The Variation Characteristics Analysis of Polymer Concentration in Polymer Flooding

Since the polymer industry promotion block production, with the development of polymer flooding from the main oil layer to the second type of oil gradually expanded, polymer flooding the whole process of the development of the law is also gradually deepening, gathering concentration is the analysis of polymer. The results show that there is a certain variation rule of the concentration of polymer in the whole process of polymer flooding development through the accumulation of a large number of gathering concentration data. In this paper, the characteristics of polymer flooding concentration, comprehensive water cut down rate, comprehensive water cut down, water cutoff duration and subsequent water flooding concentration and comprehensive water content are expounded, as well as the influence of polymer concentration and the changing trend of the concentration of polymer flooding in the development process was analyzed. In-depth study and grasp the concentration of mining concentration, can further improve the overall effect of polymer flooding development, but also for the follow-up injection block, especially the second type of polymer flooding development has great significance.
