In Dagang Oilfield No.4 Factory, the application of liquid-air injection jet synergistic effect in the two wells of plate 808-7 and port 365-1 started to show an obvious effect. The average pump efficiency increased by 24.47% and the daily oil output increased by 5.6t. Hydrogaspiric jet synergistic technologies are based on controlling the hydrodynamic characteristics of oil and gas wells, especially in flow regimes, flow regimes, flow rates, and flow pressures, and are based on the hydraulics of multiphase flows (liquids and gases) The most influential flow principle. With this technique, a favorably good bubble-like flow, which bubbles distribute well in the liquid, can be obtained, significantly reducing the static pressure loss by reducing the overall density of the lifting fluid. By reducing the friction between the high-speed gas and the relatively low-speed liquid in the casing tube, the dynamic pressure loss can be remarkably reduced and the filling coefficient of the oil pump can be increased to improve the pump efficiency. In the two oil wells affected by the gas, the No.4 Oil Production Plant applied the technology of liquid-gas mixing jet to enhance efficiency. The gas-liquid ratio dropped from 132.36m3 / t to 77.32m3 / t, which reduced the gas influence and increased the pumping efficiency. The purpose of increasing production.
