Abstract

The invention discloses a hydraulic integral-type tensioning ring of a water separation tube. The hydraulic integral-type tensioning ring comprises a carrying body. An inner circle footstep is arranged at the upper end of the carrying body, the carrying body is concentrically connected with an outer casing of a well drilling splitter through a connection lockpin assembly, an outer circle of the carrying body is provided with an upper outer circle footstep and a lower outer circle footstep, a pressure-bearing ring is sleeved on the biggest periphery of the carrying body, an upper end footstep and a lower end footstep are arranged on the inner surface of the pressure-bearing ring, and a wearing ring and a rotation seal II are arranged between the pressure-bearing ring and the biggest periphery of the carrying body. A detachable pressing cover is arranged in the upper end footstep, and the pressing cover simultaneously covers on the upper outer circle footstep of the carrying body. A pressure-bearing gasket is arranged on the upper surface of the lower end footstep, a rotation seal I is installed between an inner peripheral surface of the lower end footstep and the carrying body, and a hydraulic channel is arranged inside the carrying body. The hydraulic integral-type tensioning ring is applicable to operation in deepwater and ultra-deepwater environments, and is big in carrying force, convenient and rapid to install, simple in operation, safe and reliable.

Description

Technical field [0001] The invention belongs to the technical field of offshore oil drilling equipment, and specifically relates to a hydraulic integral riser tensioning ring. Background technique [0002] When conducting offshore oil and gas drilling, a liquid transport pipeline extending from the floating drilling platform to the underwater BOP is needed-the offshore drilling riser system, which is mainly used to circulate the drilling fluid. When the riser is working, the bottom of the riser system must maintain a certain tensile force to ensure the stiffness of the riser to avoid damage to the bottom riser assembly and the flexible joints of the lower riser due to the pressure on the bottom of the riser system. Therefore, it is necessary to use a riser tensioner to provide top tensioning force to the riser system, and the riser tension ring is the key bearing equipment connecting the riser tensioner and the riser expansion device. Its structure and connection method have an ...
