CONTROLLED BLADE FLEX FOR FIXED CUTTER DRILL BITS |
摘要 |
An example drill bit may include a drill bit body and a flexible blade positioned on the drill bit body. The drill bit further may include a cutting element coupled to and extending a distance beyond a face of the flexible blade. The cutting element may have a back rake angle and a side rake angle. At least one of the distance, back rake angle, and side rake angle may depend on a flexed position of the flexible blade. |
