在我国东部陆相盆地找油过程中,需要在含油气系统中以油气的运移和聚集的动力学系统和过程为核心,进一步划分出成藏动力学系统。文中作者论证了划分的必要性和可能性,划分原则及其动力学源泉;介绍了开放型、封闭型和半封闭型三种类型的成藏动力学系统.论述了成藏动力学系统中油气藏形成特征和分布规律。文章以渤海湾复式油气区多成藏动力学系统叠置的盆地为例,通过划分其不同的成藏动力学系统,具体分析各个系统油气形成、运移、分布的动力学过程,明确其油源对比特征,从而可以明确寻找不同动力学系统油气藏的目标和方向。该文还概略地提出了成藏动力学系统的研究方法,即综合运用地质、地震、测井资料以及各种测试方法获得的油源对比资料与盆地动态模拟相结合的方法,是研究复式油气区多成藏动力学系统的有效方法。
During the process of oil discovery in the continental basins in the east of China, it is necessary to further divide the reservoir-forming dynamic system in the hydrocarbon-bearing system with the dynamic system and process of hydrocarbon migration and accumulation as the core. In this paper, the authors demonstrate the necessity and possibility of division, the principle of division and the source of their dynamics, and introduce three types of open-type, closed-type and semi-closed-type kinetic systems of accumulation, Tibetan formation and distribution of the law. Taking the basin with multi-reservoir dynamics system overlaid in the Bohai Bay compound oil and gas region as an example, the dynamics of formation, migration and distribution of oil and gas in each system are analyzed in detail by dividing different reservoir dynamics systems, Source contrast features, which can clearly find different kinematic systems of reservoir targets and directions. The article also briefly proposed the research methods of reservoir dynamics system, that is, the method of integrating the oil source contrast data and basin dynamic simulation, which is obtained by comprehensively using geological, seismic, well logging data and various test methods, An effective method for regional multi-accumulation dynamics system.
