| 摘 要： | 鄂尔多斯盆地H 地区三叠系延长组主力油层为长6、长4+5、长2 油层组，为典型的低渗透储层。为了掌握该地区各油层地下流体渗流规律及油水两相驱替特征，此次研究运用真实砂岩模型，对H 地区主力油层进行了水驱油实验，并结合薄片鉴定、物性分析、扫描电镜、相渗、压汞等资料，分析出该地区主力油层驱油效率影响因素主要为微观孔隙结构、驱替压力和润湿性，物性对驱油效率的影响不大。

| Abstract: | The main reservoirs of Triassic in H area of Ordos Basin are Chang 6,Chang 4＋5 and Chang 2,which are typical low-permeability reservoirs.In order to obtain the regulations of flowing liquid and the characteristics of two-phase flow,the water/oil displacement experiment in H area is carried out by real sandstone model.Thin section analysis,physical property,scanning electronic microscope,relative permeability and mercury penetration are applied to analyze the influencing factors for the displacement efficiency in this area,which include pore structure,displacement pressure and wettability.Physical property has little effect on the displacement efficiency. |

| Keywords: | displacement efficiency pore structure displacement pressure wettability |
