液固表面的润湿热和吸附热

RESEARCH ON WETTING HEAT AND ADSORPTION HEAT BETWEEN THE SURFACE OF SOLID AND LIQUID

    摘要
  • 摘要: 为了深入了解润湿热和吸附热的意义,从概念和相互关系方面进行了探讨,分析了它们在采油中的作用和应用,并进行了渗吸驱油试验。理论分析和试验结果表明:润湿与吸附关系密切,在采油中起着举足轻重的作用;油在岩石表面的润湿热越大,越不容易被驱走;驱油剂溶液在岩石表面的润湿热越大,越有利于自发渗吸,有利于提高洗油效率;驱油剂在岩石表面的吸附热越大,吸附能力越强,越有利于改变岩石表面的性质。

     

    Abstract: In order to understand the meaning of wetting heat and adsorption heat,concepts and relationships were discussed.The function and application of which during oil recovery were analyzed and some imbibition experiments were made.The theoretical analysis and the experimental results show that the relationship between wetting and adsorption are close and they play important roles in oil recovery.The greater the wetting heat of oil on rock surface is,the more difficult displacing the oil is.The more greater the wetting heat of oil displacement agent solution on rock,the more easy to imbibition,and more favor for enhancing oil recovery.If the adsorption heat of oil displacement agent on rock is greater,the adsorption capacity is higher,more favor for changing the surface property of rock.
