Abstract
A cable system for use downhole includes a connector assembly having a body and a bore formed therethrough; a conductor disposed through the bore of the connector assembly; and a first insulation layer disposed around the conductor. An insulator tube is disposed around the conductor and has an end attached to the first insulation layer. The insulator tube may be made of a thermoplastic material. A graphite containing sealing member is disposed in the bore and disposed between the insulator tube and the body of the connector assembly.
Claims21
A cable system for use downhole, comprising:
- a connector assembly having a body and a bore formed therethrough;
- a conductor having a portion disposed in the bore of the connector assembly;
- an insulator cap having a cap portion, wherein the cap portion is disposed in the bore and disposed around a portion of the conductor;
- a graphite containing sealing member disposed in the bore and disposed between the portion of the conductor disposed in the bore and the body of the connector assembly;
- and
- a fastener pressing against the graphite sealing member and disposed between the cap portion and the graphite containing sealing member, wherein the fastener has a threaded connection to the body to retain the graphite containing sealing member in the bore.
A submersible pumping system for use downhole, comprising:
- a motor;
- a pump powered by the motor;
- a tubing connected to the pump;
- and
- a cable disposed along the tubing and configured to provide power to the motor, the cable comprising:
- a connector assembly having a body and a bore formed therethrough;
- a conductor having a portion disposed in the bore of the connector assembly;
- an insulator cap having a cap portion, wherein the cap portion is disposed in the bore and disposed around a portion of the conductor;
- a graphite containing sealing member disposed in the bore and disposed between the portion of the conductor disposed in the bore and the body of the connector assembly;
- and
- a fastener pressing against the graphite containing sealing member and disposed between the cap portion and the graphite containing sealing member, wherein the fastener has a threaded connection to the body to retain the graphite containing sealing member in the bore.
A cable system for use downhole, comprising:
- a connector assembly having a body and a bore formed therethrough;
- a restriction extending from the body of the connector assembly and disposed in the bore of the connector assembly;
- a conductor having a portion disposed in the bore of the connector assembly;
- an insulator cap having a cap portion, wherein the cap portion is disposed in the bore and disposed around a portion of the conductor;
- a graphite containing sealing member disposed in the bore of the connector assembly and disposed between the portion of the conductor disposed in the bore and the body of the connector assembly;
- and
- a fastener pressing against the graphite containing sealing member and disposed between the cap portion and the graphite containing sealing member, wherein the fastener has a threaded connection to the body to retain the graphite containing sealing member pressed against the restriction.
