| 摘 要： | 基于泡沫组分物质守恒原理,考虑泡沫生成、破灭、运移现象,建立聚合物强化泡沫驱渗流的多组分数学模型,有效反映油相消泡和聚合物稳泡作用机理,采用自适应隐式方法进行求解.通过拟合泡沫驱替实验结果,验证数学模型的有效性.对某油区泡沫先导试验区进行跟踪数值模拟,分析泡沫驱渗流特征,结果表明,强化泡沫体系能够在地层稳定存在,并不断向生产井推进,从而大幅度提高原油采收率.

| Abstract: | A muhi-component mathematical model characterizing polymer enhanced foam flooding filtration is established with mass conservation principle of foam components. Considering combination of foam generation, coalescence and migration phenomena, the model effectively reflects mechanism of oil phase foam coalescence and polymer foam stabilizing. Differential numerical solution is conducted with adaptive implicit method. Validity of the mathematical model is verified with experiment. Meanwhile, taken foam flooding pilot region of a oilfield, a numerical simulator is employed to study filtration characteristics of enhanced foam flooding. It is indicated that the foam system could exist stably in the formation and gradually advance to production wells to improve oil recovery. |
