摘要
油田开发方案的优劣受众多指标的影响.在进行多方案优选时,一般做法是采用单一指标,有时即使综合权衡其它因素,也往往是凭经验定性判断,缺乏科学的运作方法和程序.本文提出用层次分析法确定各指标的权重,将各方案相应于各指标的优劣度定量化,并在此基础上用加权平均法最终确定多指标下方案优劣度的大小.在区块方案多指标综合评价中,首次引入经济风险指标和技术风险指标.应用层次分析法和模糊数学理论可以使油田开发方案的综合优选决策建立在科学和定量的基础之上.
The applicability of oilfield development plans is affected by many indices. When selecting the best one among multiple development plans, a single index is commonly adopted. Even sometimes other factors are comprehensively considered, the optimization is determined by experiential judgments and lacks scientific operation method and program. In this paper, the weight of each index is estimated by using the hierarchic analysis process, and the applicability of each plan corresponding to each index can be quantified. On this basis, the applicability magnitude of each plan can be established and multiple indices by a method of weighted mean. In addition, economic and technical risk indices are introduced for the first time into multi_index evaluations of block development plan. The application of the hierarchic analysis process and the fuzzy mathematics has provided a scientific and quantitative foundation for comprehensive optimization of oilfield development plans.
