| This paper presents a three-dimension three-phase(water phase, oil phase, gas phase)five-component(oil, water, gas, polymer, effcetive salt ion)mathematical model on the basis of integrated survey for the moment wide-used polymer drive and cross-linked polymer drive software and develops a numerical simulation software that can run on personal computer.This model takes gravitation, capillary force, the compressibility of porosity and rock into consideration, and describes the physical-chemical phenomena of salt-resistant polymer drive(inaccessible pore volumes of polymer, adsorption and retention, diffusion, convection, resistance coefficient, residual resistance factor, permeability reduction, shearing factor).Through the comparison between VIP, Eclipse, Grand software and this software we have found that our method has a satisfactory result, and the error is in the allowable range. By using of this simulator we analyse the influence of some factors and gain the corresponding conclusions that have certain theoretical meaning and reference value. |
