20120260990 | Vertical flow cage and method of use - The present invention is centralizing vertical flow cage attachable to a subsurface pump in a downhole recovery application, and method of use. In one embodiment, the vertical flow cage is defined as comprising a hollowed, centralizing cone portion having at least one spiral vein formed in the cone's surface. In another embodiment, the centralizing cone includes a ledge having at least one discharge hole disposed thereon, with each discharge hole being selectively located above each vein. Each discharge hole is formed through the centralizing cone so that each hole formed is in fluid communication with the hollow interior portion of the centralizing cone. In this regard, during the pump process upstroke, any fluid below and outside of the centralizing cone will be forced vertically upwards through each vein. This fluid flow will be assisted by the flow of fluid through each hole, as any fluid within the hollow portion will flow upward and through each hole, thereby providing a synergistic vertical fluid flow effect. | 10-18-2012 |
