ABSTRACT:
An ultra-high molecular weight polyethylene sucker rod guide for mounting on a sucker rod in multiple, spaced units and preventing, or at least minimizing, contact between the sucker rod and the tubing which encloses the sucker rod. In a preferred embodiment the sucker rod guide is characterized by an extruded polyethylene plastic having an ultra-high molecular weight and ultra-high density which exhibits a wet coefficient of friction that is lower than that of metal, to increase the overall pumping efficiency of oil wells. In a most preferred embodiment of the invention, the sucker rod guide is constructed of a self-lubricating, ultra-high molecular weight, ultra-high density, extruded polyethylene bar stock. The sucker rod guide includes a longitudinal, grooved bore which is preferably undersized with respect to the sucker rod upon which the sucker rod guide is mounted and a tapered body slot which communicates with the bore for inserting the sucker rod guide on a sucker rod at a desired location. Multiple units of the sucker rod guide are attached to the sucker rod string in spaced relationship, in order to radially space the sucker rod string from the tubing, lubricate the reciprocating or spinning action of the sucker rod string and prevent or minimize sucker rod and tubing wear. Various sucker rod guides constructed according to this invention are color-coded according to size for quick identification and installation on sucker rods of various diameter.
