Description
Technical field
The present invention relates to marine oil and gas exploitation technology field, specifically a kind of hydraulic pressure jumper connecting for oil gas drilling manifold and test thereof, installation method.
Background technique
In hydraulic pipe line or water pipeline, usually can run into the situation that pipeline is connected.In the connection of pipeline or the process of disconnection, how to ensure the seal degree of pipeline, and the Placement of optimization jointing is a technical problem.Particularly ocean environment very in, on ocean, the technical difficulty of mud oil is more many greatly than land mud oil.For adapting to ocean specific work environments, supporting oil drilling and extracting equipment is had to corresponding technical requirements, the most basic technical requirements is not allow leakage.In petroleum production and transportation process, can use many oil pipes, oil pipe is arranged intricate, and generally length is longer, also have the place of many bendings, so need using joint, the connection between oil pipe connects to reduce tubing length and floor space, jointing must have higher sealing and compression resistance, and preferably can realize quick connection, present oil connection adopts double thread screw or flange to connect mostly, when interconnecting between oil pipe or dismantling, need special tool that tubing spinning just can be completed, operator are time-consuming, effort, simultaneously, double thread screw needs very high degree of adaptability when connecting, so not only reduced working efficiency, increase cost and also affected job schedule simultaneously.
Existing rapid pipe joint is generally used for flexible pipe joint, and it generally comprises tool joint pin and female joint, during use, tool joint pin is docked with female joint, but after generally tool joint pin is docked with female joint, could pass into fluid to pipeline.Before tool joint pin is docked with female joint, can not pressure-bearing due to tool joint pin or female joint, pipeline can not pass into fluid.In addition, existing rapid pipe joint, the internal structure more complicated of tool joint pin and female joint, in baroque situation, sealability is difficult to guarantee, particularly under the hyperbaric environments such as marine field, the complex operation that tool joint pin makes tool joint pin communicate with female joint internal channel while docking with female joint, closing speed is slow.Existing rapid pipe joint sealing effect is bad, easily causes fluid leakage.
Simultaneously, in marine oil and gas exploitation field, between two underwater installations (as production tree and manifold), conventionally by jumper, connect, traditional jumper structure is comparatively complicated, and with production tree or manifold between be connected inconvenient, be not easy to ROV operation, joint efficiency is low, and sealing can not be guaranteed.
The deficiencies in the prior art are: the joint of existing quick mounting can not be taken into account the effect of instant cutout and quick clamping, and snap fit is relatively traditional, the modes that are threaded that adopt more, in dismounting or connection, need to use particular tool, operate pretty troublesome, operator are wasted time and energy, and in operating process, can not make quickly pipeline joint, while complicated structure, constituent elements is more, causes its sealing not to be guaranteed, and existing jumper, connect loaded down with trivial details, inconvenient operation.
