In Dagang Oilfield No.4 Plant, the effect of liquid-air injection jet synergistic technology applied in the two wells of plate 808-7 and port 365-1 was obvious. The average pump efficiency increased by 24.47% and the daily oil output increased by 5.6t. The synergistic technique is based on controlling the hydrodynamic characteristics of oil and gas wells, especially in flow regimes, flow patterns, flow rates, and flow pressures, based on the principle that the hydraulic characteristics of multiphase flows (liquids and gases) are most influenced by the fluid regime The favorable bubble flow, which is well distributed in the liquid, can be achieved with this technique, which significantly reduces the static pressure loss by reducing the overall density of the lifting fluid By reducing the high velocity gas in the casing and the relatively low velocity liquid Between the friction can significantly reduce the dynamic pressure loss and improve the pump full coefficient, to achieve the purpose of improving pump efficiency Oil Production Plant in the two oil gas wells affected by the application of liquid gas injection jet flow synergistic technology, gas-liquid ratio From 132.36m3 / t down to 77.32m3 / t, to achieve the purpose of reducing gas, improve pump efficiency, oil well stimulation.
