| 摘 要： | 为了提高低渗透油藏采收率,分析了影响采收率的因素,低渗透油藏的主要特点是是储层物性差(孔隙度低,渗透率低)、地层流体自然渗流能力差、产能低、产能递减快。水的自发渗吸对提高低渗透油藏采收率十分有利,通过渗吸实验研究了低渗透砂岩油藏渗吸规律,结果表明亲水岩心渗吸量与时间呈指数增加关系,渗吸采收率受岩样接触面积、孔隙度、渗透率等因素影响,渗吸采油将为低渗透砂岩油藏的开发提供新的思路,该成果对提高低渗透油藏采收率具有重要意义。

| Abstract: | In order to enhance low permeability reservoir recovery,factors of effect recovery were analyzed,low porosity and permeability is the main character of low permeability,fluid flowing through porous medium is poor,this lead to low production and rapid deliverability decrease.However imbibition is favorable to low permeability reservoir,low-permeability sandstone reservoirs imbibition laws were studied through experiment,results showed that the amount of core Imbibition and time appear exponential increase re... |
