由于研究区为低孔-低渗及特低孔-特低渗储层，孔隙结构以小孔微细-微喉道为主，渗流阻力较大，对其储层流体的微观渗流特征进行研究可以为油田开发提供必要的指导。本文主要从油驱水、水驱油微观渗流特征、剩余油的类型及成因、驱油效率的影响因素等方面进行分析，摸清储层微观渗流特征。

Ordos basin, northwest of the low porosity and low- low permeability and ultra-low hole - low permeability reservoir, the pore structure of tiny holes - Micro throat, seepage re- sistance,its micro-reservoir fluid flow charaeteristicsresearch can provide the necessary guid- ance for the oilfield development. In this paper, driving water from the oil, water flooding mi- croscopic seepage characteristics,Types and Causes of the remaining oil, the oil displacement efficiency influencing factors were analyzed to find out the reservoir microscopic flow charac- teristics.
