Patent number: 11220868Abstract: 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.Type: GrantFiled: June 13, 2019Date of Patent: January 11, 2022Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Youhe Zhang, Yuri Y. Burhan, Huimin Song

Patent number: 10450803Abstract: An expandable tool includes a body and a recess extending at least partially through the body from an outer radial surface of the body. A spline insert may be at least partially positioned in the recess and coupled to the body. The spline insert may include a single spline or multiple splines. A cutter block or other expandable member may be at least partially positioned in the recess. The cutter block or other expandable member may include a spline on a side surface thereof, which spline may be engaged with the one or more splines of the spline insert. Engagement between one or more splines of the spline insert and spline of the cutter block or other expandable member may allow the expandable member to move radially outward from a retracted position to an expanded position, and vice versa.Type: GrantFiled: January 10, 2019Date of Patent: October 22, 2019Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Manoj D. Mahajan, Timothy A. Burdett, Yuri Y. Burhan, James A. Barnhouse, Vincente S. Salvo, Kenneth D. Hora

Patent number: 10350733Abstract: Methods for joining an ultra-hard body, such as a thermally stable polycrystalline diamond (TSP) body, to a substrate and mitigating the formation of high stress concentration regions between the ultra-hard body and the substrate. One method includes covering at least a portion of the ultra-hard body with an intermediate layer, placing the ultra-hard body and the intermediate layer in a mold, filling a remaining portion of mold with a substrate material including a matrix material and a binder material such that the intermediate layer is disposed between the ultra-hard body and the substrate material, and heating the mold to an infiltration temperature configured to melt the binder material and form the substrate.Type: GrantFiled: December 3, 2015Date of Patent: July 16, 2019Assignee: SMITH INTERNATIONAL, INC.Inventors: Liang Zhao, Xiaoge Gan, Yahua Bao, Yuri Y. Burhan, Youhe Zhang, J. Daniel Belnap, Zhijun Lin

Patent number: 10267096Abstract: A cutting element includes a sleeve, a rotatable cutting element, and at least one retaining ring. The sleeve has a first inner diameter and a second inner diameter, wherein the second inner diameter is larger than the first inner diameter and located at a lower axial position than the first inner diameter. The rotatable cutting element has an axis of rotation extending therethrough, a cutting face, a body extending axially downward from the cutting face, wherein the body has a shaft that is disposed within the sleeve, and a circumferential groove formed around an outer surface of the shaft. The at least one retaining ring is disposed in the circumferential groove and extends at least around the entire circumference of the shaft, wherein the at least one retaining ring protrudes from the circumferential groove, thereby retaining the rotatable cutting element within the sleeve.Type: GrantFiled: May 16, 2018Date of Patent: April 23, 2019Assignee: SMITH INTERNATIONAL, INC.Inventors: Yuri Y.
