ELECTRICAL CONNECTION SYSTEM WITH BALANCED WELL BACKGROUND PRESSURE, AND, ISOLATION METHOD OF A LINE IN A UNDERGROUND WELL FROM WATER FLUID IN THE WELL '

摘要

well system, method of isolating a line in an underground well from well fluid in the well. downhole connections with balanced pressure. A well system includes a well tool, a conduit assembly connected with the well tool, the conduit assembly including a conduit and a line positioned within the conduit, the line being connected with the well tool for operation of the well tool. well, and a device for equalizing pressure between an interior and an exterior of the duct, the device being positioned at the bottom of the well. A method of isolating a line in an underground well from well fluids in the well includes the steps of: connecting a conduit assembly with a device for equalizing pressure between an interior and an exterior of the conduit assembly, the conduit assembly including a line installed within a conduit; and position the duct assembly and pressure equalization device in the well.
