Patent number: 11021911Abstract: A rotary guiding device includes a rotating shaft to rotationally drive a tool head. The rotating shaft includes upper and lower shaft portions, and a steerable portion, the upper shaft portion and the lower shaft portion are steerably connected by the steerable portion. A non-rotating body is mounted on the upper shaft portion, the non-rotating body is substantially non-rotating with respect to the rotating shaft in circumferential direction when the rotating shaft rotationally drives the tool head. The lower shaft portion includes a rib portion coinciding at least partially in axial direction with the non-rotating body. The non-rotating body includes at least three hydraulic driving mechanisms uniformly distributed along its circumferential direction, the three hydraulic driving mechanisms controllably generate radial drive forces respectively, the radial driving forces act on the rib portion overlapping the non-rotating body so the lower shaft portion can be deflectable relative to the steerable portion.Type: GrantFiled: March 2, 2018Date of Patent: June 1, 2021Assignee: INSTITUTE OF GEOLOGY AND GEOPHYSICS, CHINESE ACADEMY OF SCIENCESInventors: Qingbo Liu, Qingyun Di, Tsili Wang, Wenxuan Chen, Jiansheng Du, Yongyou Yang, Xinzhen He, Linfeng Hong, Qijun Xie

Patent number: 10969040Abstract: A method of connecting a first threaded tubular to a second threaded tubular includes engaging the threads of the tubulars and rotating the first tubular relative to the second tubular to makeup a threaded connection. The method further includes, during makeup of the threaded connection: measuring time, measuring torque applied to the connection, and measuring turns of the first tubular. The method further includes using a programmable logic controller for: evaluating at least one of the measured turns, measured torque, and measured time for at least one of a discontinuity, a torque spike, and a torque drop and accepting or rejecting the connection based on the evaluation.Type: GrantFiled: June 24, 2019Date of Patent: April 6, 2021Assignee: WEATHERFORD TECHNOLOGY HOLDINGS, LLCInventors: Rainer Ruehmann, Benjamin Sachtleben, David Geissler

Patent number: 10955264Abstract: A new method of gathering data real time during production or simulation tests using a gravity deployed tool, referred to as a fiber-line intervention tool (“FLI” or “FLIT”) to monitor bottom-hole pressure and temperature for well testing including the testing of adjacent wells is provided. In an embodiment, the tool is configured to include a housing, spooled fiber-line, sensors such as pressure and temperature sensors, and connections between the fiber-line and sensors such that measurement information from the sensors can be sent to the surface in real time over the fiber-line. As the housing is deployed into a well, the fiber-line can unwind, thereby providing a communication pathway from below the surface to above the surface. In an embodiment the housing can be deployed through a wellhead and down the wellbore. In an embodiment, the housing can be made of a soluble material.Type: GrantFiled: January 24, 2018Date of Patent: March 23, 2021Assignee: Saudi Arabian Oil CompanyInventors: Jonathan W. Brown, Kirk Bartko, Brett Bouldin

Patent number: 10851776Abstract: A sliding member has a sliding surface sliding under a wet condition in which a lubricant oil exists. The sliding surface is coated with a laminate film comprising an upper layer and a lower layer. The lower layer comprises hydrogen-free amorphous carbon (hydrogen-free DLC) and carbon particles dispersed on or in the hydrogen-free DLC. The hydrogen-free DLC has a hydrogen content of 5 atom % or less when the lower layer as a whole is 100 atom %. The upper layer comprises boron-containing amorphous carbon (B-DLC) and has protrusions on a surface side of the upper layer along the carbon particles of the lower layer. The B-DLC has a boron content of 1-40 atom % when the upper layer as a whole is 100 atom %. The protrusions have a particle diameter of 0.5-5 ?m and exist with a density of 20 protrusions/100 ?m2 or more.Type: GrantFiled: January 3, 2019Date of Patent: December 1, 2020Assignees: KABUSHIKI KAISHA TOYOTA CHUO KENKYUSHO, JTEKT CORPORATIONInventors: Masaru Okuyama, Hiroyuki Mori, Mamoru Tohyama, Noriyuki Emoto, Naohito Yoshida
