摘　　要：储量资源是油气公司的重要资产,对油气储量价值进行合理评估,有利于科学开采油气资源以及优化投资组合.科学地评价油气资源价值就是对油气资源进行价值分级.由于储量资源受地质、所处地理位置、交通运输和油藏开发等不同条件的影响,各储量资源会形成不同的级差成本.基于级差成本原理以及油气田勘探开发生产过程的条件,对储量价值评估指标进行选取,构建指标样本集.采用多元回归和德尔菲法对初步选取的21个储量价值评估指标的特征值进行量化表征,应用主成分分析法提取出构成总成本的5类成本级差即外部成本级差、集输成本级差、投资成本级差、开采成本级差和生产成本级差,建立了各成本级差与单因素之间的关系以及储量价值评价指标体系的三级分层结构,进而可以确定不同评价指标的影响权重,最终得到对油气储量的优劣等级进行评价.通过基于成本级差的评价体系建立,可定量表征油气储量的价值等级,为合理评估油田储量价值提供有利的支持.Oil and gas reserves is one of the most important assets of oil and gas companies. Rational assessment of reserves value is both conducive to scientific developing and invest-ment portfolio. Consequently, a comprehensive evaluation system and standards for value classification of oil and gas reserves should be established. Scientifically evaluating the oil and gas reserves value is to classify the oil and gas reserves value. Due to various influences by geology, geographical location,transportation and reservoir development, reserve of resourcesmay gain differential cost. In the light of the theory of cost differential and the characteristic of the exploration and development of the oil and gas resources, reserves value evaluation in-dicators have been selected and the sample set has also been established. The eigenvalue of reserves 21 value indicators has been quantified by applying multiple regression and delphi method and then 5 main types of cost differential which include external cost differential, transportation cost differential, investment cost differential, exploitation cost differential and production cost differential have been determined by applying principal component analy-sis. Consequently, not only the relationship between different kinds of cost differential and value indicators,but also the assessment models of oil and gas reserves value has been estab-lished. On basis of that, influence weight of total 21 indicators and value ranking of reserves can be derived,which will provide favorable support for scientific and reasonable value evalu-ation of oil and gas reserves.
