System and method for surface steerable drilling

摘要

A system and method for surface steerable drilling are provided. In one example, the method includes monitoring operating parameters for drilling rig equipment and bottom hole assembly (BHA) equipment for a BHA, where the operating parameters control the drilling rig equipment and BHA equipment. The method includes receiving current inputs corresponding to performance data of the drilling rig equipment and BHA equipment during a drilling operation and determining that an amount of change between the current inputs and corresponding previously received inputs exceeds a defined threshold. The method further includes determining whether a modification to the operating parameters has occurred that would result in the amount of change exceeding the defined threshold and identifying that a problem exists in at least one of the drilling rig equipment and BHA equipment if no modification has occurred to the operating parameters. The method includes performing a defined action if a problem exists.

1. A method for dynamically predicting a drilling build rate during drilling of a borehole, comprising:
monitoring, by a surface steerable system coupled to a drilling rig, a plurality of bottom hole assembly (BHA) parameters and surrounding geological environment parameters that change the drilling build rate; receiving, by the surface steerable system, a plurality of current inputs for the bottom hole assembly (BHA) parameters and the surrounding geological environment parameters that change the drilling build rate; determining, by the surface steerable system, a current drilling build rate responsive to the plurality of the BHA parameters and the surrounding geological environment parameters that change the drilling build rate; determining, by the surface steerable system, an angle of attack of a BHA to a formation transition when passing through the formation transition from a first layer to a second layer responsive to the plurality of BHA parameters and a first material comprising the first layer and a second material comprising the second layer; predicting a future drilling build rate responsive to the plurality of BHA parameters and the surrounding geological environment parameters that change the drilling build rate and the determined angle of attack when the BHA passes through the formation transition from the first layer to the second layer; and controlling and predicting slides for the BHA using the surface steerable system responsive to the predicted future drilling build rate that is responsive to the determined angle of attack when the BHA passes through the formation transition from the first layer to the second layer.
