Abstract

Abstract:

Considering the absorbing factor and inaccessible pore,a five-spot well pattern model of polymer flooding was built on the base of polymer flooding mechanism analysis.By applying the stream tube method,the areal two-dimensional model was simplified to several one-dimensional displacement models,and a one-dimensional mathematical model of polymer flooding was established.On the basis of frontal displacement theory,the whole process of two-dimensional polymer flooding was simulated by superimposing the displacement performance in each stream tube on the five-spot well pattern.This calculation process was compiled into the VBA software to map the relation between the sweep efficiency and mobility ratios under different water cut conditions are draw,thus providing a theoretical criteria for the polymer solution viscosity preparation when performing IOR through polymer flooding.Comparison between the dynamic parameters with the experimental results shows a good consistency.The advantages of the stream tube model set up in this paper are as follo-wing:less input parameters,quick calculation,well-adapting,and no dispersion effect of numerical simulation as in the traditional rectangular grid.Therefore,this method offers an effective tool for the early selection for polymer flooding and reservoir dynamic management.
