THE INFLUENCE DEGREE OF DIFFERENT FACTORS ON THE EFFECTIVENESS OF POLYMER FLOODING

doi:10.3863/j.issn.1000-

Abstract

Abstract:

The displacement effectiveness of polymer flooding is influenced by numerous factors and different factor plays different role in controlling polymer flooding process.In this paper,the singlelayer and multilayer reservoir geological model are developed to investigate the influence of twelve parameters,such as polymer performance，injectionproduction parameters and large channel etc.,on the effectiveness of polymer flooding by the method of numerical simulation.The mathematical statistics method is used to analyze the different degree of effectiveness caused by various factors.The key factors controlling the displacement effectiveness of polymer flooding are obtained,and some suggestions are presented to ensure the effectiveness of polymer flooding.

Key words: polymer flooding, enhanced oil recovery, influence factor, large channel, influence degree 
