摘要: 在原有状态方程型多组分模型的基础上,作者于1988年与华北油田王瑞河同志研讨提出了一种新的凝析油气藏K值多组分模型模拟方法。文中阐述了问题的提出,物理及数学模式;该模型与状态方程型多组分模型一起,先后对SPE 4271一例及我国某凝析油气藏进行了对比模拟计算,得到十分相近的结果。由于该方法能快速地获取K值,从而大大降低了数模中相平衡的计算量和模拟成本,不失为一种有效的新方法。

Abstract: A new K-value compositional model for a retrograde condensate reservoir ispresented in this paper. The major physical phenomena and mathematical model used in the simulator are described.An application of both this K-value model and the compositional model based on the EOS to the example in SPE 4271 and a comdensate reservoir in our country are shown resulting in very good consistency. The new model which obtains K-values in a more effective way can cut down the time and the cost in the phase equilibrium calculation and simulation.
