AI Technical Summary

Technical Problem

Existing drilling rigs have difficulty accurately positioning the drill bit during the drilling process, especially when the drill bit is not aligned with the center of gravity of the drilling rig, resulting in inaccurate drilling position.

Method used

By receiving path information, the drilling rig position is determined, and a first reference point associated with the drilling rig is used to instruct the drilling rig to follow the path. A second reference point is activated at the trigger position until the target position is reached and the second reference point is activated to instruct the drilling rig to stop.

Benefits of technology

It achieves precise positioning of the drill bit, ensuring drilling accuracy and efficiency, avoiding path gaps caused by reference point switching, and improving the automation and precision of drilling.

Abstract

Apparatus, method, and computer program product for: receiving information about a path to be followed by a drilling rig, the path including a trigger position; determining the position of the drilling rig; instructing the drilling rig to follow the path based on a first reference point associated with the drilling rig; activating a second reference point associated with the drilling rig in response to determining that the position of the drilling rig corresponds to the trigger position; and instructing the drilling rig to stop in response to determining that the position of the second reference point corresponds to a target position.
