Abstract

The invention provides a marine deepwater oil gas pipeline axial push type hydraulic driving quick joint device, and is applied to underwater connection of deepwater oil and gas pipelines. The quick joint device sequentially carries out underwater axial positioning operation and underwater butt joint operation according to a butting device, an axial push base body and a hydraulic shaft pusher, theunderwater sealing connection operation is carried out through a sealer and a locking positioner, rapid butt joint and sealing of the quick joint device and an underwater pipeline are realized, the hydraulic shaft pusher provides driving force, the axial pushing base body realizes the axial positioning of the butting device according to the axial pushing and positioning mechanism and serves as asupporting point for axially pushing the butting device, the butting device is connected to the pipe end of the underwater pipeline according to the column surface slideway between an annular cavity and the underwater pipeline, and the locking positioner is used for completing the axial fixing connection of the butting device at the pipe end of the underwater pipeline according to the power provided by an oil inlet manifold and a locking and positioning mechanism and a locking and anchoring mechanism. The sealer completes the metal sealing between the underwater pipeline and the butting deviceaccording to the power supplied by the oil inlet manifold and the sealing and anchoring mechanism.

Description

technical field [0001] The invention relates to a joint device of an underwater oil and gas pipeline, in particular to a shaft-push hydraulically driven quick joint device for connecting an ocean deep water oil and gas pipeline. Background technique [0002] In the underwater production system of marine engineering, the deep water oil and gas pipeline is a very important oil and gas transportation equipment. In engineering practice such as oil field, marginal oil field and underwater pipeline maintenance. [0003] At present, in the construction of domestic underwater pipeline projects, the connectors and quick connectors used for the connection of offshore deepwater oil and gas pipelines are usually designed by foreign companies, and the software, hardware, and even construction tools are also purchased or rented from foreign companies. Representative products are UNITECH Subsea in Norway, FMC Technologies and Oceaneering in the United States, and VIPER Subsea in the Unite...
