Abstract:

A thermal polymer displacement method is presented to used in the heavy oil reservoirs which had been displaced by thermal method.A three dimentional,three phases,four components,non isothermal flow model has been formulated to simulate thermal polymer process.The model incorporates process variables which include diffusion,adsorption,vicosity,relative permeability and so on.In solving this model with finite different method,the space derivatives in concentration and energy equations are treated with a second order approximation,and the non linear coefficients are pseudo linearlized.The software is made to simulate the thermal polymer process.This model was tested by an example and the results are satisfied.It is feasible to use thermal polymer displacement in reservoirs which had been displaced by thermal method.
