Description
Technical field
The present invention relates to marine oil and gas exploitation technology field, specifically a kind of deepwater multi-loop connection terminal connected for oil gas drilling manifold.
Background technique
In hydraulic pipe line, 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 optimizing jointing is a technical problem.Particularly ocean environment very in, the technical difficulty of mud oil on ocean is more many greatly than land mud oil.For adapting to ocean specific work environments, have corresponding technical requirements to supporting oil drilling and extracting equipment, the most basic technical requirements has not allowed leakage.Many oil pipes can be used in petroleum production and transportation process, oil pipe arrangement is intricate, and generally length is longer, also have the place of many bendings, connect so the connection between oil pipe need use joint 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 joint mostly, need special tool that tubing spinning just can be completed when being interconnected between oil pipe or dismantling, operator are time-consuming, effort, simultaneously, double thread screw needs very high degree of adaptability when connecting, not only reduce working efficiency like this, add cost and also affect 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, because tool joint pin or female joint can not pressure-bearings, 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 ensure, particularly under the hyperbaric environments such as marine field, make the complex operation that tool joint pin communicates with female joint internal channel when tool joint pin is docked with female joint, closing speed is slow.Existing rapid pipe joint sealing effect is bad, easily causes fluid to leak.
The deficiencies in the prior art are: the joint of existing quick mounting can not take into account the effect of instant cutout and quick clamping, and snap fit is relatively traditional, the mode that many employings are threaded, need to use particular tool in dismounting or connection, operate pretty troublesome, operator are wasted time and energy, and pipeline joint can not be made in operation quickly, complicated structure simultaneously, constituent elements is more, its sealing is caused not to be guaranteed, and the connection terminal to be made up of tool joint pin and female joint, connect loaded down with trivial details, inconvenient operation, accurately location and locking can not be realized when female joint is connected with tool joint pin.
