It is Suitable for the Development and Application of Polymer Flooding Viscosity-Reducing and Oil-Increasing Integrated Device

Due to the high viscosity of produced fluid, especially the high concentration polymer, the fluid flow resistance greatly affects the production. At the same time, the plunger downward resistance increases, the rod bending deformation is obvious, and the rod and tube bias wear range is increased. Therefore, an integrated visity-reducing and oil-increasing device is developed, which is mainly composed of gas-liquid separator, magnetic field processor, acoustic wave generator and check valve. The device has physical effects on the flowing liquid, which can reduce the viscosity of well fluid, realize gas-liquid separation and increase liquid fluidity. Field test results show that the viscosion-reducing and oil-increasing integrated device can reduce the liquid viscosity and gas influence of the poly flooding pumping unit, and increase the liquid production. Thirteen test Wells were carried out in the field. After the measure, the average daily liquid production increased by 3.1 m3, the average pump efficiency increased by 4.13% points, and the average pump detection period extended by 126 days. With the continuous improvement and application of the integrated device of viscosity reduction and oil increase, it has considerable economic benefits for the efficient exploitation of polymer flooding pumping unit.
