    • A method of transmitting a fluid into an oil well bore including the steps of providing a frame supporting a vessel, the vessel having an interior, upper and lower end portions, a conically shaped side wall, and an outlet for discharging the fluid from the vessel. Further including the steps of adding a viscous polymeric material to the vessel interior, placing a discharge pipe having a vertical section below the vessel wherein the discharge pipe is in communication with the outlet, placing a positive displacement pump within the discharge pipe wherein the pump transmits fluid from the outlet into the discharge pipe downstream of the vertical pipe section, and selectively transmitting fluid to either the vessel interior (for recirculating) or into the well. Air is added to the discharge flow line downstream of the pump. Preferably, the vessel contains a flexible bladder/bag that holds the material to be pumped.
    • 一种将流体传送到油井的方法,包括以下步骤:提供支撑容器的框架,所述容器具有内部,上下端部,圆锥形侧壁和用于从容器排出流体的出口 。 还包括以下步骤:将粘性聚合材料添加到容器内部,将排放管放置在容器下方具有垂直部分的排放管,其中排放管与出口连通,将排出管中的容积泵放置在排出管内, 流体从出口进入垂直管段下游的排放管,并且选择性地将流体传送到容器内部(用于再循环)或进入井中。 空气被添加到泵的下游的排出流动管线。 优选地,容器包含保持待泵送材料的柔性气囊/袋。
