US Patent:

7694755, Apr 13, 2010

Filed:

Oct 15, 2007

Appl. No.:

11/872069

Inventors:

Timothy King Marvel - The Woodlands TX, US
David A. Trivas - Houston TX, US
Michael R. Wells - Lakewood CO, US

Assignee:

Baker Hughes Incorporated - Houston TX

International Classification:

E21B 10/43

US Classification:

175398

Abstract:

An earth boring drill bit design for alleviating balling varies the junk slot depth in junk slots subject to balling from the other junk slots. Using variable depth bit bodies enhances the hydraulic characteristics of the bit as well as assists in the placement of the nozzles for machining purposes. This flexibility optimizes the area changes along the ducts required by the bit's operation.

E21B 7/00

US Classification:

175 57, 761084, 2940208, 175413

Abstract:

A rotary tool for drilling subterranean material is disclosed. The rotary tool includes a tool body having a distal crown end comprising a circumferential series of raised cutting blades with recessed junk slots therebetween. Cutting elements are located proximate a leading peripheral edge of the raised cutting blades and cutting control structures are located interiorly of the cutting elements at a leading surface of an adjacent junk slot. Cutting control structures are releasably secured to the tool body in the adjacent junk slot whereby a used rotary tool is refurbishable by removing worn cutting control structures without degradation to the tool body and replacing the worn cutting control structures by installing new cutting control structures in the worn cutting control structures' locations.
