Abstract


Based on a large number of physics simulation experiment data, mathematics relationship problems of the correlation of imbibition efficiency influence factors have been solved, and the correlation equation have been established. Field ML and field YT was chosen to represent the extra-low permeability field, Field JY and field QX was chosen to represent the ultra-low permeability field. The impact trend of imbibition efficiency with interfacial tension, emulsion stability, penetration force and viscosity has been found. A result has been found through the R factor analysis by common factor variance and coefficient of variation method, the impact order on imbibition efficiency of oil-wet core or oil sand is interfacial tension, emulsion stability, viscosity ratio and penetration force ratio. The four factors and three factors structural equation models have been established, and passed the model test. The impact of cross term is considered. This study has great significance in analyzing the factors affecting the imbibition efficiency.
