Water Saturation Model Optimization after Polymer Flooding

Abstract:

In this paper, the conducting model which is more suitable to describe the reservoir in the process of polymer flooding was selected, according to the reservoir properties. Based on the polymer solution conductance laws and the polymer flooding rock resistivity experiments, by injecting various types of polymers and water with different salinities, the rock resistivity change rule was studied. The change rule of the Archie model parameters in the polymer flooding process was analyzed and the accuracy of the dual water model was analyzed by means of the Litho-electric experiment data. On the basis of rock physical property analysis data, combined with the actual logging rules, the parameters interpretation model of porosity, permeability, irreducible water saturation and shale content were established. Using the core analyze data to contrast the practical application effect of the interpretation model, the result show that, the conclusion of the model corresponds to reality.
