Modeling operation of a tool in a wellbore

摘要

In modeling operation of a well tool in applying a force to a device in a well, a computing system receives inputs representing a plurality of geometric characteristics of the well tool. The computing system also receives inputs representing a plurality of geometric characteristics of the well. The computing system determines based on the geometric characteristics of the well tool and the well, a predicted reaction force on a portion of the well tool that affects operation of the well tool in applying force to the device. The predicted reaction force is due to contact between a surface associated with the well tool and a surface of the well.

1. A computer-implemented method for modeling operation of a well tool in a well, the method comprising:
receiving, with a computing system, inputs representing a plurality of geometric characteristics of the well tool, the well tool operable to apply a force on a downhole well device by moving through the well relative to the device; receiving, with the computing system, inputs representing a plurality of geometric characteristics of the well; determining, with the computing system, based on the geometric characteristics of the well tool and the well, a predicted reaction force on a portion of the well tool that affects an operation of the well tool in applying the force to the downhole device, the predicted reaction force generated at a contact between a surface associated with the well tool and a surface of the well as the tool moves through the well while applying the force to the downhole device; and comparing the predicted reaction force to a failure force of the well tool to determine a success of the well tool at moving through the well while applying the force to the downhole device.
