Abstract

Shale gas mostly develops in shale of high TOC forming reservoir “in place”. These top quality shale mostly grow in shelf facies and marine\|continental transitional facies in passive margin basin, intracratonic basin and foreland basin. The exploration of shale gas is different from the conventional oil and gas. This paper discusses the model for selecting shale gas region mainly by basin types and organic facies. The favorable target is controlled by TOC, organic matter maturity, the thickness and deepness of shale. The brittleness of shale,stratum subsidence history, temperature and pressure of the stratum and gas content in place etc constraint the location of “favorable target”, On the basis of the understanding about lower Cambrian strata in middle and upper Yangtze, it is concluded that western Hunan and Hubei Beidafang tectonic province in north\|west of Guizhou and the area of Weiyuan is the he most favorable exploration area.
