Appl. No.:

09/637108

Inventors:

Michael E. Wells - New Carrollton MD
Robert DeNale - Ijamsville MD
Roy A. Lindauer - Ridgley MD

Assignee:

The United States of America as represented by the Secretary of the Navy - Washington DC

International Classification:

G01M 700

US Classification:

73 1201, 73835

Abstract:

A unitary test piece which dimensionally conforms with standardized dynamic tear testing guidelines comprises a middle section and two end sections welded thereto. The middle section is made of the test-subject metallic material. The two end sections are each made of a metallic material which is compatible with the test-subject metallic material, and primarily serve the purpose of combining with the middle section at its longitudinal ends in order to together form the dimensionally suitable test piece. The length of the middle section is at least the minimum such length that will totally encompass plastic deformation of such metallic material when subjected to dynamic tear testing, this depending on the nature of such metallic material. Ferrous end sections are compatible with a ferrous middle section; non-ferrous end sections of a particular designation are compatible with a non-ferrous middle section of the same designation. The invention advantageously permits economical utilization of test-subject metallic material under circumstances in which available samples thereof are expensive, limited, inappropriately or problematically sized, inappropriately or problematically configured, and/or intended to be tested for one or more properties in addition to dynamic tear.

International Classification:

E21B 49/02
E21B 10/02
E21B 10/61

US Classification:

175 58, 175393, 175404

Abstract:

A core bit for cutting core samples in subterranean formations. The core bit has interior geometric features configured to control the quantity of drilling fluid, or flow split, flowing into a narrow annulus defined by an inside diameter of the core bit and an outside diameter of a core shoe. Reducing the flow split minimizes fluid invasion of a core being cut; thus, the core bit provides increased core quality and recoverability. The core bit is also adaptable for use with conventional core barrel assemblies and conventional coring techniques.

Baker Hughes Incorporated - Houston TX

International Classification:

E21B 10/60

US Classification:

175393, 175340, 175429, 175424

Abstract:

A nozzle for use on a rotary drill bit for forming a subterranean borehole includes a body and at least one passageway extending through the body from an inlet to an exit aperture. The passageway has a converging region and a diverging region. At least a portion of the diverging region of the fluid passageway is substantially bifurcated. A rotary drill bit for forming a borehole in a subterranean formation includes at least one such nozzle installed within a body of the bit and configured for communicating drilling fluid to a face of the body. A method of communicating fluid to a face of a drill bit includes introducing fluid into a passageway, causing the fluid to flow through a converging region, causing the drilling fluid to flow through a diverging region, and substantially bifurcating the drilling fluid at least within a portion of the diverging region.

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.

Appl. No.:

12/341525

Inventors:

Michael R. Wells - Lakewood CO, US
Tim K. Marvel - The Woodlands TX, US

Assignee:

Baker Hughes Incorporated - Houston TX

International Classification:

E21B 10/38
E21B 10/60

US Classification:

175429, 175431, 175340, 175393

Abstract:

The blades of a PDC bit have a nozzle between them preferably oriented laterally across the plane of the cutters on the blade and more preferably in a trough disposed adjacent the row of cutters. The cutting is less likely to adhere to the bit surface because the trough abruptly spaces back the bit surface and the spray being oriented radially preferably into the trough gets between the bit surface and the cutting before it can adhere to the bit surface using the fluid energy to drive the cutting into the junk slot.

US Classification:

175430, 175378, 175426, 175434

Abstract:

A downhole drill bit includes, a body, a plurality of cutters attached to the body, and at least one prefabricated splitter having a proximal portion and at least one distal portion. The proximal portion is encased within the body and the at least one distal portion extends outwardly of the body. Further the at least one distal portion is in operable communication with at least one of the plurality of cutters such that the at least one distal portion bifurcates cuttings cut by the at least one cutter.

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.
