The Simulator of Multiple Crosslinking Polymer Channeling proof Displacement Compositional Model

Polymer displacement is of great importance in tertiary oil recovery. Crosslinking polymer channeling proof displacement technique was also developed in past several years. In this paper, a compositional model of multiple crosslinking polymer channeling proof displacement is established according to laboratory simulation result, mass conservation law and momentum conservation law. And applying advanced numerial simulation theory, a 3 D 2 phase 7 component model simulator suitable for multiple crosslinking is developed, which provides a theoretical method and a numerial simulation means for the study of the reservoirs with multiple crosslinking polymer channeling proof displacement. The simulator can be used for the study and simulation of various crosslinking polymer channeling proof/polymer displacement, water shutoff and profile control tests in order to put forward a development plan suitable to tested area, and for the fitting of the development process. It can also be used for the simulation of various combination and cross of multiwell channeling proof,water shutoff and profile control in order to select the best displacement plan suitable to this area, and for the simulation display and prediction of various processes (physicachemical reaction processes and the changing processes of static and dynamic percolation fields)in displacement. In this paper,some problems are also discussed on multiple crosslinking polymer channeling proof and delayed crosslinking polymer channeling proof/polymer displacement.Subject headings
