Abstract
A method of designing a rotary drill bit includes selecting and positioning a plurality of cutting elements on a rotary drill bit. At least one substantially helically extending feature is selected and positioned to rotationally follow at least one of the plurality of cutting elements, the at least one substantially helically extending feature exhibiting a selected maximum Helical Pitch.
Claims7
A method of designing a rotary drill bit for subterranean drilling, comprising:
- selecting a plurality of cutting elements and positioning the plurality of cutting elements upon the rotary drill bit under design for drilling a borehole;
- selecting at least one substantially helically extending feature rotationally following and associated with at least one of the plurality of cutting elements, respectively;
- wherein the at least one substantially helically extending feature exhibits a selected Helical Pitch and exhibits a periphery that is larger than a cutting envelope of its associated cutting element.
