Patent number: 11879296Abstract: The force modulation system for a drill bit includes a cutter, a blade cap, a cap retention device, and a first force member. The cutter or cutters fit in the blade cap, and the blade cap fits to the drill bit. The cap retention device exerts a cap retention force in a first direction. The first force member exerts a first force in a second direction. The cutting profile of the force modulation system is now variable in more than one direction so as to avoid excessive forces from more than one direction for each cutter on the blade cap. There can also be a second force member to exert a second force in the first direction for more variability of the cutting profile in the first direction and a third force member to exert a third force in an opposite second direction.Type: GrantFiled: September 25, 2022Date of Patent: January 23, 2024Assignees: CNPC USA Corporation, Beijing Huamei, Inc.

Patent number: 11401749Abstract: A cutting element comprises a cylindrical substrate, a table bonded to the substrate, a working surface on the top of the table, and a plurality of dimples on the working surface. The table is made of super-abrasive material. The super-abrasive material can be PCD. Surface patterns of the table can reduce contact friction between the rock and the cutting element. Therefore, heat on the table can be reduced and thermal damage to the table is decreased. This results in improved cutting element service life.Type: GrantFiled: June 30, 2020Date of Patent: August 2, 2022Assignees: CNPC USA CORPORATION, Beijing Huamei Inc.Inventors: Chris Cheng, Jiaqing Yu, Jianhua Guo, Jie Li, Xihui Hu, Yonghong Wang

Patent number: 11365589Abstract: A cutting element comprising a cylindrical substrate; a table bonded to the cylindrical substrate; at least one tooth with a reduced projected cutting area on a periphery of the table; and a plurality of undulating cutting ridges on a top of the table. The table can have a working surface and at least one lateral surface, and a chamfer formed therebetween. The working surface can be a non-planar working surface. For a given weight on the bit, the cutter will sink into the rock deeper which can lead to better stability and more effective rock removal.Type: GrantFiled: July 1, 2020Date of Patent: June 21, 2022Assignees: CNPC USA CORPORATION, BEIJING HUAMEI, INC., CHINA NATIONAL PETROLEUM CORPORATIONInventors: Chris Cheng, Jiaqing Yu, Xu Wang, Xiongwen Yang, Yu Liu

Patent number: 10975628Abstract: A drill bit nozzle includes a nozzle body, a channel in the nozzle body, and a nozzle outlet arranged at an end of the nozzle body and in communication with the channel. The nozzle outlet is a strip-shaped outlet configured to eject a sheet-like jet flow. Since the nozzle outlet of the drill bit nozzle is a strip-shaped outlet, the nozzle outlet is able to eject a sheet-like jet flow. When the drill bit nozzle is applied to a PDC drill bit, the drill bit nozzle can uniformly eject a drilling fluid onto each cutting tooth, which ensures that the cutting teeth in the drill bit may obtain good cooling and chip removal effects, while avoiding excessive concentration of the jet flow from the drill bit nozzle which may erode the cutting teeth, thereby prolonging the service life of the drill bit.Type: GrantFiled: October 10, 2018Date of Patent: April 13, 2021Assignee: SEED TECHNOLOGIES CORP., LTD.Inventors: Yuehua Xu, Jiaqing Yu, Weixiong Wang, Jianghe Luo, Runan Zhang
