There are great differences in the development status, water flooding degree and pressure maintenance level in the planar areas, especially in the central Du 18 well area where water flooding is serious, the deployment of new wells in the secondary development and the adjustment of injection and production well pattern are basically completed, and it is difficult to improve the development effect by relying solely on water flooding, and it is urgent to change the development mode. In this paper, the development effect of chemical flooding in sand-producing reservoirs is improved by means of fine reservoir research, optimization of formulation system, improvement of process technology and other means, starting from the production of well control sand to stabilize sand, polymer injection in injection wells to maintain viscosity, and improvement of reservoir production.展开更多
