Hydrocarbon sources controlled by basin prototype and petroleum accumulation controlled by basin superposition: thoughts and technology of resource grading evaluation and exploration optimization in petroliferous basins

The formation and evolution of petroliferous basins in China are characterized by multi-cycles, multi-genesis, multi-stages and superposition. In these basins with their own style and characteristics, based on the analysis of 3T (time, tectonic setting, thermal regime)-4S (subsidence, sedimentation, stress, style)-4M (material, maturation, migration, maintenance) proposed by Mr. ZHU Xia, and the research and practice of a large number of basins in eastern and western China, a basin analysis and evaluation of "prototype controlled sources and superposition controlled accumulation" is summarized, a "3342" (3 controls, 3 evolutions, 4 effects and 2 centers) analysis method is proposed, and a TSM basin simulation and resource evaluation system is developed. These methods and systems play an important guiding role in the analysis, research and exploration evaluation deployment of different exploration stages and types of basins in China.
