Abstract

In this paper, according to actual condition of this oil field, a suitable polymer will be designed and built, then, its optimum composition with least amount of additives, best thermal resistance property, resistant to salt and acid and long life time will be determined using rheological tests as a standard method to specify polymer gel properties. Finally, performance of this optimized polymer gel will tested experimentally using several cores of this sandstone reservoir. Rheological properties of polymer gel and its relationship to reservoir rock permeability will be investigated. For this purpose, a set of experimental tests based on rheological, swelling and core flooding tests on sandstones will be designed. So, by deriving mathematical relationships, effect of concentration and type of polymer and ratio of networking factor concentration to polymer on total visco-elastic properties and three dimensional network parameters of polymer gel will be stated.
