The every other embodiment obtained is put, should all belong to the scope of protection of the invention.
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.
The invention provides a kind of drilling at the sea riser upper attachment means, including the fore-stock being obliquely installed and set vertically
The after-poppet put, the both sides of the fore-stock are respectively fixedly connected by a side stand 1 with the after-poppet respectively；Propped up after described
The upper end of frame is provided with female container joint unit 2；Coiled tubing supporting construction 3 is installed on the after-poppet；The fore-stock
The side of the remote after-poppet underwater connector interface unit 4 and suspension platform 5 from top to bottom are installed.
In the above-mentioned technical solutions, fore-stock and after-poppet connect and form a trapezium structure layout, have abandoned existing
The layout of rectangular frame structure in technology, and pass through finite element analysis simulating, verifying, various working conditions can be met comprehensively
Under the design requirement such as intensity, fatigue, therefore, can not only mitigate integrally-built weight significantly, and due to the letter of structure
Change, production and transport installation and the maintenance in later stage etc. is all greatly simplified, therefore significantly save manufacture and installation and transportation
Cost.For traditional box-structure, the present invention has low, intensity fatigue life height of lightweight, manufacturing cost etc. aobvious
Write advantage.
The present invention is laid out the structural framing for changing symmetric form of the prior art by above-mentioned trapezium structure, takes into full account
The serious asymmetry of load in standpipe connection, can make the direction of structure and load basically identical, give full play to structure
Potentiality.
Present invention could apply in the connection of the various standpipes of deepwater oilfield, being not limited only to SLHR, (single line is combined
Standpipe) standpipe, to production riser, service standpipe, water filling standpipe, gas transmission standpipe etc. are also suitable.Total is divided into by function
Several minor structures, production and detection after installing and installing are relatively succinct.
Preferably, the after-poppet includes two main stay tubes 6 be arrangeding in parallel, the upper end of described two main stay tubes 6
Suspension stake 7 is installed, the lower end of described two main stay tubes 6 is connected by chamfering link interface unit 8.Preferably, before described
Support includes two oblique branch pipes 11 be arrangeding in parallel.
Preferably, the upper end of the main stay tube 6 is provided with main lifting backing plate 9, the main lifting backing plate 9 and is formed with master
