectonics in Jiangsu Province, in order to identify the shale horizons of marine, land-sea transitional and continental facies in different periods. The result shows that four sets of shale strata in Jiangsu section of the Lower Yangtze region are identified by an effective technical combination through the optimization of exploration network and exploration methods, the analysis of physical parameters, and the introduction of advanced exploration methods and process methods, which has greatly reduced the investigation cost and further improved the interpretation accuracy and recognition capability |
