高含水油藏长期水驱后，储层孔隙度、渗透率、润湿性都会发生一定程度的改变，岩心的驱油效率会逐渐升高，然而对于驱油效率的影响因素以及变化规律的研究却非常少。针对这一问题，选取高、中、低不同梯度渗透率的四块平行人造岩心开展室内模拟实验，分析比较了驱油效率的变化规律，从而为油田开发决策提供可靠依据。

The porosity, permeability and wettability of high water reservoirs will change after long-term water flooding with the oil displacement efficiency of cores increasing. However, few research on factors that affect the oil displacement efficiency and change rules was implemented. In this paper four pieces of man-made cores with high, medium, low permeability respectively are selected to conduct indoor simulation experiments. Their oil displacement efficiency are analyzed and compared to investigate the change rules that will provide reliable information for future development of the oil-field.
