Abstract

An electric submersible pump device has a pump and a motor. The motor can be adjacent to the pump. A support member supports the sensor and has a length so that the sensor is located a first distance downhole from a downhole distal end of the motor.

Claims

1. An electric submersible pump device, comprising:

a pump;

an electric motor mechanically connected below the pump;

an electric submersible pump gauge connected below the electric motor, the electric submersible pump gauge comprising a plug sleeve assembly disposed within an opening in an exterior wall of the electric submersible pump gauge, the plug sleeve assembly comprising a plug sleeve and a plug, the plug disposed about an uphole wire such that a portion of the uphole wire is inside of the electric submersible pump gauge;

a support member connected below the electric submersible pump gauge and secured to the electric submersible pump gauge via an adapter;

a sensor case connected to the support member; and

a sensor disposed within a recess on a lateral surface of the sensor case, the sensor comprising at least one selected from a group consisting of;

a temperature sensor, a flow-meter, a vibration sensor and a pressure sensor, wherein the sensor is disposed at a distance from the electric motor that is greater than a longitudinal length of the motor, the sensor being in electric communication with the electric submersible pump gauge via a second wire routed along the support member, through the adapter, and into the electric submersible pump gauge wherein the second wire is in electrical communication with the uphole wire.

2. The electric submersible pump device of claim 1, wherein the support member is a hollow tubular member.

3. The electric submersible pump device of claim 1, wherein the support member is jointed tubing.

4. The electric submersible pump device of claim 1, comprising an adapter, the adapter having a threaded connector portion adapted to attach to the support member, and a connector portion adapted to bolt to a part.

5. The electric submersible pump device of claim 1, wherein the gauge is electrically connected to the motor and has an electrical conduit for connecting to an electrical conduit connected with the sensor;

wherein the electrical conduit connected with the sensor is a wire.

6. The electric submersible pump device of claim 5, wherein a connector portion of an adapter is adapted to bolt to the gauge, wherein the electrical conduit of the gauge can be connected to the electrical conduit from the sensor while the adapter is bolted to the gauge.

7. The electric submersible pump device of claim 1, wherein the support member has a longitudinal length which positions the sensor at least 30 meters from a bottom of the electric motor.

8. The electric submersible pump device of claim 1, wherein the support member is a separate removable part.

9. The electric submersible pump device of claim 1, wherein the support member is selected from a group consisting of:

coiled tubing and cable.

10. An electric submersible pump device, comprising:

a pump;

an electric motor mechanically connected to the pump;

an electric submersible pump gauge connected below the electric motor, the electric submersible pump gauge comprising a plug sleeve assembly disposed within an opening in an exterior wall of the electric submersible pump gauge, the plug sleeve assembly comprising a plug sleeve and a plug, the plug disposed about an uphole wire such that a portion of the uphole wire is inside of the electric submersible pump;

a support member connected to an adapter located below the electric submersible pump gauge;

a sensor case connected to the support member, the sensor case having an inner cavity;

a sensor disposed within the inner cavity of the sensor case; and

a second wire coupling the sensor with the electric submersible pump gauge, the second wire being joined by a connection located in proximity to the adapter between the support member and the gauge to facilitate communicative coupling of the sensor with the gauge and wherein the second wire is in electrical communication with the uphole wire.

11. The electric submersible pump device of claim 10 wherein the electric motor comprises a longitudinal length and wherein the support member comprises a longitudinal length equal to or greater than the longitudinal length of the electric motor.

12. The electric submersible pump device of claim 10 wherein the support member comprises a longitudinal length that positions the sensor at least 30 meters from a bottom of the electric motor.
