摘要
低渗透油藏的储层由于沉积等原因导致了储层的非均质性较大,并且因为构造等原因造成的油水分布无规律性,导致在开发中存在大量剩余油。本文以马岭油田某区长10储层为例,对其在油田开发中后期存在的采收率低、产量低等问题进行剩余油分布研究,通过更好的了解分布规律来进行开发区块和技术的调整,提高采收率。
In low permeability reservoir,the plane sedimentary type and geometry of change are different because of differencesof permeability and its combination type of longitudinal each layer At the same time,due to complex water-oil relations of block,thedistribution of remaining oil geological reserves is barge and complicated. In this paper,a series of approaches are discussed to study theremaining oil distribution in block of Maling oilfield. Various methods are carried out to study the regular pattern of the remaining oil andforecast the remaining oil in-place.
