Electronic control system for a tubular handling tool
An electronic control system comprises a first tubular handling tool, a sensor, and a controller. The controller is configured to control actuation of the first tubular handling tool in response to an electronic signal received from the sensor that corresponds to an operational characteristic of the first tubular handling tool. The electronic control system functions as an electronic interlock system to prevent mishandling of a tubular. A method of controlling a tubular handling tool comprises measuring an operational characteristic of the tubular handling tool, communicating the operational characteristic to a controller in the form of an electronic signal, and using the controller to control actuation of the tubular handling tool in response to the measured operational characteristic.
1. A tubular handling system, comprising:
a tubular handling tool;
a sensor configured to measure an operational characteristic of the tubular handling tool, wherein the operational characteristic includes a load supported by the tubular handling tool;
an electronic control system in communication with the sensor; and
a rig winch system in communication with the electronic control system, wherein the electronic control system is operable to automatically control the rig winch system to raise or lower the tubular handing tool to a position to make up or break out a tubular or tubular string when the load that is measured by the sensor corresponds to a pre-determined load and is communicated to the electronic control system, and wherein the electronic control system is configured to override or prevent a command by an operator to initiate actuation of the rig winch system.
2. The system of claim 1 , wherein the operational characteristic further includes a position of the tubular handling tool, and wherein the sensor includes at least one of a load cell, a strain gauge, and a position sensor.
3. The system of claim 1 , wherein the rig winch system includes a drum assembly, a motor assembly, and a brake assembly, and further comprising one or more rig winch sensors coupled to at least one of the drum, motor, and brake assemblies, wherein the one or more rig winch sensors are in communication with the electronic control system, and wherein the electronic control system is operable to control operation of at least one of the drum, motor, and brake assemblies.
4. The system of claim 1 , wherein the electronic control system is operable to prevent actuation of the rig winch system in response to the load that is measured by the sensor and communicated to the electronic control system.
5. The system of claim 1 , wherein the electronic control system is operable to send a signal to the operator of the rig winch system corresponding to the operational characteristic of the tubular handling tool.
6. The system of claim 1 , wherein the electronic control system is configured to override or prevent the command by the operator to initiate actuation of the rig winch system if certain pre-programmed conditions are not met.
7. The system of claim 1 , wherein the electronic control system is configured to override or prevent the command by the operator to initiate actuation of the rig winch system if the electronic control system is receiving a signal from the sensor that is not in accordance with certain pre-determined conditions with respect to the tubular handling tool.
8. The system of claim 1 , wherein the electronic control system is configured to allow the command by the operator to initiate actuation of the rig winch system if certain pre-programmed conditions are not met.
9. The system of claim 1 , wherein the electronic control system is configured to allow the command by the operator to initiate actuation of the rig winch system if the electronic control system is receiving a signal from the sensor that is not in accordance with certain pre-determined conditions with respect to the tubular handling tool.
10. The system of claim 1 , wherein the pre-determined load corresponds to the weight of the tubular handling tool when not supporting any tubular or tubular string.
11. The system of claim 1 , wherein the pre-determined load corresponds to the weight of the tubular handling tool plus the weight of the tubular string when supporting the tubular string.
12. The system of claim 1 , wherein the position corresponds to a position that the tubular handling tool is moved to engage another tubular that is to be made up to the tubular string.
13. The system of claim 1 , wherein the position corresponds to a position that the tubular handling tool is moved to raise the tubular string after make up of a tubular to the tubular string.
14. The system of claim 1 , wherein the position corresponds to a position that the tubular handling tool is moved to raise the tubular after break out from the tubular string.
15. A tubular handling system, comprising:
a tubular handling tool;
a sensor configured to measure a load supported by the tubular handling tool;
an electronic control system in communication with the sensor; and
a rig winch system in communication with the electronic control system, wherein the electronic control system is operable to automatically control the rig winch system to raise or lower the tubular handing tool to a position to make up or break out a tubular or tubular string when the load that is measure by the sensor corresponds to a pre-determined load and is communicated to the electronic control system.
16. The system of claim 15 , wherein the electronic control system is operable to prevent actuation of the rig winch system based on the load that is measured by the sensor and communicated to the electronic control system.
17. The system of claim 15 , wherein the electronic control system is configured to override or prevent the command by the operator to initiate actuation of the rig winch system if the electronic control system is receiving a load measurement from the sensor that is not in accordance with certain pre-determined conditions with respect to the tubular handling tool.
18. The system of claim 15 , wherein the pre-determined load corresponds to the weight of the tubular handling tool when not supporting any tubular or tubular string.
19. The system of claim 15 , wherein the pre-determined load corresponds to the weight of the tubular handling tool plus the weight of the tubular string when supporting the tubular string.
20. The system of claim 15 , wherein the electronic control system is operable to automatically control the rig winch system to raise the tubular handing tool to the position to engage another tubular to make up to the tubular string when the load that is measured by the sensor corresponds to the pre-determined load and is communicated to the electronic control system.
21. The system of claim 15 , wherein the position corresponds to a position that the tubular handling tool is moved to engage another tubular that is to be made up to the tubular string.
22. The system of claim 15 , wherein the position corresponds to a position that the tubular handling tool is moved to raise the tubular string after make up of a tubular to the tubular string.
23. The system of claim 15 , wherein the position corresponds to a position that the tubular handling tool is moved to raise the tubular after break out from the tubular string.
