MODEL CONSTRUCTION AND SOFTWARE DEVELOPMENT OF 3-D HYDROCARBON POOL-FORMING DYNAMICS

According to the theories and methods of system engineering,the constructing train of thought for the system engineering models of hydrocarbon pool-forming dynamics simulation can be summarized as follows. 1)By combining dynamics simulation with non dynamics simulation,the material space for the process of hydrocarbon generation,expulsion,migration,accumulation and dissipation can be reconstructed using non dynamics si mulation. 2)By combining conventional dynamics simulation with system dynamics simulation,the non-linear course of the whole system can be described using system dynamics simulation. 3)By combining numerical simulation with artificial intelligence simulation,the non-linear problems of hydrocarbon migration,accumulation and other local courses can be resolved using artificial intelligence simulation.The key technologies which need to be conquered include the space interpolation and vector cutting technology of 3-D digital geologic bodies,the 3-D back stripping and balancing technology of basin tectonic history and sedimentation history,the dynamic simulation technology of basin tectonic stress field,the simulation technology of mutiple heat source and muti-stage superimposed metamorphism,the trae 3-D conventional dynamics simulation technology of hydrocarbon generation and expulsion,the artificial intelligence simulation technology of hydrocarbon migration and accumulation,the system dynamics simulation technology,of hydrocarbon pool-formation,and the dynamically linking and integrating technology of the whole ststem.The authors discussed these theoretical difficuties and made a series of breakthroughs in the key technologies.On this basis,a 3-D hydrocarbon pool-forming dynamics simulation and evaluation system was established preliminarily and was applied successfully in the practice.
