To be mutually combined.The utility model is described in detail with reference to embodiment.
In order that those skilled in the art more fully understand the utility model, the utility model will be implemented below
Technical scheme in example is clearly and completely described, it is clear that described embodiment is only the utility model part
Embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not doing
Go out under the premise of creative work the every other embodiment obtained, should all belong to the scope of the utility model protection.
The utility model provides connecting connection parts under a kind of deep sea vertical pipe, including be from top to bottom sequentially connected standpipe 1,
2, two main stay tubes 3 of chamfering forging link unit, connecting seat 4, flexible linker casting interface unit 5, supervisor 6 and lower flexible
Linker 7, described two main stay tubes 3 are abreast set, and the first side of the chamfering forging link unit 2 is provided with remote control machine
Tool people's mounting interface unit 8, the second side of chamfering forging link unit 2 are provided with box-shaped structural member 9, the chamfering forging
The first end of the lower end of link unit 2 and the inner tube 10 of U-shaped connects, the second end of said inner tube 10 and the box-shaped structural member 9
Remote chamfering forging link unit 2 one end connection, the second end of said inner tube 10 is provided with underwater connector interface
Unit 11.
Connecting connection parts use integrated configuration completely under deep sea vertical pipe in the utility model, have abandoned in the prior art
Traditional rectangular frame topology layout, and using the simulation result of finite element analysis to rely on, meet various working conditions comprehensively
Under the design requirement such as intensity, fatigue, can not only mitigate integrally-built weight significantly, and lower processing transport peace significantly
Dress up this.
By adopting the above-described technical solution, integrated configuration structure of the present utility model is more than structure of the prior art
Simply, therefore overall weight can be greatly reduced.If it is considered that the operating condition design of Adjacent Sea, under integrated deep sea vertical pipe
Connecting connection parts weight is between 30 tons to 70 tons.In addition, design of the present utility model has taken into full account all design works
Condition, design the serial international standard design in strict accordance with Offshore Engineering.According to international standard DNV-OS-F201, under high temperature
The yield strength of steel has certain degeneration, therefore, the utility model has had contemplated that this factor.
Although the utility model of integration is simple in construction, there is enough rigidity, the deformation under design load
May remain within safe range, the maximum distortion obtained through FEM calculation completely within safe range, relative to
For box-structure of the prior art, there is the remarkable advantages such as in light weight, manufacturing cost is low, intensity fatigue life height.This reality
It is completely different and box-structure of the prior art with new structure, due to the particularity of ocean engineering, for different
Marine site, it is necessary to which structural parameters are done with partial adjustment, therefore and uncertain specific all structural parameters.
Preferably, connecting connection parts also include standpipe standard shaft mounting interface unit 12 under the deep sea vertical pipe, installed in institute
At the upper surface for stating box-shaped structural member 9.
Preferably, connecting connection parts also include underwater connector supporting construction 13 under the deep sea vertical pipe, described to connect under water
Device interface unit 11 is connect to be connected with the second end of said inner tube 10 by the underwater connector supporting construction 13.
Preferably, connecting connection parts also include corrosion protection 14 under the deep sea vertical pipe, each main stay tube 3
On be respectively connected with least one corrosion protection 14.
Preferably, connecting connection parts also include supervisor's extension tube 15 under the deep sea vertical pipe, and the supervisor 6 passes through the master
Pipe extension tube 15 is connected with the lower flexible linker 7.
Preferably, it is provided with coating 16 on the outer wall of the supervisor 6 and supervisor's extension tube 15.
Preferably, the both sides of the chamfering forging link unit 2 are also separately installed with interface support tube 17.
Too many structure is assembled under deep sea vertical pipe among connecting connection parts by prior art, therefore causes whole deep-sea
The structure of connecting connection parts is almost complicated as connecting connection parts structure on deep sea vertical pipe under standpipe.By comparison, this practicality
The new standpipe that only retains is connected with connecting connection parts under deep sea vertical pipe, reduces the main work(of connecting connection parts under deep sea vertical pipe
Can, and in other function differentiations to surrounding structure.So, the structure of connecting connection parts under deep sea vertical pipe can be made to obtain significantly
Simplify.Although surrounding structure accordingly can structure more of the prior art it is slightly complicated, comprehensive advantage is that each subsystem is each
Its duty is taken charge of, is easy to design and installation, especially protrudes the partial function under the deep sea vertical pipe of most critical in connecting connection parts, fully
It ensure that the reliability of whole system.
Pass through above-mentioned technical proposal, connecting connection parts are relative to existing under the integrated deep sea vertical pipe in the utility model
For technology, structure greatly simplifies, but the burden for being required to fully meet loads in plane and face external applied load of bulk strength.Together
When, take into full account that caused thermal force is superimposed caused influence with production status loads in plane under production status.In addition, design
Crude oil temperature is the phase by a certain Experimental Area (for example, BP Angola Block 31) in 118 degree of standpipes of middle consideration
The operating temperature of crude oil determines under adjacent sea domain, and design have passed through the calculating of the various load of detailed finite element, result of calculation
It has been shown that, fully meets design requirement.
Deep-sea oil production technique is the weakness of China, and China is used as an energy demand big country, following marine stone
Oil exploitation has huge demand and prospect.Compared with prior art, the utility model has the advantages that structure significantly simplifies, and
More rationally, intensity fatigue life significantly improves, and cost can be greatly reduced in the manufacture and installation.
Preferred embodiment of the present utility model is the foregoing is only, is not limited to the utility model, for this
For the technical staff in field, the utility model can have various modifications and variations.It is all in the spirit and principles of the utility model
Within, any modification, equivalent substitution and improvements made etc., it should be included within the scope of protection of the utility model.
