中文摘要：

随着中国各大油田开采力度的加大，开采阶段基本都进入了含水率较高的后期阶段，为了进一步满足日益增长的能源消费需求、提高采收率，CO2驱油技术逐渐走人人们的视野，备受各大油田的青睐，成为目前油田上提高采收率的重要技术之一。CO2驱油效果受众多因素影响，油藏非均质性是其中一个非常重要的因素。本文基于油藏非均质性对CO2驱油效果的影响程度做出评价，并在评价结果的基础上进一步完善非均质油藏CO2驱油方法。重点分析了两种非均质性对CO2驱油效果的影响，评价了两种非均质性对CO2驱油效果的影响程度。

英文摘要：

With the increase of exploitation of major oil fields in China, the mining stage basically entered the later stage of high water content. In order to further meet the increasing energy consumption demand and improve the recovery rate,CO/flooding technology gradually People＇s vision, much of the major oil fields of favor, has become the current oil field to improve oil recovery, one of the important technologies. CO2 flooding is affected by many factors, and reservoir heterogeneity is one of the most important factors. In this paper, the influence of reservoir heterogeneity on CO2 flooding effect is evaluated, and the method of CO2 flooding in heterogeneous reservoir is further improved on the basis of evaluation results. The effect of two heterogeneity on CO2 flooding was analyzed, and the influence of two heterogeneity on CO2 flooding was evaluated.
