摘要: In this paper, an experimental technique has been developed to study the interfacial interactions of reservoir brine−CO2 system at high pressures and elevated temperatures. Using axisymmetric drop shape analysis (ADSA) for pendant case, new makes it possible determine tension (IFT) visualize between brine CO2 under practical conditions. More specifically, dynamic IFT is measured as a function pressure two different It found that gradually reduces constant value, which termed equilibrium IFT. The decreases increases, whereas same parameter increases temperature increases. major observed in include interface disappearance, swelling effect, shrinking wettability alteration. At (T =...
