Filed:

Jan 18, 2021

Appl. No.:

17/151306

Inventors:

- Sugar Land TX, US
Mingdong Cai - Cypress TX, US
Sudarsanam Chellappa - Houston TX, US
Huimin Song - Spring TX, US
Ting Ren - Conroe TX, US

International Classification:

E21B 10/46
B22D 23/06
B22D 19/06
B33Y 80/00

Abstract:

The disclosed drill tools have metal matrix composite (MMC) or steel alloy bodies that are formed around one or more pre-fabricated components using either a casting or infiltration process. The pre-fabricated components are made of sintered, infiltrated, and/or cemented particles of an ultrahard material, and may form any suitable portion of the bit blades. The pre-fabricated components may be loaded into a machined mold, and the mold cavity is subsequently filled with powder, such as tungsten carbide powder, filler metal powder, binder metal powder, or combinations thereof. During a casting or infiltration process, the mold and pre-fabricated components are heated to a sufficient temperature to melt the binder metal and/or filler metal, wherein the molten metal superficially interacts with the inner surfaces of the pre-fabricated components to form a metallurgical bond to secure the pre-fabricated components to the bit body.

International Classification:

E21B 10/43
E21B 10/633

Abstract:

A downhole tool includes a blade coupled to a body. The body and blade rotate about a longitudinal axis. A pre-formed faceplate is connected to the blade and partially defines a cutter pocket therein. Another portion of the cutter pocket is defined by the blade. The cutter pocket includes a sidewall and a base, with the sidewall formed by the blade and the pre-formed faceplate, and the base formed by the blade. The pre-formed faceplate includes a pre-formed hardfacing element. A downhole tool includes a blade coupled to a body. The body and blade rotate about a longitudinal axis. A pre-formed segment is connected to the blade and has a cutter pocket therein. The cutter pocket includes a sidewall and a base, and a cutting element is coupled to the pre-formed segment and within the cutter pocket. The pre-formed segment is optionally made of a different material than the blade and has increased wear and/or erosion resistance compared to the blade.

Huimin Song - Spring TX, US

International Classification:

E21B 10/43
F16L 15/00

Abstract:

An accessory is coupled to a body using a connection member inserted into a plurality of lateral recesses of a bore. The accessory includes a complementary connection mechanism to the connection member and is tightened in the bore with a torque. An example accessory is a nozzle for use with a drill bit. The nozzle includes threads and the drill bit includes a nozzle bore with lateral recesses. Partial thread segments are inserted into the lateral recesses, and the nozzle is threaded to the partial thread segments.

International Classification:

E21B 10/60
E21B 10/43
E21B 10/50

Abstract:

A downhole cutting tool has a body that includes a cutting end, a connection end, a longitudinal axis extending axially through the body, and a gradient composition having one or more gradients. Each gradient extends a distance in a respective direction through the body. Each gradient has changing amounts of a first material in the gradient composition along the respective direction in which the gradient extends.

International Classification:

E21B 10/567
E21B 10/573

Abstract:

A cutting element may include a substrate, an upper surface of the substrate including a crest, the crest transitioning into a depressed region, and an ultrahard layer on the upper surface, thereby forming a non-planar interface between the ultrahard layer and the substrate. A top surface of the ultrahard layer includes a cutting crest extending along at least a portion of a diameter of the cutting element, the top surface having a portion extending laterally away from the cutting crest having a lesser height than a peak of the cutting crest.

International Classification:

E21B 10/567

Abstract:

A cutting element includes a body, a non-planar cutting face formed on a first end of the body, and an edge formed around a perimeter of the cutting face. The cutting face includes a central raised portion, and the edge has an edge angle defined between the cutting face and a side surface of the body. The edge angle varies around the perimeter of the cutting face and includes an acute edge angle defined by a portion of the cutting face extending downwardly from the edge to a depth from the cutting angle. The portion of the edge defining the acute edge angle may be directly adjacent: a side surface of the cutting element; a bevel of the cutting element; or a flat region at the perimeter of the cutting element or bevel.
