Abstract

An electrically-powered service rig utilizes an engine-driven generator to power a propulsion system, a drawworks system and a sandline system, all mounted on a single mobile platform. The rig utilizes lightweight permanent magnet motors to enable integration of the systems onto a single mobile platform which meets transport regulations. The rig's power plant is capable of powering other on-site equipment such as mud pump motors through use of umbilicals connected to the engine-driven generator.

Claims (18)

1. An electrically-powered well service rig comprising:
a mobile platform for transporting the service rig;

an engine-driven generator carried by the platform for generating AC power;

a propulsion system carried by the platform for transporting the mobile platform service rig having a collapsible mast thereon, the propulsion system having a permanent magnet propulsion motor for driving the platform, a propulsion variable frequency drive (VFD) connected between the generator and the propulsion motor;

a drawworks system carried by the platform and having blocks adapted for raising and lowering a plurality of tubulars into and out of a wellbore, the drawworks system having at least a drawworks drum having drawworks cable wound thereon and rotatably driven by a permanent magnet drawworks motor; a drawworks VFD connected between the generator and the drawworks motor;

a sandline system carried by the platform and adapted for raising and lowering a sandline tool into and out of a wellbore, the sandline system having at least a sandline drum having sandline cable wound thereon and rotatably driven by a permanent magnet sandline motor; a sandline VFD
connected between the generator and the sandline motor; and one or more programmable logic controllers (PLC) carried by the platform for outputting speed setpoints to the propulsion VFD, the drawworks VFD; and the sandline VFD.
2. The electrically-powered well service rig of claim 1 wherein the propulsion system further comprises:

at least a semi-automatic manual transmission; and a transmission PLC for controlling the transmission, wherein the propulsion PLC receives a desired road speed signal for forwarding to the transmission PLC;

the transmission PLC communicates speed setpoints to the propulsion PLC for adjusting a motor speed of the propulsion motor to achieve the desired road speed.
3. The electrically-powered well service rig of claim 1 or 2 further comprising an electrical motor braking system for one or more of the propulsion VFD, drawworks VFD and sandline VFD.
4 The electrically-powered well service rig of claim 3 wherein the motor braking system further comprises a dynamic and a regenerative braking system.
5. The electrically-powered well service rig of any one of claims 1 to 4 further comprising a wet multi-disc brake for one or both of the drawworks VFD and sandline VFD.
6. The electrically-powered well service rig of any one of claims 1 to 5 for handling tubulars in and out of a well, the tubulars having one or more flag locations thereon further comprising:

drawworks sensors for establishing measures of the running position of the one or more flag locations and communicating said measures to the drawworks PLC; and one or more target locations representing physical positions on or off the service rig wherein the drawworks PLC reduces the maximum speed setpoint for the drawworks VFD as the flag locations of the tubing are within a window distance of the target location.
7. The electrically-powered well service rig of claim 6 wherein the one or more flag locations are tubing collars of the plurality of tubulars in a production string, and the target locations are at least a rig floor position and crown position.
8. The electrically-powered well service rig of claim 6 wherein the drawworks drum further comprises a drawworks shaft, the drawworks sensors further comprising a drawworks shaft encoder and a block load sensor.
9. The electrically-powered well service rig of any one of claims 1 to 8 for handling a sandline tool into and out of a well, the sandline tool having one or more flag locations thereon further comprising:

sandline sensors for establishing measures of the position of the one or more flag locations and communicating said measures to the sandline PLC; and one or more target locations wherein the sandline PLC reduces the maximum speed setpoint for the sandline VFD as the position of the one or more flag locations of the sandline tool are within a window distance of the target locations.
10. The electrically-powered well service rig of claim 9 wherein the one or more flag locations are the top and bottom of the swabbing tool, and the target locations are a rig floor position and a bottom of the well.
11. The electrically-powered well service rig of claim 9 wherein the sandline drum further comprises a sandline shaft, the sandline sensors further comprising a sandline shaft encoder.
12. The electrically-powered well service rig of claim 6 wherein, the drawworks PLC is programmed for raising and lowering plurality of tubulars having collars into and out of the wellbore wherein the target locations comprise at least a first rig floor position;

a second power tong position; and a third crown position, the drawworks PLC outputs setpoints to the drawworks VFD for reducing the maximum speed setpoint for the drawworks VFD as the position of the collars are within a window distance of the target locations.
13. The electrically-powered well service rig of claim 9 wherein, the sandline PLC is programmed for raising and lowering a sandline tool having a top end and a bottom end into and out of the wellbore wherein the target locations comprise at least a first bottom hole position;

a second wellhead [lubricator] position, and a third crown position, the sandline PLC outputting setpoints to the sandline VFD for reducing the maximum speed setpoint for the sandline VFD as the position of the sandline tool top end and bottom end are within a window distance of the target locations.
14. The electrically-powered well service rig of claim 6 further comprising one or more calibration switches for signaling relative correspondence of a flag location and a target position.
15. The electrically-powered well service rig of claim 9 further comprising one or more calibration switches for signaling relative correspondence of a flag location and a target position.
16 The electrically-powered well service rig of any one of claims 1 to 15 further comprising one or more electrical umbilicals for providing power from the generator for powering on-site apparatus.
17 The electrically-powered well service rig of claim 16 wherein the on-site apparatus comprises an independently transportable electrically-powered mud pump having a mud pump motor operatively connected to the mud pump.
18. The electrically-powered well service rig of claim 16 wherein the one or more electrical umbilicals provide power for hotel loads.
