本文推荐了一种用PR状态方程计算等体积消耗数据的方法。计算结果与实验值以及与国外文献计算位的对比,符合程度较好。 笔者还计算了中原油田文72井凝析气的等体积消耗数据,并根据此数据用相平衡计算方法预测了定容凝析气藏以消耗方式开采时的生产动态。本文的贡献是解决了计算方法,待国内有相应实验数据时即可投入实际应用。 文中1—4节概述了以状态方程为基础的相平衡计算方法,包括加速逐步迭代法及带回程序的推荐应用。
In this paper, we propose a method to calculate equal volumetric consumption data using the PR state equation. Calculation results and experimental values as well as comparison with the foreign literature to calculate the bit, the degree of conformity is better. The author also calculated the equal volumetric consumption data of condensate gas in Wen-72 well of Zhongyuan Oilfield and predicted the production dynamic of condensate gas reservoir of Ding-Rong condensate gas production by consumption mode based on this data. The contribution of this paper is to solve the calculation method, until the domestic experimental data can be put into practical application. Section 1-4 summarizes the phase equilibrium calculation based on the state equation, including the accelerated iterative method and the recommended application of the program.
