油气系统动力学的概念模型与方法原理——盆地模拟和油气成藏动力学模拟的新思路、新方法

THE CONCEPT AND PRINCIPLES OF PETROLEUM SYSTEMS DYNAMICS ——NEW THINKING AND METHOD OF BASIN MODELING AND PETROLEUM POOL FORMING DYNAMICS MODELING

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。

Abstract The authors advise to border the concept of the petroleum system so that it can apply to the whole petroleum geological unit sequence and become a new geological entity.The petroleum geologist can see the geological entity from the angle of the system science.It is a combination of a research objective and an abstract model and has a gradational structure as well.The petroleum system is substantially a petroleum pool forming system.The research methods should be the combination of qualitative and quantitative system method.Considering the non linearity existing in the petroleum pool forming process and the current defect commonly existing in the basin modeling and petroleum pool forming modeling,the authors have tried to recommend the ideas and the methods of system dynamics,introduce the concept of petroleum system dynamics and clarify its basic principles,thus,establish the methods architecture of petroleum system dynamics elementarily.
