Abstract

The invention provides an axially guided and centered ferrule-type liquid drive connection device for deep-water oil and gas pipelines, which is applied to the underwater quick connection of deep-water oil and gas pipelines. The ferrule-type liquid drive connection device adopts an axisymmetric structure and a metal static seal, and implements fast deep-water centering operations based on the slip centerer and centering liquid drive, and through the rod guide, ferrule butt joint and The ferrule liquid drive implements deep-water axial-guiding ferrule-type rapid docking operation; the pipe end joint is connected to the side end of the deep-water oil and gas pipeline, and the slip centering device is respectively clamped to the connecting pipe and the centering device according to the power of the centering liquid drive The axial centering effect is realized for deep-water oil and gas pipelines. The rod guide realizes the axial guiding function based on the spline guide rail between the main guide rod and the claw sleeve and the semi-cylindrical moving pair between the guiding guide rod and the claw sleeve. The sleeve docking device completes the underwater docking between the rod guide and the pipe end joint according to the power of the ferrule liquid driver and the docking claws arranged in a squirrel cage, and realizes the underwater self-locking effect through the 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...
