Multi-parameter bit response model

摘要

A method of generating a directional response of a drill bit based on one or more drilling parameters includes performing actual or simulated tests with a drill bit in a test material having a strength under different experimental drilling parameters and recording the results of the plurality of tests. A representation of an expected directional response of the drill bit is formed based on the results. Current drilling parameters are receiving current drilling parameters at a computing device and the directional response is generated based on the current drilling parameters by utilizing the representation.

1. A computer-implemented method of generating a directional response of a drill bit based on one or more drilling parameters, the method comprising:
performing a plurality of tests with a drill bit in a test material having a strength under different experimental drilling parameters; recording the results of the plurality of tests; forming a representation of an expected directional response of the drill bit based on the results; receiving current drilling parameters at a computing device; and generating the directional response based on the current drilling parameters by utilizing the representation; wherein the representation is a matrix or a look-up table; wherein if one of the current drilling parameter is between two of the experimental drilling parameters, directional response is generated based on an interpolation between responses of the two experimental drilling parameters.
