HYDRAULIC ASSIST DEPLOYMENT SYSTEM FOR ARTIFICIAL LIFT SYSTEMS AND METHODS FOR USING THE SAME |
摘要 |
A well conveyance system couples to an uphole end of an artificial lift system and operates to push the artificial lift system through a tubing string for deployment in a wellbore. The well conveyance system includes a wellbore tractor adapted to push the artificial lift system through the tubing string and a swab cup assembly having a swab cup and a perforated nipple extending therethrough. The perforated nipple includes a nipple passage allowing for fluid flow from an area downhole from the swab cup to an area uphole from the swab cup when the wellbore tractor operates. A valve selectively blocks the perforated nipple to permit a hydraulic pressure to be applied to the tubing string uphole of the swab cup, exerting a downhole force on the swab cup to aid in deployment of the artificial lift system.
