摘　　要：针对某些注气油藏,在降压过程中形成"非天生"的泡沫油,利用数值模拟研究泡沫油机理及后期参数优化及开发效果预测方面与其他泡沫油的数值模拟有很大区别。本文应用CMG中WINPROP相态模拟软件包,结合室内实验结果,对鲁克沁深层稠油油藏地层原油PVT实验数据进行拟合计算,主要包括地层流体和天然气组分合并、脱气油和含气油相态拟合、饱和压力、气-液相平衡计算等,最终得到能反应实际地层流体的性质变化的流体参数场,为下一步泡沫油数值模拟研究提供理论基础。Different from the normal that existed such foamy oil called non-natural is produced in the decompression process of some gas injection reservoir. The foamy oil is generated by the formation pressure though gas injected into increase the gas oil ratio. This is very different in the numerical simulation using the results of numerical simulation of parameter optimization and foamy oil mechanism to forecast the development effect from other foam oil.In this paper, combined with laboratory experiments of Lukeqin, the WINPROP phase simulation software of CMG is used to calculate fitting the PVT including the combination of formation fluid and gas components, phase matching, the saturation pressure, gas-liquid degassing oil and gas oil phase equilibrium calculation and so on. And finally obtain the parameter field which can be on behalf of changes in fluid properties of actual formation fluid to provide the theoretical basis for the further study on the numerical simulation of foamy oil.
