Determination of Suspension Filtration Parameters from Experimental Data

摘要

The article is devoted to determining the filtration parameters of a polymer-suspension system basedon experimental data on the injection of polymer and suspension into a core sample.A dimensionlessmathematical model of the filtration process based on the law of conservation of mass and Darcy's lawis presented.Dimensionless characteristics of the filtration process(dimensionless effective viscosity anddimensionless parameter that determines the velocity of the polymer slug)are introduced and calculated.According to experimental data,the formation damage coefficient and the filtration coefficient duringsuspension injection were determined,which are in satisfactory agreement with the theories of polymerslug filtration and deep bed migration.
