摘要
提出优选油气田开发方案的新模型，该模型以主成分分析为理论基础，计算开发方案各指标的权系数，根椐各方案指标数值差异所提供的信息来评价方案的优劣；提出原始数据规范化处理、权系数非主观推断、综合评价指数计算的方法与步骤，认为方案综合指数反应了评价方案集中各方案综合性能的相对大小，是进行方案排序的依据；对油（气）田实例进行了评价计算，认为对经济效益影响较大的有年产量递减率和最大采油（气）速度，决定方案排序的最主要因素是投资回收期，据此优选出最佳开发方案。本模型具有简单性和非主观性特点。
lm this psper,a new model for optimum selesting the reservoi developement project is pro-posed out.This nodel is built based on the primary ingredient analytictal theory,by calculating the weightcoefficients of all indexes in development projects to evaluate the project through the differences of index-es.The model provides the way and process for stamdardization of raw data,non-subjective calculation ofweight coefficients and evaluation of comprehensive evalvation index.Application of this model in reservoirevaluation shows the factors that affect the economic benefit are decline rate of annual output and maxi-mun recovery rate.The main factors determine the ordering of project is investmement payback time,and on this basis ,select the best developnent project.
