摘要 盆地发育史的数值模拟方法,是在电子计算机上再现盆地的地质、水动力学和热力学的发育过程,比较客观地给出有机质成熟的时间、区域以及油气生成环境的动态变化过程。盆地模拟的数学模型是一组关于地层超压和古温度的非线性偏微分方程初边值问题。文中给出了二维问题的数值解法、模型问题的稳定性理论分析以及计算实例,计算结果表明,计算得到的地层超压和古温度合理,有很强的物理特性。 Numerical simulation of the evolutionary history of an oil-,gas-bearing sedimentary basin may repeat its geological ,hydrodynamic and thermodynamic development history on a computer ,and may more realistically provide basin data about the mature time and region of organic matters and dynamic evironment of petroleum origin and its accumulation, so that it may quatify hydrocarbon generation. In the present paper, mathematical models describing the development of a sedimentary basin are estiblished. The models are characterised by an initial-boundary value problems of a system of nonlinear partial differential equations on the abnormal pressure and the paleo-temperature of the formation. Simulations of a two-dimentional problem is proposed, a theoretical analysis on their stability and a numerical example are given also. The results show that the abnormal pressure and the paleo-temperature computed are reasonable and display their physical characteristics clearly as well.
