THREE DIMENSIONAL MODELING OF INTERACTIONS BETWEEN DOWNHOLE DRILLING TOOLS AND ROCK CHIPS

摘要

In accordance with some embodiments of the present disclosure, a method of modeling a downhole drilling tool is disclosed. The method may include identifying a location for each of a plurality of cutlets associated with each of a plurality of cutting elements. The method may further include calculating a depth of cut for each cutlet based on the location of the cutlet and a three dimensional model of a borehole bottom. Additionally, the method may include generating a three dimensional model of a rock chip for each cutting element, in response to at least one depth of cut being greater than a critical depth of cut, each three dimensional model including a two dimensional model of a rock chip associated with each cutlet. The method may also include updating the three dimensional model of the borehole bottom by removing each three dimensional model of a rock chip.
