摘　　要：注气区块的优选是一个多目标规划问题,筛选的结果直接关系现场试验的结果。本文以天然气驱为例,分析了影响天然气驱的主要地质因素,运用对偶比较法确定了各影响因素的权重系数,用多目标规划法对影响天然气驱的客观地质条件进行了定量评价,建立了一套适合于天然气驱的低渗油藏半定量筛选方法,并应用该方法对XX油田的开发单元进行综合评价,为现场试验选区提供依据。Gas injection sub-area＇s optimal is a multi-objective programming question, the screening result directly relation to the field test result. This article take the natural gas drive as an example, has analyzed the main geologic factor that influence natural gas drive, has determined using the antithesis comparison method to test each influencing factor＇s weighting factor, has carried on the quantitative evaluation by using the multi-objective programming method to affected the natural gas drive＇s objective geological conditions, has established a set of method which suit for the natural gas driving infiltrates oil deposit semi-quantitative screening , and has carried on the synthetic quality evaluation by using this method to the south area of Zhong Yuan oil field＇s development unit, has provided the basis for the field test in electoral district.
