摘要
基于有机质成熟作用方面研究的最新成果和系统动力学的方法原理 ,建立了油气系统中有机质成熟中的模拟模型。将该模型应用于南海珠三坳陷的油气系统研究的结果表明 ,温度与压力是控制有机质成熟作用的两个关键因素 ,在温度促使有机质成熟的同时 ,过高的压力对有机质的成熟有抑制作用。压力的抑制作用使有机质达不到应有的成熟度 。
Based on the method of system dynamics and the most recent research on the maturation of organic matter, a simulation model has been established of the maturation history of organic matter in the petroleum system, and the characteristics of the petroleum systems in Zhu\|Ⅲ subbasin are also described in this paper. The result indicates that temperature and pressure are two key factors controlling the maturity of organic matter. Abnormally high pressure has retarding influence on maturation while temperature promotes it. And organic matter under the influence of high pressure is lower in maturity and thus has a low potential of hydrocarbon\|generation as compared with that under normal pressure.
