Abstract

Aspects of the present relate to automated load cell identification. A method is provided. The method generally includes sending, from a load cell to a remote processing system, identification information associated with the load cell; and determining whether the load cell is valid for use during makeup of a threaded connection of a first threaded tubular to a second threaded tubular based on the identification information associated with the load cell. The load cell identification information may include a measurement range of torque values supported by the load cell. The method can include comparing the measurement range of torque values to a job defined range of torque values associated with the makeup of the threaded connection; and determining that the load cell is valid for use based on the comparison. The identification information can be used to detect the load cell type, range, and calibration data before tubular makeup to ensure data quality and safety at work.

Claims (55)

1. A method, comprising:

sending, from a load cell to a remote processing system, identification information associated with the load cell;

determining whether the load cell is valid for use during makeup of a threaded connection of a first threaded tubular to a second threaded tubular based on the identification information associated with the load cell;

engaging threads of the first threaded tubular to threads of the second threaded tubular;

rotating the first threaded tubular relative to the second threaded tubular, thereby making up the threaded connection;

during makeup of the threaded connection:

measuring force data applied to the connection using the load cell; and

sending, from the load cell to the remote processing system, the measured force data, wherein:

sending the measured force data comprises sending the measured force data via a first interface between the load cell and the remote processing system; and

sending the identification information comprises sending the identification information via a second interface between the load cell and the remote processing system;

calculating, at the remote processing system, torque applied to the connection based on the force data and the identification information associated with the load cell; and

evaluating the threaded connection based, at least in part, on the calculated torque.

2. The method of claim 1 , wherein:

the load cell identification information includes a measurement range of torque values supported by the load cell; and

determining the load cell is valid for use during the makeup of the threaded connection comprises:

comparing the measurement range of torque values to a job defined range of torque values associated with the makeup of the threaded connection; and

determining that the load cell is valid for use based on the comparison.

3. The method of claim 1 , wherein:

the first interface comprises a 4 . . . 20 mA interface; and

the second interface comprises a serial interface.

4. The method of claim 1 , further comprising:

receiving, at the load cell, a request from the remote processing system for the identification information, wherein the identification information is sent in response to the request.

5. The method of claim 1 , further comprising:

sending the force data and identification information to a client of the remote processing system, wherein the evaluating is performed by the client.

6. The method of claim 1 , wherein the identification information comprises at least one of: an identification of the load cell, a type of the load cell, a force measurement range of the load cell, a measurement accuracy of the load cell, a manufacturing date of the load cell, a serial number of the load cell, or calibration information associated with the load cell.

7. A tubular makeup system, comprising:

a load cell;

a remote processing system in communication with the load cell, wherein:

the load cell is configured to send identification information associated with the load cell to the remote processing system; and

the remote processing system is configured to determine whether the load cell is valid for use during makeup of a threaded connection of a first threaded tubular to a second threaded tubular based on the identification information associated with the load cell;

a power drive operable to rotate the first threaded tubular relative to the second threaded tubular thereby making up the threaded connection, wherein:

the load cell is configured to, during makeup of the threaded connection:

measure force data applied to the threaded connection; and

send, to the remote processing system, the measured force data; and

the remote processing system is further configured to:

calculate torque applied to the threaded connection based on the force data and the identification information associated with the load cell; and

evaluate the threaded connection based, at least in part, on the calculated torque; and

a first interface and a second interface between the load cell and the remote processing system, wherein the load cell is configured to:

send the measured force data via the first interface; and

send the identification information via the second interface.

8. The tubular makeup system of claim 7 , wherein:

the load cell identification information includes a measurement range of torque values supported by the load cell; and

the remote processing system is configured to:

compare the measurement range of torque values to a job defined range of torque values associated with the makeup of the threaded connection; and

determine that the load cell is valid for use based on the comparison.

9. The tubular makeup system of claim 7 , wherein:

the first interface comprises a 4 . . . 20 mA interface; and

the second interface comprises a serial interface.

10. The tubular makeup system of claim 7 , wherein the load cell is further configured to:

receive a request from the remote processing system for the identification information; and

send the identification information in response to the request.

11. The tubular makeup system of claim 7 , wherein the remote processing system is further configures to:

send the force data and identification information to a client of the remote processing system; and

evaluate the threaded connection at the client.

12. The tubular makeup system of claim 7 , wherein the identification information comprises at least one of: an identification of the load cell, a type of the load cell, a measurement range of the load cell, a measurement accuracy of the load cell, a manufacturing date of the load cell, a serial number of the load cell, or calibration information associated with the load cell.
