METHOD AND SYSTEM FOR DEPLOYING AN ELECTRICAL SUBMERSIBLE PUMP IN A WELLBORE

摘要

A method for deploying a pump system in a wellbore includes coupling the pump system to one end of a tubing encapsulated cable. The cable is extended into a wellbore drilled through a subsurface fluid producing formation. The tubing encapsulated cable has an outer tube extending substantially continuously from the end thereof connected to the pump system to a surface end of the cable. The outer tube is made from material selected to exclude fluid in the wellbore from an interior of the outer tube. The cable includes at least one electrical conductor disposed inside the outer tube, wherein a rated load current of the at least one electrical conductor is selected such that substantially continuous electrical current drawn by the electrical load device exceeds the rated current of the at least one electrical conductor.

1. A method for deploying an electrical load device in a wellbore, comprising:
electrically and mechanically coupling the electrical load device to a tubing encapsulated cable disposed on a winch; and extending the tubing encapsulated cable and the electrical load device into a wellbore; wherein the tubing encapsulated cable comprises an outer tube which excludes fluid in the wellbore from an interior of the outer tube, the tubing encapsulated cable including at least one electrical conductor disposed inside the outer tube, wherein the electrical load device draws a substantially continuous electrical current greater than a rated current of the at least one electrical conductor.
