Description
Technical field
The present invention relates to one and transfer instrument for marine oil and gas production of water well head in sea, for underwater well head
Head is transferred and is installed.
Background technology
Owing to marine oil and gas exploitation has become as the important development direction of energy development, subsea wellheads head system
The various sleeve pipe in support seabed, its underpart, top carrying preventer and production tree, for the basis of submerged production.Sea
Ocean oil-gas mining investment is mostly used in the installation of undersea device, transfers instrument and letter the most simply and easily
Just installation procedure, reduces installation cost, is that marine oil and gas exploits the target always pursued.Existing marine oil
The oral instrument of transferring of gas recovery well exists not enough: 1, tool construction is complicated, and parts are many, handling procedure
Complicated time-consuming；2, reliability is low, it is impossible to locks on request or discharges well head head；3, well head head decentralization process
Always there are collision and friction.
Summary of the invention
The technical problem to be solved is to provide a kind of underwater wellhead and transfers instrument, and it can not only be right
Well head head is effectively transferred and is installed, and simple in construction handling procedure is easy, can realize well head head
Fast Installation and recovery, improve work efficiency.
This technical scheme used to solve problem set forth above is: a kind of well head head transfers instrument,
It is characterized in that including mandrel, in the middle part of mandrel, have screw thread to be connected with drive block, in upper bracer and lower support
In axial space between block；There is axially extending bore described drive block periphery, plays guide effect through bolt,
Drive block lower half directly contacts with opening elastic lock ring；Described opening elastic lock ring bottom is sat to be placed on down and is propped up
On bracer, what there were occlusion teeth groove and a well head head in outside transfers tooth engaged groove face phase configuration；Described upper bracer
It is bolted with lower bracer and plays positioning action.
By such scheme, described inner annular mandrel, it is characterised in that mandrel is a multidiameter, in centre
Screw thread is had to be connected with drive block at the axle of rank.
By such scheme, described upper bracer annular entity has through hole, curtain plate has multiple screw thread
Hole.
By such scheme, lower described bracer is opened survey and is had annular seal groove, and annular physically has screw thread
Through hole.
By such scheme, it is that drive block lower bevel is wrapped up by an inclined-plane inside described opening elastic lock ring upper end.
By such scheme, described protective cover, lower end is flare openings, and upper transverse plane has annular spread
Through hole.
The beneficial effects of the present invention is: 1, the instrument of transferring has exterior protection cover, prevent well head head decentralization process
Collision and friction, and play guide effect；2, using threaded, live spindle makes drive block move down peace
Complete reliable；3, the locking with well head head is realized by opening elastic lock ring, simple and convenient；4, install, release
Put well head head simple to operate, it is possible to achieve be quickly installed and released, save the set-up time, improve efficiency.
Accompanying drawing explanation
Fig. 1 is a schematic diagram of the present invention.
Fig. 2 be the present invention do not lock well head head schematic diagram.
Fig. 3 is the locking well head head schematic diagram of the present invention.
Fig. 4 is the elastic locking ring schematic diagram of the present invention.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the invention will be further described.
Refering to Fig. 2, well head head of the present invention transfers instrument, including mandrel 1, stay bolt 2, lag bolt 3, prevents
Guard shield 4, above prop up bracer 5, drive block 6, opening elastic locking ring 7 and lower bracer 8.
It is a multidiameter that well head head transfers tool mandrel 1, has screw thread to be connected with drive block at scala media axle.
The multidiameter two ends self-assembling formation baffle plate at screw thread place positions the position of a bracer 5 and lower bracer 8.
Having tapered thread in mandrel about 1 two stomidium, threaded upper ends is used for jointed rod or other sleeve pipes, lower end spiral shell
Stricture of vagina is used for connecting other washover tool.Drive block 6 is threadedly attached in mandrel 1.Drive block 6 annular
Physically there is an axially extending bore, the axially extending bore in drive block 6 and upper bracer 5 axially extending bore and lower bracer
Screwed hole on 8 coordinates, with stay bolt 2 phase configuration.Upper bracer 5 is sat and is placed on the boss of mandrel 1,
Annular physically has for the through hole through stay bolt 2, outer rim has screwed hole, is used for installing protective cover 4.
Upper bracer 5 annular physically has screwed hole, is pressed in mandrel 1 by stay bolt 2；Under prop up outside bracer 8
Annular seal groove is had on footpath.Opening elastic locking ring 7 is one the annulus of opening at, and outside is tooth
Shape locking slot and the locking slot phase configuration on well head head 10.There is screw thread stay bolt 2 only lower end, is used for connecting
Lower supporting plate, middle part post portion is that drive block 6 play the guiding role.
The installation of the present invention with release process is: dress is transferred the instrument taper spiral shell by mandrel 1 top
Stricture of vagina is connected on drilling rod, transfers in well head head, and rotating inner part toroidal mandrel 1 is allowed to occur with drive block 6
Relative motion, because the guide effect of stay bolt 2, drive block 6 can only descending be clamp-oned in elastic locking ring 7,
Causing elastic locking ring 7 distending to be locked in the locking slot in well head head, such well head head is just locked at whole
On instrument.Transferring to inside the conductor housing in seabed by well head head, after arriving installation site, reversion drilling rod makes the heart
Axle 1 reversion causes drive block 6 up, and elastic lock ring 7 is retracted, and whole instrument separates with well head head, whole
Installation process completes, and will carry back platform on instrument.
