摘要
为了解决老油田长期多油层合采引起的层间干扰和储量动用不均衡等问题,以油藏数值模拟方法为基础,首先运用层次分析法进行单因素影响研究,提出可量化的分层系数概念,然后利用灰色关联方法建立层系划分综合评价标准,形成量化的层系划分标准。该层系划分标准解决了传统的以单因素为基准划分层系过程中出现的划分结果相互交叉、不唯一的问题,有利于对储层进行正确的分类与评价。沙埝油田沙20西断块的油藏数值模拟研究结果表明,应用该方法可提高采收率3.1%,应用效果良好。
To solve the problems of interlayer interference and unbalanced reserves production induced by long period of combined production of multi-layers, on the basis of reservoir numerical simulation, analytical hierarchical process was used to study the influence of single factor, and a concept of quantitative strata division was proposed, and grey correlation method was used to establish a criterion for a comprehensive strata evaluation, by which a standard for quantitative division was established. The problems of cross-over result and none-unique induced in strata classification are solved with the standard, it is beneficial for correct division and evaluation. The result of west Fault Block Sha 20 shows that oil recovery increases3.1% and good effect is obtained,
