Received Date: 23 May 2012

摘要: 以渤海海域A油田为例,探讨了海上油田中高含水期河流相油田储层表征的内容及特点。以精细地层格架为基础,在平均井网密度350 m的情况下,形成了河流相储层沉积相研究的方法与流程,确定了三维定量表征储层物性的原则,建立了主力油组地质模型。在此基础上提出了4种剩余油分布模式,为A油田中高含水期的综合调整提供了地质依据。

Abstract: Taking the north block of the oilfield A as an example, this paper discusses the contents and features of fluvial facies reservoir characterization in high water cut stage. Upon the basis of a high resolution stratigraphic framework, the method and working procedure of facies analysis for a fluvial reservoir is constructed at a well space of 350m. The principles of 3D quantitative reservoir characterization as well as the 3D reservoir model are established. Four types of the distribution pattern of remaining oil are recognized. The results may provide support to the comprehensive adjustment of oil production at a high water cut stage in the oilfield.
