摘要
本文介绍一种网格迭加(Superpose Grid)双孔双渗拟组分模型。它与双孔单渗模型相比、适用范围更广、更具一般性,同时,还兼有黑油模型和多组分模型的某些优点,如:相平衡计算简洁、可模拟凝折油气藏等。文中给出了数学模型、离散过程及求解方法等,本模型巳在华北苏桥凝析气藏的开发设计中得到实际应用。
The model described here is a dual porosity/dual permeabilty core with the superpose grid structure. It can be applied in a rather wide range as compared with the conventional dual porosity/single permeability model. In addition, it has several good feature as compared to both black oil model and multi-compositional model, for example, a more simplifled method to cal- culate phase equilibrium and the ability to simulate condensate reservoir etc. This paper give maths model, procedure of discretization and the approach to get the solution of the maths model. The application of this model in the study of Su 1. condensate reservoir is presented at the end of the paper.
