Abstract

An electrical submersible well pump (ESP) has a motor electrical connector mounted to an exterior of the motor. A motor sensor connects to an interior side of the motor electrical connector. Seal first and second electrical connectors mount to an exterior of a seal/motor adapter. A seal internal wire within the seal section electrically connects interior sides of the seal first and second electrical connectors together. An external motor jumper wire extends alongside the motor between the motor electrical connector and the seal first electrical connector. A pump electrical connector mounts to an exterior of a pump/seal adapter and connects to a pump sensor within the pump. An external seal jumper wire connects between the seal second electrical connector and the pump electrical connector.

First claim

The invention claimed is:

1. An electrical submersible well pump (ESP) for installation in a well, comprising:
a motor, a seal section and a pump;
a motor electrical connector mounted to an exterior of the motor;
a motor sensor in an interior of the motor and connected to an interior side of the motor electrical connector;
a seal/motor adapter on an end of the seal section, the seal/motor adapter having a threaded arrangement for connecting the seal section to the motor;
seal first and second electrical connectors mounted to an exterior of the seal/motor adapter, each of the seal first and second electrical connectors having an exterior side and an interior side;
a seal internal wire within the seal section that electrically connects the interior sides of the seal first and second electrical connectors together;
an external motor jumper wire having one end electrically connected to an exterior side of the motor electrical connector, the motor jumper wire extending alongside the motor and having another end connected to the exterior side of the seal first electrical connector;
a pump/seal adapter on an end of the pump, the pump/seal adapter having a threaded arrangement for connecting the pump to the seal section;
a pump electrical connector mounted to an exterior of the pump/seal adapter, the pump electrical connector having an exterior side and an interior side;
a pump sensor within an interior of the pump and electrically connected to the interior side of the pump electrical connector;
an external seal jumper wire having one end electrically connected to the exterior side of the seal second electrical connector, the seal jumper wire extending alongside the seal section and having an opposite end connected to the exterior side of the pump electrical connector; and wherein
the motor sensor and the pump sensor are linked together through the motor jumper wire and the seal section jumper wire.

2. The ESP according to claim 1 , further comprising:
a controller for placement adjacent a wellhead of a well in which the ESP is installed, the controller being electrically connected with the motor sensor and the pump sensor for supplying power to and addressing the motor sensor and the pump sensor.

3. The ESP according to claim 1 , further comprising:
a slip ring arrangement located between the seal first and second electrical connectors and the internal wire in the seal section that enables the seal/motor adapter to be secured to the seal section by rotation without twisting the seal internal wire.

4. The ESP according to claim 1 , wherein the seal/motor adapter comprises:
an adapter body configured for connection between the motor and the seal section;
first and second electrical annular contacts mounted to the adapter body, the first and second annular contacts being concentric with a longitudinal axis of the adapter body and one encircled by the other, one of the first and second annular contacts being electrically connected with the interior side of the seal first electrical connector, and the other of the first and second annular contacts being electrically connected with the interior side of the seal second electrical connector;
an insert member that engages the adapter body and has threads that secure by rotation of the insert member to threads within the seal section; and
third and fourth annular contacts on the insert member, one encircled by the other, each of the third and fourth annular contacts engaging one of the first and second annular contacts when the insert member engages the adapter body, one of the third and fourth annular contacts being electrically connected to one end of the internal wire in the seal section, and the other of the third and fourth annular contacts being electrically connected to the other end of the internal wire in the seal section.

5. The ESP according to claim 1 , further comprising:
a power cable extending to the motor from an upper end of a well in which the ESP is installed, the power cable having three power conductors for supplying three phase power to the motor;
at least two supplemental power wires connected to lower ends of the power conductors;
a supplemental power supply connected to the supplemental power wires; and
at least one electronic device mounted in either the motor, the seal section or the pump for performing a function other than sensing, the electronic device being powered by the supplemental power supply.

6. The ESP according to claim 1 , further comprising:
a seal sensor electrically connected into the seal internal wire and located within the seal section.

7. An electrical submersible well pump (ESP) for installation in a well, comprising:
a motor, a seal section and a pump;
a motor adapter on a lower end of the motor;
a motor electrical connector mounted to an exterior of the motor adapter;
a motor sensor in an interior of the motor and connected to an interior side of the motor electrical connector;
a seal/motor adapter on an end of the seal section for connecting the seal section to the motor;
seal first and second electrical connectors mounted to an exterior of the seal/motor adapter, each of the seal first and second electrical connectors having an exterior side and an interior side;
a seal internal wire within the seal section that electrically connects the interior sides of the seal first and second seal electrical connectors together;
a seal sensor electrically connected into the seal internal wire;
an external motor jumper wire having one end electrically connected to the exterior side of the motor electrical connector, the motor jumper wire extending alongside the motor and having another end connected to the exterior side of the seal first electrical connector;
a pump/seal adapter on an intake end of the pump for connecting the pump to the seal section;
pump intake first and second electrical connectors mounted to an exterior of the pump/seal adapter, each of the pump intake electrical connectors having an exterior side and an interior side;
a pump intake internal wire within an interior of the pump and electrically connected between the pump intake first and second electrical connectors;
a pump intake sensor within an interior of the pump and electrically connected into the pump intake internal wire;
a pump discharge adapter at an upper end of the pump for connecting the pump to production tubing;
a pump discharge electrical connector mounted to the pump discharge adapter, the pump discharge electrical connector having an exterior side and an interior side;
a pump discharge sensor connected to the interior side of the pump discharge electrical connector;
an external pump jumper wire having one end electrically connected to the exterior side of the pump intake second electrical connector, the pump jumper wire extending alongside the pump and having an opposite end connected to the exterior side of the pump discharge electrical connector;
a controller for placement at an upper end of a well in which the ESP is installed; and wherein
the motor sensor and the pump intake and discharge sensors are electrically linked together and to the controller via the motor jumper wire, the seal section jumper wire, and the pump jumper wire.

8. The ESP according to claim 7 , further comprising:
a slip ring arrangement located between the seal first and second electrical connectors and the seal interior wire that enables the seal/motor adapter to be secured to the seal section by rotation without twisting the seal internal wire.
