摘要
In recent years, china shale gas exploration and practice confirmed that shale gas resources distributed in the marine facies, the marine-continental transitional facies and lacustrine facies. Three types of shale gas resources have the same resource potential and different geological conditions （Zhang Dawei, etc., 2012）.
