A method for designing a drilling tool or drilling assembly and a drilling tool or drilling assembly made according to the method is provided by simulating, in an earth formation, a rock mechanics effect of the drilling tool or the drilling assembly drilling in the earth formation, graphically displaying to a design engineer the rock mechanics effect of the drilling tool or the drilling assembly drilling in the earth formation, adjusting a value of a design parameter for the drilling tool or drilling assembly, and repeating the simulating and graphically displaying to the design engineer for observing any change in the rock mechanics effect caused by adjusting the value of the design parameter.
L~invention concerne un procédé de conception d~un outil de forage ou d~un ensemble de forage et un outil de forage ou un ensemble de forage fabriqué selon le procédé. Le procédé selon l~invention comprend la simulation, dans une formation géologique, d~un effet de l~outil de forage ou de l~ensemble de forage réalisant un forage dans la formation géologique en termes de mécanique des roches, l~affichage graphique à l~intention d~un ingénieur-concepteur de l~effet de l~outil de forage ou de l~ensemble de forage réalisant le forage dans la formation géologique en termes de mécanique des roches, la modification d~une valeur d~un paramètre de conception de l~outil de forage ou de l~ensemble de forage, et la répétition de la simulation et de l~affichage graphique à l~intention de l~ingénieur-concepteur en vue d~identifier une variation éventuelle de l~effet en termes de mécanique des roches, due à la modification de la valeur du paramètre de conception.
