With the amount of injecting-polymer wells in Xingnan SS block of Daqing Oilfield increasing gradually, a lot of problems, such as the treatment and use of sewage flowed back from injecting-polymer wells, need to be solved. The concentrations of gelling agent, cross-linking agent, and regulators have been optimized by measuring gelling strength and gelling time. The additives about pH modifier and deoxidizer have been selected. As a result, the formula system of profile control using sewage flowed back from injecting-polymer wells has been formed, realizing reuse of sewage, reaching the goal of improving oil recovery. The research in this paper not only solves the problem of re-injecting sewage flowed back from injecting-polymer wells, making full use of resources, but saves costs, improving economic benefits.
