Threaded tubular connection for hydrocarbon well casing
A newly granted patent (Publication Number: US11885443B2) discloses a threaded tubular connection designed for drilling and exploiting hydrocarbon wells. The connection consists of a first tube with a male tool joint at one end and a second tube with a female tool joint at the other end, allowing them to be assembled along a longitudinal axis. The male tool joint features a male threaded portion, while the female tool joint has a female threaded portion that engages with the male threaded portion during assembly. The patent specifies precise mathematical conditions for the pitches of the load and stabbing flanks of the male and female threaded portions over consecutive turns, ensuring optimal performance and reliability.
Furthermore, the patent outlines additional features of the threaded tubular connection, such as specific tooth widths for the helices of the male and female threaded portions, the parallelism of certain flanks within tolerance limits, and the geometry of the thread roots and crests. The design also includes frustoconical elements with defined tapers, ensuring stability and efficiency during drilling operations. With requirements for the number of turns, taper angles, and radial heights of the flanks, the patented threaded tubular connection aims to enhance the overall performance and longevity of hydrocarbon well drilling equipment.
