作者建议拓广“油气系统（ｐｅｔｒｏｌｅｕｍｓｙｓｔｅｍ）”概念，使之适合于整个含油气地质单元序列，成为石油地质学家从系统科学角度所看到的、研究对象与抽象模型相复合的、具有层次结构的新型地质实体。“油气系统”实质上就是油气成藏系统，其研究方法，应当是定性与定量相结合的系统方法，考虑到油气成藏过程存在非线性特点，以及当前盆地模拟和油气成藏模拟普遍存在的缺陷，作者尝试引进系统动力学的思路与方法，提出油气系统动力学的概念，并阐述了它的基本原理，初步建立了油气系统动力学的方法体系。
The authors propose to broaden the concept of “petroleum system” to fit the entire sequence of petroleum-bearing geologic units, to be recognized by the petroleum geologists from the perspective of systems science, to be integrated with abstract models and with hierarchical structures New geological entity. “Oil and gas system” is essentially an oil and gas accumulation system. Its research method should be a systematic method of combining qualitative and quantitative analysis. Considering the nonlinear characteristics of hydrocarbon accumulation process and the current basin modeling and hydrocarbon accumulation modeling are ubiquitous Defects, the author attempts to introduce the ideas and methods of system dynamics, put forward the concept of hydrocarbon system dynamics, described its basic principles, and initially established a method system of hydrocarbon system dynamics.
