摘要
建立了一个油、气、水三相多组分三维油藏数值模拟模型。用油气状态方程进行流体相平衡和物性参数计算，该模型采用全隐式方法进行求解。与以往不同的是，模型中考虑了ＣＯ２在水中的溶解，并提出了ＣＯ２在水中溶解度的计算方法，同时给出了考虑ＣＯ２在水中溶解后多组分模型求解的离散化方法以及水相物性参数的计算方法。开发和研制了三维三相全组分数值模拟软件，利用该模型对长庆靖安低渗透性油田注气开发过程进行了模拟计算，获得了满意的结果。该模型还可用于挥发性油藏、凝析气藏、注气等开发过程的模拟计算。
A three dimensional multi component numerical model for oil, gas and water phases was established. The phase equilibrium and property parameters were calculated by using the equation of state. The simulator can be used to calculate CO 2 solubility in water phase. At the same time, the method for calculating water phase property with CO 2 solubilization is described. According to the method reported in this paper, a three dimensional multi component numerical simulator for oil, gas and water phases was developed. An application example in Changqing oilfield is given, and the satisfactory results have been obtained. The new simulator can be used to simulate the developing progress of a volatile oil reservoir, gas condensate or gas injection reservoirs.
