摘要: 注天然气混相骤悬提高原油采收率的重要手段之一。在注富气和黄气天然气混相题替机理分析和注气工程势态分析的基鹅上,找出各种影响注气效果的因素,并道取其主要的参数,建立共相应的评价指标体系;结合油层物理和油藏工程评平价方法,在对相应评价指标进行量化的基础上,引入现代决策分析方法,利用基于理想最优方案的指标赋权法,对候造油费进行维违排序和综合评价,体现各种影响因素对注气的整体影响,最后用于矿场试验。

Abstract: Natural gas injection miscible flooding is one of means for EOR. This paper presents the factors thal affect gas injection results based on the analysis of lean-gas and rich-gas injection miscible flooding mechanisms and gas injection performance analysis. by which the related assessment index systems are establisbed. Combining with reservoir physics and reservoir engineering evaluation methods, the rclated indices are quantified. The modern decision analysis method and optimal scheme index assignment inethod are used to syntbheti-cally screen and assess the candidate reservoir. The result shows that this method could reflect the influences of various factors on gas in-jection, and will be applied on pilot test.

Key words: gas injection, miscible flooding, screeningg index, assessment
