As a preferred embodiment of the present invention, it is communicated with several branch pipes on described sleeve pipe head, is provided with gate valve on branch pipe.
Compared with prior art, the utility model has the beneficial effects that
1, the utility model conduit, bracket, casing head are successively fixed, and conduit is fixed to after ground, fixed in casing head
Casing suspension hoop surface pipe can be supported.The top bar of casing head can engage the box cupling upper limb of surface pipe.When stubborn
When bolt between fixed tube head and suspension pallet, top bar and casing the suspension hoop of casing head get out of a predicament or an embarrassing situation and jointly cover surface layer
The box cupling clamping of pipe, thus, surface pipe is effectively hung.Since the end face of surface pipe box cupling is effectively supported, surface layer
Longitudinally opposite sliding will not be generated between box cupling and casing the suspension hoop of casing, ensure that connection is reliable, the operation of suspension compared with
It is simple.Supported and suspended formula connection between casing head and surface pipe box cupling is avoided using welded type, screw-type and slips
When formula, the problem of box cupling of surface pipe need to be removed, operation is simplified.Also, the utility model also avoids slip-type connection
When, surface pipe has that slips is skidded or damaged.
2, casing suspension hoop effectively supports surface pipe, will not between box cupling and casing the suspension hoop of surface pipe
Longitudinally opposite sliding is generated, seal assembly can guarantee its sealing effect in stable environment.Banking pin is avoided that sealing group
Part slides, and further increases the sealing effect of seal assembly.
3, slips hanger passes through the side wall of tensioning technique casing, so that protective casing obtains suspension strut.
4, gate valve, the folding of controllable each branch pipe of gate valve are provided on branch pipe.

Specific embodiment
With reference to the accompanying drawing, the utility model is described in detail.
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only to explain this
Utility model is not used to limit the utility model.
Implementation process:
Suspension surface pipe 4 and installation wearing bush: bracket 2 is welded on conduit 1, for fixing entire wellhead assembly
Steadily, but it is not subject to the weight of entire wellhead assembly.Surface pipe 4 is inserted into the utility model lower part, suspension pallet 5 is tightened
On casing head 3, since casing suspension hoop 6 and suspension pallet 5 are fixed, then casing suspension hoop 6 hangs surface pipe 4 and compresses close
Sealing assembly 7 seals surface pipe 4.After surface pipe 4 is hung in success, it should carry out greasing examination to the seal assembly 7 in casing head 3
Pressure, to check the sealing performance of the sealing ring.After pressure testing is qualified, drilling well work can continue.In drilling process, in casing head 3
It needs that wearing bush is installed, in case drilling tool damages each sealing surface in 3 inner cavity of casing head.
Sit and hang slips hanger 9: with after 9 Suspension Technique casing 8 of slips hanger, connect and fasten by bolt and nut on
3 component of parts casing pipe head forms sealing.After completing the installation of slips hanger 9, is solidified to mud, utilize the pressure testing hole of upper member
Pressure testing is carried out to casing suspension device.After pressure testing is qualified, drilling well work can continue.
Embodiment one
A kind of surface pipe suspension arrangement, including conduit 1, bracket 2 is fixedly connected on conduit 1, and the other end of bracket 2 is solid
Surely there is casing head 3, the top bar 31 of the upper limb of the box cupling 41 for engaging surface pipe 4, casing head 3 are provided in casing head 3
Lower end be bolted suspension pallet 5, hang pallet 5 on be fixed with casing suspension hoop 6, casing suspension hoop 6 in setting
There is be used to support surface pipe box cupling lower edge to get out of a predicament or an embarrassing situation 61.
The utility model conduit 1, bracket 2, casing head 3 are successively fixed, and conduit 1 is fixed to after ground, solid in casing head 3
Fixed casing suspension hoop 4 can be supported surface pipe 4.The top bar 31 of casing head 3 can engage the box cupling 41 of surface pipe 4
Upper limb.When tightening casing head 3 and hanging the bolt between pallet 5, under top bar 31 and casing the suspension hoop 6 of casing head 3
Step 61 jointly by 41 clamping of box cupling of surface pipe 4, thus, surface pipe 4 is effectively hung.Due to connecing for surface pipe 4
The end face of hoop 41 is effectively supported, and will not generate longitudinally opposite cunning between box cupling 41 and casing the suspension hoop 6 of surface pipe 4
It moves, ensure that connection is reliable, the operation of suspension is relatively simple.It is supported and suspended between casing head 3 and the box cupling 41 of surface pipe 4
The problem of formula connection when avoiding using welded type, screw-type and slip-type, need to remove surface layer and cover, 4 box cupling 41, simplifies
Operation.Also, when the utility model also avoids slip-type connection, surface pipe 4 has that slips is skidded or damaged.
