On the reservoir-forming dynamics system

Abstract

In continental basins in eastern China, it is necessary to distinguish dynamic pool-formation systems from petroleum system, according to the dynamic system and process of hydrocarbon migration and accumulation. The paper demonstrates the necessity and possibility of its division, puts forward the concept and dynamic source of dynamic pool-formation system. Three types of the systems, named open-type, closed-type and semiclosed-type are distinguished. The characteristics of oil-gas pool and spatial occurrence in these systems are discussed. In multiple superimposed petroliferous basins, the target and direction for exploration can be determined by dividing different dynamic systems, analyzing the process of hydrocarbon generation, migration and distribution, determining the correlation of oil-source rocks. The methodology for dynamic system analysis is discussed briefly, i. e., comprehensively using the geological, seismic, well-logging and testing data, combined with basin simulation, is the effective way to study dynamic poolformation systems.
