Formation condition of gas-bearing shale reservoir and its geological research target. Geo- logical Bulletin of China, 2011, 30(2/3):385-392 Abstract: According to sedimentology theory and sequence stratigraphy, favorable environment and time for dark organic shale was analyzed and we consider favorable condition for gas system and take domestic and foreign examples in the progress. It can be con- cluded that dark organic shale, commonly developed in transgressive system tract, especially in condensed section.
