Theory and application of numerical simulation of permeation fluid mechanics is discussed about the polymer--black oil (water, oil and gas) in this paper. In view of petroleum geology, geochemistry, computational mechanics of flow and computer technology, the mechanics model of three-phase flow (water, oil and gas) of the polymer is presented firstly, then a numerical algorithm consisting of a full implicit program, and an implicit computation for the pressure and an explicit computation for the concentration is given by structuring an upstream sequence and an iterative algorithm of implicit fined upwind fractional step finite difference to solve the pressure equation, the concentration equation and the saturation of chemical substance components. A type of software applicable in major industries has been made in consideration of ten-meters steps, hundreds of thousands nodes and tens of years and high accuracy and the application has been carried out successfully in analysis and simulation of major oil-fields extraction such as Daqing Oilfield, Shengli Oilfield and Dagang Oilfield and others, which gives rise to outstanding economic and social benefits. A precise analysis is given for a simplified model and an idea is presented to solve this international famous problem.
