Control Action of Contemporaneous Structure on Reservoir-forming in Jiyang Depression

Investigated from the aspect of relationship among tectonic movement, sedimentation and reservoir-forming, the paper demonstrated systematically the action of contemporaneous structure controlling the sedimentation and reservoir-forming. Results show ed that the movement of contemporaneous structure is good to reservoir-forming in several ways, such as hydrocarbon generation, migration, accumulation and preservation. Analysis showed that after the discovery of big-middle scaled oil-gas reservoir in Jiyang depression, the theories of sequence stratigraphy, petroleum system and kinetics of reservoir-forming should be utilized at their most to enhance exploration effect.The theories mentioned above can be used to study the control action of contemporaneous structure to the process of sedimentation, entrapment-forming, reservoir-forming and spatio-temporal matching feature of source-reservoir-caprock. Study on contemporaneous structure is converting from qualitative method to quantitative method and temporal method. Dynamical mechanism is emphasized in the study, and simulation of quantitative process is perfecting as well.
