Description
Technical field
The present invention relates to subsea production system technical field, more particularly to a kind of connection for underwater well head and production tree
Device.
Background technology
With the development of marine oil field, normal platform exploitation pattern cannot be used for ocean petroleum developing, subsea production system
It is the most effective means of deep water subsea fields exploitation.
The production tree of traditional ground peace platform and the connection of wellhead assembly, be by flange or clip form, it is necessary to work
People is installed manually using instrument.And deep water subsea production system is due to its special working environment (depth of water is more than 400m), personnel
Water cannot be descended carries out installation exercise.Therefore the exploitation of deep water subsea fields needs one kind can be by hydraulic pressure or other power
Source provides power, by remote control, realizes the attachment means of underwater well head and production tree connection and sealing.
The content of the invention
It is an object of the invention to provide a kind of for underwater well head and the connector of production tree, reliability is high, simple structure,
Long service life, is adapted to deep water subsea fields exploitation needs.
In order to realize the above object the present invention is achieved by the following technical solutions：
It is a kind of to be characterized in for underwater well head and the connector of production tree, comprising：
Adpting flange, it is arranged on production tree bottom；
Hydraulic pressure base plate, it is nested with described underwater well head；
Hydraulic connecting head, it is nested with well head under water, and is connected between adpting flange and hydraulic pressure base plate, and barrel footpath
To offering some through holes；
Card tooth, it is arranged in the through hole of hydraulic connecting head；
Push card tooth, is allowed to be contacted with the connecting-type face of underwater well head, and makes underwater well head that relative axle occur with production tree
To motion.
The connector is also included：
Several hydraulic cylinders, it is vertically set on hydraulic pressure base plate；
The hydraulic clasp being connected with hydraulic cylinder extension end respectively, its medial surface extrudes the lateral surface of the card tooth.
Described card tooth lateral surface is set to inclined-plane, drives described hydraulic clasp to move downward, and described hydraulic clasp is squeezed
The described card tooth lateral surface of pressure so that described card tooth inwardly makees radial motion.
Described card tooth inner side offers some road thread form annular grooves, and its angle of thread is 90 °.
The connecting-type face of described underwater well head is set to thread form annular groove, and it is adapted with described card tooth inner side.
A sealing ring is provided between described underwater well head and production tree.
The present invention compared with prior art, with advantages below：
The utility model reliability is high, simple structure, long service life, is adapted to deep water subsea fields exploitation needs.

Specific embodiment
Below in conjunction with accompanying drawing, by describing a preferably specific embodiment in detail, the present invention is further elaborated.
As shown in figures 1-4, it is a kind of for underwater well head X01 and the connector of production tree X02, comprising：Adpting flange 110,
It is arranged on production tree X02 bottoms；Hydraulic pressure base plate 20, it is nested with described underwater well head X01；Hydraulic connecting first 80, its
Be nested with well head X01 under water, and be connected between adpting flange 110 and hydraulic pressure base plate 20, and barrel radially offer it is some
Through hole 81, first 80 bottom of hydraulic connecting is connected on hydraulic pressure base plate 20 by bolt 10, and top is connected to connection by bolt 90
On flange 110；Card tooth 50, it is arranged in the through hole 81 of hydraulic connecting head；Push card tooth 50, is allowed to the connection with underwater well head
Type face contacts, and makes underwater well head X01 and production tree X02 that relative axial movement to occur.
In a particular embodiment, connector is also included：Several hydraulic cylinders 40, it passes through bolt 30 and is vertically set on hydraulic pressure
Base plate 20；The hydraulic clasp 70 being connected with hydraulic cylinder extension end respectively, its medial surface extrudes the lateral surface of the card tooth 50.
The above-mentioned lateral surface of card tooth 50 is set to inclined-plane, and inclination angle is less than 5 °, drives described hydraulic clasp 70 to move downward, institute
The hydraulic clasp 70 stated extrudes described card tooth lateral surface so that described card tooth inwardly makees radial motion.
The above-mentioned inner side of card tooth 50 offers some road thread form annular grooves 51, and its angle of thread is 90 °, the connecting-type of underwater well head
Face is set to thread form annular groove, and it is adapted with described card tooth inner side, and a sealing ring 90 is provided between underwater well head and production tree.
In released state, by hydraulic power source and hydraulic line, hydraulic cylinder 40 is pressurizeed, its telescopic end is withdrawn, by spiral shell
Bolt 60 drives hydraulic clasp 70 to decline, and the slope driving card tooth 50 of the inner side of hydraulic clasp 70 inwardly does radially fortune during decline
Dynamic, when card tooth 70 is contacted with the top connecting-type face (thread form annular groove) of underwater well head, 90 ° of annular grooves on card tooth 50 are subject to oblique
On the one hand lower 45 ° of deboost, this deboost produces radially outer power to card tooth 50, and this power is supported by hydraulic clasp
Disappear；On the other hand this deboost produces a downward power, this power to drive hydraulic connecting first 80 to transport downwards to card tooth 50
It is dynamic, by the conduction of bolt, drive adpting flange 110 to move downward, finally cause that adpting flange 110 is produced with underwater well head X01
On the one hand raw axial lock clamp force, this power cause that adpting flange 110 is closely connected with underwater well head X01, on the other hand by oblique
The compresses seal of face 111 brings it about deformation, so as to realize metal sealing.
In sum, the present invention is a kind of for underwater well head and the connector of production tree, and reliability is high, simple structure, make
With long lifespan, it is adapted to deep water subsea fields exploitation needs.
Although present disclosure is discussed in detail by above preferred embodiment, but it should be appreciated that above-mentioned
Description is not considered as limitation of the present invention.After those skilled in the art have read the above, for of the invention
Various modifications and substitutions all will be apparent.Therefore, protection scope of the present invention should be limited to the appended claims.
