    • A method of improving a steam drive wherein high-quality steam is initially injected into a hydrocarbon-bearing formation to initiate a steam drive from an injection well to a production well and then very low-quality steam or water is injected into the formation until the cumulative value of quality of all the injected fluid is reduced to a value between 35 and 45% to maximize the heat utilization of the steam in the formation and improve the sweep efficiency of the steam drive and then adjusting the quality of the steam injected into the formation to a value of between 35 and 45% to continue the steam drive.
    • 一种改进蒸​​汽驱动器的方法,其中最初将高质量蒸汽注入含烃地层以启动从注入井到生产井的蒸汽驱动,然后将非常低质量的蒸汽或水注入地层,直到 所有注入流体的质量的累积值降低到35至45%之间,以最大化地层中蒸汽的热利用率,并提高蒸汽驱动器的扫掠效率,然后调整注入到蒸汽中的蒸汽的质量 形成到35%到45%之间,继续蒸汽驱动。
