应用理想解排序法优选油田开发方案

针对目前油田开发方案评价方法中主观赋权法和客观赋权法的应用局限,提出用理想解排序法来进行油田开发方案的综合评价,以油田开发理论和实践为依据,将油田开发效果指标、经济效益指标综合考虑,建立了油田开发方案综合优选的数学模型。以某油田设计的8个开发方案为样本,计算得出各开发方案的排序结果,并与模糊决策法和主成分分析法的计算结果进行对比,进而对3种方法得出的结论进行筛选,筛选结果说明该方法用于油田开发方案的有效性和相对于其他方法的优越性。

Application of TOPSIS Method to Optimization of Oil-Gas Field Development Scheme

In light of the applied defects of subjective and objective weight assignment methods of the appraisal approaches for oil-gas field development, the TOPSIS method to comprehensively evaluate the development scheme of oil-gas field is presented. On the basis of the theory and practice of oil-gas field development, a mathematical model by combing with the dynamic indices and the economic indices is developed, by which the comprehensive optimization of oil-gas field development scheme can be made. Taking nine development schemes of a gas field as examples, the ordering results of each development scheme are obtained and compared with those from fuzzy decision and principal element analysis. And then the systematic clustering method is used to verify the conclusions drawn from these three methods. It is indicated that the TOPSIS method has an advantage over the others in optimization of development schemes.
