ABSTRACT:
A field-installable rod guide firmly grasps the sucker rod to which it is attached and reduces fluid friction to axial movement of the rod guide. The rod guide includes one or more channels for fluid to flow by the guide through straight or helical vanes. An axial access channel which permits application of the rod guide onto a sucker rod has a wide, tapered mouth to minimize the length of time during which the guide is stretched during installation. Recognizing that some stretch is inevitable in the guide at the point opposite the axial access channel, more rod guide material is placed at this point of greater stretch. In a preferred embodiment of the present invention, the rod guide stock from which the rod guide is machined is extruded to form the desired vanes as well as a non-circular "rod hole."This way, a "dual-radius" hole is enabled. The dual-radius hole narrows the gripping radius of the guide to solidly grasp the rod and eliminate slipping of the guide on the rod.
