ABSTRACT:
A sucker rod guide for use in a string of sucker rods reciprocated in tubing, the guide being formed of an elongated cylindrical member having female threaded recesses at the upper and lower ends for attachment to sucker rods and having a plurality of spaced apart parallel sided slots extending through the member in planes of the cylindrical axis, each slot having two wheels rotatably mounted therein on opposite sides of the tubular axis, the wheels being of a diameter less than the diameter of the member and being positioned to contact the interior wall of tubing on opposite sides of the member. The rotational position of adjacent slots are displaced so that the member includes sufficient wheels to keep the body of the member out of contact with tubing and thereby reduce the possibility of the sucker rods sliding against the interior tubing wall.
