发明名称 Rod guide and solids control assembly
摘要 The rod guide and solids control assembly can be mounted on a rod string. The assembly can allow well fluid that contains high solids to pass through the pump under normal operation while eliminating the solids from being swept back into the pump barrel. The assembly can include a body portion coupled to a bristle that extends helically around the body portion. The body portion can be placed on a pump valve rod or hollow valve rod. On an upstroke, the bristles can be locked into place for trapping and lifting the solids. On a downstroke, the bristles can be rotated for leaving the solids higher and away from a pump intake. This can allow the solids to be lifted out of the pump and thereby prevent solids from collecting on a bottom portion of the pump. Multiple assemblies can be incorporated into the sucker rod string.

主权项 1. A rod guide assembly comprising: a top portion; a bottom portion; a body portion positioned between said top portion and said bottom portion, said body portion having: a helical groove formed on said body portion and spiraling vertically along a length of said body portion; anda bristle coupled to said body portion and positioned within said groove, wherein said bristle extends continuously and helically within said groove of said body portion so that said bristle conforms to a spiral shape of said groove, wherein said bristle is adapted to lock into place from an initiation of an upstroke of said rod guide assembly to an end of said upstroke in order to lift and trap solids away from pumped fluid, and wherein said bristle is adapted to generate a corkscrew action through said pumped fluid during a downstroke of said rod guide assembly.
