摘　　要：储层评价是储层研究中的一项重要内容之一,权系数的确定是储层综合定量评价的关键。采用灰色系统理论法、主成分分析法和层次分析法来确定权系数,并对大庆萨尔图油田北二区东部密井网试验区进行了储层综合定量评价,三种评价方法分类结果具有很好的一致性,解决了储层单因素评价过程中常常出现的评价结果相互交叉、不唯一的问题,有利于对储层进行正确的分类与评价。Reservoir evaluation is very important to reservoir study, and weight coefficient is the key element to determine the comprehensive and quantitative reservoir evaluation. In this paper the methods of gray system theory, main components analysis and analytical hierarchy process are applied to determine the weight coefficient , and evaluation is made for the tense well spacing testing area in east Bei2 region of Saertu reservoir in Daqing oilfield. The results from these 3 methods match with each other well, which can avoid the cross evaluation results and single result due to single element e-valuation process. They are useful for correct classification and e-valuation of reservoirs.
