SYSTEM AND METHOD FOR REMOTELY CONTROLLED SURFACE STEERABLE DRILLING

摘要

A system and method for surface steerable drilling are provided. In one example, the system receives feedback information from a drilling rig and calculates an estimated position of a drill bit in a formation based on the feedback information. The system compares the estimated position to a desired position along a planned path of a borehole. The system calculates multiple solutions if the comparison indicates that the estimated position is outside a defined margin of error relative to the desired position. Each solution defines a path from the estimated position to the planned path. The system calculates a cost of each solution and selects one of the solutions based at least partly on the cost. The system produces control information representing the selected solution and outputs the control information for the drilling rig.

1. A method for identifying potential issues while drilling comprising:
monitoring, by a surface steerable system located remotely at a location separate from a drilling rig, a plurality of operating parameters for drilling rig equipment that is part of the drilling rig and bottom hole assembly (BHA) equipment for a BHA coupled to the drilling rig and positioned in a borehole that is being drilled, wherein the operating parameters control the drilling rig equipment and BHA equipment; receiving, by the surface steerable system located remotely at the location separate from the drilling rig, a plurality of current inputs corresponding to performance data of the drilling rig equipment and BHA equipment during a drilling operation of the borehole; determining, by the surface steerable system located remotely at the location separate from the drilling rig, that an amount of change between any of the plurality of current inputs and a corresponding plurality of previously received inputs exceeds a defined threshold; determining, by the surface steerable system located remotely at the location separate from the drilling rig, whether a modification to the operating parameters has occurred that would result in the amount of change between the plurality of current inputs and the corresponding plurality of previously received inputs exceeding the defined threshold; identifying, by the surface steerable system located remotely at the location separate from the drilling rig, that a failure has potentially occurred in at least one of the drilling rig equipment and BHA equipment if no modification has occurred to the operating parameters; and performing, by the surface steerable system located remotely at the location separate from the drilling rig, a defined action if the failure has potentially occurred, wherein the defined action includes activating additional monitoring that includes performing the monitoring more frequently and performing the monitoring at a higher level of detail.
