DOWNHOLE ELECTRICAL COUPLER FOR ELECTRICALLY OPERATED WELLBORE PUMPS AND THE LIKE

摘要

An electrical coupling system for use in a wellbore that enables insertion and removal of an electrically operated device in a wellbore includes an electrical receptacle mounted at a selected axial position along a tubing disposed in the wellbore. The receptacle includes at least one insulated electrical conductor coupled to an electrical contact inside the receptacle and extending to the well surface. An electrical coupler is disposed on an exterior of the electrically operated device. The coupler includes at least one electrical contact disposed proximate the receptacle contact when the coupler is mated to the receptacle. The coupler including at least one flow passage enabling wellbore fluid flow from below the coupler to an annular space between the electrically operated device and an interior of the tubing.
