摘要: 为了科学合理有效地优选油气田开发方案,针对传统的TOPSIS方法(逼近理想解法)在方案综合评选中存在距离理想解近的方案也可能距离负理想解近的问题,对TOPSIS方法进行了改进:引入垂面距离代替欧氏距离来判断方案贴近理想解的程度,并按照各方案与理想解的垂面距离进行排序择优。将改进的TOPSIS方法应用于某油田开发方案优选的实例中,在综合考虑油田开发效果指标、经济效益指标的基础上建立方案优选评价模型,改进的TOPSIS方法优选结果与模糊决策方法优选结果进行对比,对比结论说明了此方法在油气田开发方案优选中的有效性以及使用此方法具有简捷易操作性。

Abstract: In order to scientifically select optimal oil and gas field development plans, this paper presents improved TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) method. The improved method can be used to solve the problem of the conventional TOPSIS that short distance may be coinstantaneous between the schemes to ideal solution and to opposite ideal solution. Vertical distance is proposed to replace Euclid distance by the improved TOPSIS method and the order of priority of all plans is given according to the vertical distance. The effectiveness of the improved TOPSIS is illustrated by applying it to an oil reservoir. The illustration builds TOPSIS evaluation model based on synthetically taking into account of the developmental and economical indexes. Compared with the results of fuzzy comprehensive evaluation method, the calculating results of the improved method is less complex and easily operated.
