Abstract

The binary system flooding test site in block J16 has serious polymer gather phenomenon, To solve this problem, applying the way of injecting cationic profile control and water shutoff agent from producing well which provide a polymer gather layer plugging so as to reduce polymer concentration in producing well. The results of physical simulation experiments in laboratory showed that all the selected profile control and water shutoff agent can react with the polymer, which can effectively decrease polymer concentration, delay the time when the polymer appeared and when the peak of the polymer concentration came; This measure can also improve the initial injecting pressure of polymer without reaction product washed out from the core; To the same profile control and water shutoff agent, the larger concentration and injection rate made the injecting pressure get larger, the time when the polymer appeared get longer and the concentration of the polymer in production well became lower; The concentration of profile control and water shutoff agent should be higher than 0.6%, the injected slug should be more than 0.5 PV.
