Filed:

Dec 22, 2008

Appl. No.:

12/341398

Inventors:

Rudolf Carl Pessier - Galveston TX, US
Scott Allan Young - Montgomery TX, US
Robert J. Buske - The Woodlands TX, US
Mark Phillip Blackman - Conroe TX, US
Gregory L. Ricks - Spring TX, US

Assignee:

Baker Hughes Incorporated - Houston TX

International Classification:

E21B 10/26

US Classification:

175344, 175385, 175406

Abstract:

A reamer bit for use in earth boring operations comprising a body, four cutter mounts, rolling cutters on each mount, and cutting elements disposed on each cutter arranged so adjacent cutting swaths formed by the bit are created by cutting elements on cones of oppositely disposed cutter mounts. The swaths are generally curvilinear, wherein the outermost swaths are formed by cutting element rows on the outer portion of the cutters. The reamer bit can further comprise a pilot bit.

International Classification:

E21B 10/52
E21B 10/08
E21B 10/50

US Classification:

175341, 175374

Abstract:

An earth boring drill bit comprising cones, each cone having rows of inserts, where the inserts are in the form of a pyramid with four sides. The insert includes ridges at the juncture of each adjacent side. The ridges extend to the top of the insert and meet at a crest. Oppositely disposed ridges on the insert lie substantially in the same plane, thereby forming two planes intersecting on the crest. The two planes are substantially perpendicular. The inserts are arranged on the cone such that one plane is substantially parallel with the insert row, and the other is substantially parallel with the cone axis.

International Classification:

E21B 10/00
B21K 5/04

US Classification:

175336, 761082

Abstract:

An earth boring drill bit designed for a specific performance, within a finished product tolerance, using components built to a looser manufacturing tolerance. The bit may be assembled by selecting a leg from a plurality of pre-manufactured legs; selecting a bit body from a plurality of pre-manufactured bit bodies, the bit body having a slot for receiving the leg; placing the leg within the slot; and fixing the leg within the slot within the finished product tolerance by placing one or more shims between the leg and the slot. The shims may be used to adjust an axial position, a radial position, and/or a circumferential position of the leg with respect to the slot. The leg and the bit body may be selected, or produced, to ensure the bit will not meet the specification, given the manufacturing tolerance, without the shims.
