Abstract: To adapt to the development of oilfield development engineering and change the situation of single evaluation of oilfield development effect and that to determine evaluation targets was only based on experience in the past, comprehensive evaluation on development effect form an overall view need to be conducted. Selecting evaluation targets presupposes comprehensive evaluation. Right or wrong selection is correlated with the reliability and credibility of evaluating results. After brief analysis about the advantages and disadvantages of the selecting method, this paper simplified method of primary scoring by the experts, combined the proportion method, and the analytic method by gathering categories. Combining the methods is to combine qualitative targets with quantitative ones, integrate technical, economic and management targets, and select out representative and independent factors that influence oilfield development effect. It could reflect the targets that influence oilfield development effect and avoid integration nondimensional processing of evaluating targets caused by different dimension, units and numerical magnitude. Calculating load was reduced, and working efficiency was thereby increased. From the results obtained from the two calculating methods, the new method is feasible.

摘要： 为了适应油田开发工程的发展,改变过去对油田开发效果单一评价及确定评价指标凭经验的状况,需要对油田开发效果进行整体意义上的综合评价。筛选评价指标是进行综合评价的前提。筛选的正确与否,关系到评价结果的可靠性与可信度。在简单分析了筛选方法的利弊后,采用了简化的专家一次打分法、比重法和聚类分析法的组合方法。组合筛选方法将定性与定量指标相结合,结合技术、经济、管理等方面指标,从系统论的整体性出发,在影响油田开发效果的因素中优化筛选出具有代表性、独立性,并能反映评价油田开发效果的指标,避免了因量纲、单位、数值量级的不同,而造成的筛选前需进行评价指标一致化与无因次化处理,降低了计算量,提高了工作效率,简单便捷。从筛选评价指标组合法的两种计算方式的结果看是可行的。
