The intensity of waterproof casing self structure can not be made full use of, but is newly provided with an easy jacket platform, such one
Come, not only additionally increases jacket structure, increase design, construction and installation workload；Moreover, also adding steel use
Amount, economy are relatively poor.
Utility model content
The main purpose of the utility model is to overcome disadvantages mentioned above of the existing technology, and providing a kind of having support
Simple wellhead structure can not only make full use of waterproof casing structure strong after simple wellhead structure is with relying on platform to connect
Degree, solves the problems, such as that the jacket platform of nested waterproof casing need to be created, and has saved design, construction and installation workload；And
And the dosage of the materials such as steel is also saved, significantly reduce jacket platform cost of investment.
The purpose of this utility model is realized by following technical scheme：
A kind of simple wellhead structure having support, it is characterised in that：Including：It is connected with platform is relied on by connection structure
Operating platform connect the waterproof casing being linked together, the collar supports structure on waterproof casing with operating platform,
In, waterproof casing is equipped with branch block, to collar supports structure for support positioning action；Operating platform can also serve as drilling well
Platform uses.
Supporting structure is installed, supporting structure is equipped with the guiding of waterproof casing at waterproof casing mud face；Holder knot
The bottom of structure is equipped with mud mat, so that supporting structure meets intensity and stability requirement in the waterproof casing stick-up stage.
Described sleeve pipe support construction includes：Casing, the support on casing, wherein the end of support is equipped with flange.
It is described to be directed to bell mouth shape.
The beneficial effects of the utility model：The utility model due to the adoption of the above technical scheme, can not only be fully sharp
It with waterproof casing structural strength, solves the problems, such as that the jacket platform of nested waterproof casing need to be created, has saved design, built
And installation workload；Moreover, also saving the dosage of the materials such as steel, jacket platform cost of investment is significantly reduced.Its
Can be used for the case where shallow water marginal oil field or shallow water tremie frame platform increase a small amount of well head, can rely on self-elevating ocean platform,
Drill ship platform, fixed jacket platform etc..

Specific implementation mode
As Figure 1-Figure 8, the utility model includes：By connection structure 6 with rely on platform 7 be connected operating platform 1,
The waterproof casing 2 that is linked together using welding manner with operating platform 1, the collar supports structure 3 on waterproof casing 2,
Wherein, waterproof casing 2 is equipped with branch block 9, and to play support positioning action to collar supports structure 3, quantity is according to stress
Situation determines.
Supporting structure 4 is installed, supporting structure 4 is equipped with the guiding 5 of waterproof casing 2 at 2 mud face of above-mentioned waterproof casing；Branch
The bottom of frame structure 4 be equipped with mud mat 8 so that supporting structure 4 waterproof casing 2 by be oriented to 5 be inserted into sea beds after, in Free Station
When the vertical stage, meet intensity and stability requirement.
Above-mentioned collar supports structure 3 includes：Casing 10 is mounted on the support 12 on casing 10 using welding manner, wherein
The end of support 12 is set there are one flange 11.Collar supports structure 3 needs before installing the operating platform 1, is pushed up from waterproof casing 2
Decentralization is inserted in portion, decentralization to designed elevation, between support 12 by end flanges group to, be bolted, by waterproof casing 2 and casing
Support construction 3 holds together.
Above-mentioned guiding 5 is bell mouth shape.
When the utility model is used, it is connected, it can be achieved that its long-term predetermined function with platform 7 is relied on by connection structure 6.Behaviour
Make platform 1 and also serve as drilling platforms use, bears equipment component load in drilling phase, after the completion of drilling well, can also arrange oil recovery
A small amount of equipment such as tree, the operating platform 1 are connected by connection structure 6 with platform 7 is relied on, and so that the utility model is attached to support flat
On platform, to meet the predetermined function of the utility model.
Above-mentioned connection structure 6 is the prior art, and the technology not explained is the prior art, and so it will not be repeated.
