摘　　要：在油气田开发过程中,针对未开发或者开发初期油藏,常常采用类比法开展开发技术政策研究以及开发指标的预测。类比样本即相似油气田的筛选决定了类比结果的可靠性。综合应用灰关联和地质因素分析法,根据类比参数和类比目标的本质关联,定量确定类比参数和权重,根据被研究对象的油藏类型,引入参数阈值,计算样本油田的相似度,筛选相似度高的油田作为技术政策研究及指标预测的参考样本,使类比分析的客观基础条件更加合理,提高筛选效率及类比结果的可靠性。During the development of oil and gas field,the analogy method is often used to study the development technology policy and predict the development index for the undeveloped or early stage reservoir.The selection of analogy samples,i.e.similar oil and gas fields,determines the reliability of analogy results.Therefore,gray correlation and geological factor analysis are used to determine the analogy parameters and weights quantitatively on the basis of the essential correlation between analogy parameters and analogy objectives.According to the reservoir type of the studied object,the parameter thresholds are introduced to calculate the similarity of the samples,and the oilfields with high similarity are selected as the reference samples for the technical policy research and index prediction,so as to make the basic conditions of the objective basis of analogy analysis are more reasonable,and further improve the efficiency of screening and the reliability of analogy results.
