建立了LPS交联聚合物溶液体系深部调剖封堵模拟模型 ,用数值模拟方法研究了LPS体系对油藏渗透率和储层非均质性的适应性 .结果表明 ,随着油层平均渗透率的增大 ,采用LPS体系调剂时 ,油层的采出程度逐渐降低 ,在同一平均渗透率下 ,不同渗透率变异因数油藏的LPS体系驱替的采收率差别很小 ;对于平面非均质层 ,LPS体系驱替的采出程度随着渗透率变异因数的变化是非单调的 ,中间出现一个峰值 ,该数值在渗透率变异因数为 0 .6 0到 0 .80之间 ,为采用LPS体系提高采收率的最佳点 .
The simulation model of deep profile control and plugging of LPS crosslinked polymer solution system was established and the adaptability of LPS system to reservoir permeability and reservoir heterogeneity was studied by numerical simulation.The results show that with the average permeability of reservoir The recovery of LPS reservoir with different permeability variation factors is very small under the same average permeability; for the case of planar heterogeneity LPS system, the variation of permeability variation factor is non-monotonous with a peak in the middle. The value of permeability variation coefficient is between 0.060 and 0.80, The best point to improve oil recovery.
