Title (EN) METHOD AND APPARATUS FOR ALIGNING ROTOR IN STATOR OF A ROD DRIVEN WELL PUMP
(FR) PROCEDE ET APPAREIL D'ALIGNEMENT D'UN ROTOR DANS UN STATOR D'UNE POMPE DE PUITS ACTIONNEE PAR UNE TIGE
Abstract: front page image
(EN)A progressing cavity rod-driven well pump (11) utilizes a tag shoulder (21) above a helical passage (17) of the stator (15). The pump stator is located at the lower end of a string of tubing (25). The tag shoulder is more restrictive than a passage through the tubing. A pump rotor (27) is secured to a string of rods and has a stop (29) located above the rotor. The rotor is lowered on the rods until the stop lands on the tag shoulder. Then the operator lifts the rods and the rotor to accommodate for expected stretch during operation. By removing the rods and rotor, monitoring tools can be lowered through the tag shoulder and stator.
(FR)Une pompe de puits actionnEe par une tige A cavitE progressive (11) utilise un Epaulement (21) au-dessus d'un passage hElicoIdal (17) du stator (15). Le stator de la pompe est situE A l'extrEmitE infErieure d'une sErie de tuyaux (25). L'épaulement est plus restrictif qu'un passage A travers les tuyaux. Un rotor de pompe (27) est maintenu par une sErie de tiges et dispose d'une butEe (29) situEe au-dessus du rotor. Le rotor est abaissE sur les tiges jusqu'a ce que la butEe se pose sur l'épaulement. AprEs cela, l'opErateur relEve les tiges et le rotor pour permettre l'extension prévue pendant le fonctionnemnet. En retirant les tiges et le rotor, il est possible d'abaisser des outils de contrOle A travers l'épaulement et le stator.
