在固井中,理想的隔离液能够降低井壁和套管壁上因残余合成基或油基钻井液引起的油湿性,提高第一界面和第二界面的水湿性,使水泥更易粘附在套管壁和井壁上,从而提高密封效果。表观润湿性测定仪依据Winsor微乳液理论及模型研制。微乳液在3种相态时所具有的电导不同。当相态由油外相 In cementing, the ideal barrier fluid reduces the wettability of the wall and casing wall due to residual synthetic base or oil-based drilling fluids and improves the wettability of the first and second interfaces, making the cement easier to adhere to the sleeve Tube wall and shaft wall, thereby enhancing the sealing effect. Apparent wettability tester based on Winsor microemulsion theory and model development. Microemulsions have different conductivities in the three phase states. When the phase state from the oil phase
