DRILL BIT SIMULATION AND OPTIMIZATION |
摘要 |
A method of predicting behavior of a drill bit includes: generating, by a processor, a representation of at least one component of the drill bit, the representation representing a three-dimensional object as a combination of at least two two-dimensional polygons; representing a borehole formed in an earth formation during a drilling operation by generating a mathematical representation of a borehole surface defined by a plurality of nodes; simulating operation of the drill bit within the borehole with the application of one or both of axial load and a side load; determining whether the three-dimensional object is in contact with the borehole surface by determining if one of the nodes is within both of the two-dimensional polygons during the simulation; and estimating an amount of lateral motion of the drill bit during the simulation. |
