The invention provides a deepwater oil and gas pipeline axial guiding and centralizing ferrule type liquid flooding connecting device applied to underwater quick connection of a deepwater oil and gaspipeline. The ferrule type liquid flooding connecting device adopts an axial symmetrical type structure and a metal static sealing mode, conducts deepwater quick centralizing operation according to aslip centralizer and a centralizing liquid flooding device and conducts deepwater axial guiding ferrule type quick butt-joint connection operation through a rod type guider, a ferrule butt-joint connector and a ferrule liquid flooding device; and a pipe end joint is connected to the pipe side end of the deepwater oil and gas pipeline, the slip centralizer is clamped to a connecting pipe and the deepwater oil and gas pipeline according to power of the centralizing liquid flooding device to achieve the axial centralizing effect, the rod type guider achieves the axial guiding effect according tospline guide rails between main guiding rods and clamping claw sleeves and semi-cylindrical surface moving pairs between auxiliary guiding rods and the clamping claw sleeves, and the ferrule butt-joint connector completes underwater butt-joint connection of the rod type guider and the pipe end joint according to the power of the ferrule liquid flooding device and butt-joint clamping claws arrangedin a mouse cage mode and achieves the underwater self-locking effect through an automatic locking body.
Description
technical field [0001] The invention relates to a device for connecting deep-water oil and gas pipelines in the field of marine engineering, in particular to a liquid-driven connecting device for deep-water oil and gas pipelines that adopts axial guide centering and ferrule-type quick docking. Background technique [0002] Deepwater oil and gas pipelines are responsible for the transportation of oil and gas media such as crude oil produced from the seabed, qualified crude oil and associated gas. Once the deepwater oil and gas pipeline is damaged due to corrosion or other external force damage, it will cause marine environmental pollution, waste of oil and gas resources and production interruption; On the other hand, when the existing deepwater oil and gas pipelines have insufficient transportation capacity or new surrounding oilfields are connected, it is necessary to continue to expand the laying scale of deepwater oil and gas pipelines. Deepwater oil and gas pipeline connec...
