| 摘 要： | 本文提出了一个适合我国凝析油气藏模拟计算的拟三维模型,即多层二维三相全组分模拟器。采用有限差分方法和隐式压力、显式饱和度和显式组成的方法求解该模型。模型中还引进了包括六个油气状态方程(即PR、SRK、PT、SW、LLS及SHBWR)的相平衡闪蒸分析方法和物性参数计算方法。它可用于凝析油气藏一类油气田的开发设计和动态预测。文章还对凝析气藏的衰竭及循环注气开采过程进行了实例模拟计算,并获得了满意的结果。

| Abstract: | In this paper, a pseudo-three dimensional model has been developed for the design and the performance predicton of gas condensate reservoir development. It is so called a multi-layer two-dimensional, three-phase, compositional simulator. The model is solved by finite difference scheme and IMPE3EC m:-thod(implicit pressure, explicit saturation and explicit composition). On the other hand, an efficient and accurate flash analysis is used in this model. Included in the calculation of phase equilibrium are six equations of state, namely, the PR, the SRK, the PT, the SW, the LLS and SHBWR equations of state. As an example, this compositional model was used to simulate the production process of condensate gas reservoirs during their depletion and cyclic gas injection, and satisfactory results were obtained. |
