| 摘 要： | 鄂尔多斯盆地苏里格气田是低渗透砂岩气藏的典型代表,主力含气层盒8段储层物性差、非均质性强、气水关系复杂。根据储层非均质性、孔喉结构配置关系将盒8段储层水分为吸附水、毛细管水、自由水3类,其中吸附水主要吸附于岩石颗粒表面;毛细管水存在于非均质性较强储层的毛细管中;自由水发育在孔隙结构和物性较好的储层。根据区域生烃强度、储层非均质性及微观孔隙结构特征,分析了控制气水分布的主要因素:生烃强度控制气水分布总格局,储层横向非均质性控制储层局部气水分布,微观孔隙结构控制地层水赋存状态。 |

| Abstract: | The gas reservoir in Sulige gasfield,Ordos Basin,is a typical low-permeability tight sandstone gas reservoir.The major gas reservoir He 8 is characterized by bad physical property,strong anisotropy and complicate gas-water distribution.With the tested and explored data,the water is divided into three types as following,adsorbed water and capillary water and free water.The adsorbed water mainly exists in the surface of rock particles;the capillary water exists in the capillary tubes of strong anisotropy rese... |
