摘要:

针对每个注气候选油藏都包含有各类影响因素,很多影响因素既相互依赖,又相互矛盾,给决策、评价带来很大困难等特点,介绍了筛选注气候选油藏的指标评价体系及指标评价范围,并建立了筛选注气候选油藏的模糊优选模型与计算步骤。该方法在采用模糊层次分析法求得了同一油藏各评价参数权重的基础上,建立了用于筛选成组候选油藏的模糊优选模型,实例表明该方法可正确评价和比较各候选油藏注气潜力的大小。

Abstract:

Due to every gas injection candidate reservoirs having different kinds of affective factors, the factors depend on eachr soad ech other, which bring some difficulties in deciding and evaluating to manager, the evaluation index system and the evaluated range of the index was introduced in the paper, the fuzzy optimum screening model of the candidate reservoir for gas injection and its calculate step was established, On the foundation of obtaining the same reservoir parameter weight which was calculated by fuzzy gradation analysis, the fuzzy optimum screening model which applied to screening the unitian rirga injection was successfully established. The example has proved that this method would rightly evaluate and compare the potential of the candidate reservoir to gas injection.

Key words: fuzzy mathematics, optimum screening theory, reservoir engineering, gas injection, reservoir screening
