Pressure Response of Polymer Flooding Reservoir by Considering Diffusion and Conduction Behaviors

摘要

A polymer solution is classified as non-Newtonian Fluid. The results of pressure data analysis for polymer flooding reservoirs would be inaccurate when generalized using non-Newtonian fluid flow models, which treat polymer solution as power law fluid. To improve analysis results, a study to create new pressure interpretation models for polymer flooding reservoirs is needed. First, this study presents a new viscosity model by considering diffusion and conduction. Then the model is applied to set up a new model of an injection well located at an infinite polymer flooding reservoir. The modeling solutions have been prepared through numerical iterations. An extended study has been done about the characteristics of the new pressure response curves.
