Abstract

Se provee una guía de varilla para ser utilizada en una sarta de varillas rotativas (12) que acciona una bomba de cavidad progresiva (14) para bombear los fluidos de fondo de pozo a través de la sarta de tubería (16) a la superficie. La guía de varilla incluye un manguito de rotor (20) fijado a la sarta de varillas. Un manguito de estator (40) se dispone sobre el manguito de rotor, y posee un cuerpo de manguito (42) de una configuracion en general circular con extremos circunferenciales opuestos (44, 46) separables para colocar el manguito de estator sobre el manguito de rotor. Una pluralidad de nervios (48) se extiende hacia el exterior desde el cuerpo del manguito de estator. Un extremo circunferencial del manguito de estator posee un elemento de agarre (52), y un extremo circunferencial opuesto del manguito de estator posee una cavidad de recepcion (54) para receptar al menos una porcion del elemento de agarre. Los extremos circunferenciales del manguito de estator están conectados por el elemento de agarre y la cavidad de recepcion.A rod guide is provided for use in a rotary rod string (12) that drives a progressive cavity pump (14) to pump downhole fluids through the pipe string (16) to the surface. The rod guide includes a rotor sleeve (20) attached to the rod string. A stator sleeve (40) is arranged on the rotor sleeve, and has a sleeve body (42) of a generally circular configuration with opposing circumferential ends (44, 46) separable to place the stator sleeve on the sleeve of rotor. A plurality of ribs (48) extends outwardly from the body of the stator sleeve. A circumferential end of the stator sleeve has a gripping element (52), and an opposite circumferential end of the stator sleeve has a receiving cavity (54) for receiving at least a portion of the gripping element. The circumferential ends of the stator sleeve are connected by the gripping element and the receiving cavity.
