Description
Technical field
This utility model belongs to underwater hose technical field, especially relates to a kind of intelligent water bottom hose.
Background technology
Underwater hose is in marine oil and gas production process, along with the gradually intensification of mining depth, and complies with the one of generation not
The product that can or lack, is now widely used for deep water hydrocarbon production process.It mainly assume responsibility for from underwater well head and waterborne flat
Platform, the transmission of the Oil, Water, Gas medium between platform and platform.
Traditional underwater hose is usually the most nested with metal material by composite, non-adhesive.The most permissible
Ensure the rigidity of pipeline, so that it can carry necessary inside and outside pressure loading, tension, anti-shearing force etc., with
Time make again pipeline possess flexibility so that it is under the effect of deep water wave stream, anti-fatigue performance is greatly improved.
But, the properly functioning of flexible pipe is faced with great challenge, 1, delivered inside medium possess corrosivity；2, in high salt
The composite bed caused under high-pressure environment and under fatigue effect is aging；3, wave during the change of environmental load, such as typhoon
The stream effect infringement to underwater hose；4, there is potential risk to flexible pipe in the operation of third party's anchorage regardless.And it is the softest
Pipe is more and more applied in deep water hydrocarbon mining system, to its detection and the disappearance of monitoring method so that it is become one
, once there is pipe damage in technology blind spot completely, it will causes the warp of serious marine environmental pollution and manufacturing enterprise
Ji loss.
Utility model content
The purpose of this utility model is to overcome prior art not enough, it is provided that a kind of intelligent water bottom hose so that it is can detect
The state of self.
The technical solution of the utility model is: a kind of intelligent water bottom hose, and including inner tube, said inner tube is hollow-core construction,
Outside said inner tube, it is coated with compound sleeve, outside described compound sleeve, is coated with metallic sheath, wrap outside described metallic sheath
It is covered with armouring wire, outside described armouring wire, is coated with oversheath, be provided with between described compound sleeve and metallic sheath
At least temperature-measuring optical fiber.
Further, in described metallic sheath, many strain detecting optical fiber and vibration detection optical fiber it are spaced.
Further, described temperature-measuring optical fiber is attached to the medial wall of metallic sheath.
Further, the tube wall material of said inner tube is C15 rustless steel.
Further, the material of described compound sleeve is polyethylene.
This utility model has the advantage that with good effect: owing to using technique scheme, can pass through real-time online
Monitoring own temperature change, there is breakage in analysis conduit itself, in real time detection pipeline strain situation, calculates whether flexible pipe is subject to
Arrive foreign impacts.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is elaborated.
Shown in structural representation as of the present utility model in Fig. 1, this utility model provides a kind of intelligent water bottom hose, including interior
Pipe 1, said inner tube 1 is hollow-core construction, is coated with compound sleeve 2 outside said inner tube 1, outside described compound sleeve 2
It is coated with metallic sheath 3, outside described metallic sheath 3, is coated with armouring wire 4, be coated with outside described armouring wire 4
Oversheath 5, is provided with at least temperature-measuring optical fiber 6 between described compound sleeve 2 and metallic sheath 3.
Many strain detecting optical fiber 7 and vibration detection optical fiber 8 it is spaced in described metallic sheath 3.Described temperature-measuring optical fiber 6
It is attached to the medial wall of metallic sheath 3.The tube wall material of said inner tube 1 is C15 rustless steel.The material of described compound sleeve 2 is
Polyethylene.
The work process of this example: the intelligent water bottom hose that this utility model provides, between compound sleeve 2 and metallic sheath 3
Being provided with at least temperature-measuring optical fiber 6, this thermometric uses optical time domain reflection distributed temperature measuring technology based on Raman scattering；As
Really interior media corrosion causes metallic sheath 3 breakage of inside, such as, occur that crude oil leaks into this layer, then this temperature measuring optical
Fine 6 can experience temperature raises, thus realizes reporting to the police, if outside oversheath 5 is damaged, sea water enters, and can lead equally
Causing variations in temperature, in a word, as long as causing temperature anomaly to change, this temperature-measuring optical fiber 6 can realize reporting to the police, location；At gold
Belong to and set 3 is implanted strain detecting optical fiber 7 and vibration detection optical fiber 8；Strain detecting optical fiber 7 and vibration detection optical fiber 8 based on
The optical time domain reflection distributed strain of Brillouin scattering and temperature monitoring and distributed vibration monitoring based on coherent rayleigh noise
Technology.In this strain detecting optical fiber 7 and vibration detection optical fiber 8 are arranged on metallic sheath 3 and be rigidity with armouring wire 4
Connecting, once flexible pipe is by external impacts, then can detect that abnormal vibrations, and report to the police, location.
Described temperature-measuring optical fiber 6 temperature-measuring range-20～120 degrees Celsius, vibration measurement scope 5kHz of vibration detection optical fiber 8 with
In, strain detecting optical fiber 7 strain measurement scope ± 5000 microstrain, positioning precision 5m, measure overall length 10km.
Intelligence flexible pipe, can measure the dynamic strain during operation in real time.Can monitor the accidents such as similar armoury wire fracture and
Can be confident of guaranteeing remanent fatigue life.Temperature survey along the line such as can be supervised as supplementing that flow assurance is assessed
Test tube road internal and outernal leakage, avoid closing down the gas hydrate synthesis of period.
Above an embodiment of the present utility model has been described in detail, but described content be only of the present utility model relatively
Good embodiment, it is impossible to be considered for limiting practical range of the present utility model.All made according to this utility model application range
Impartial change and improvement etc., within all should still belonging to patent covering scope of the present utility model.
