Abstract
The tube bank that the utility model relates to a kind of running surface fluting pipe box is prevented brushing up against equipment for inhibiting of vibration, and be that undulatory pipe box is formed by two semi-symmetric external surfaces, pipe box outer wall is vertical equidistantly offers four rectangular guiding grooves in the horizontal direction.The combination that pipe box endoporus number, diameter and chord length are restrained according to reality and size are determined, by the machine-shaping of plastics one.The running surface of pipe box and guiding gutter can disturb Development of Boundary Layer, and then suppress vortex-induced vibration.Meanwhile, pipe box is sleeved on outside tube bank, can relative displacement between confinement tube, prevents from colliding between pipe.The utility model cost is low, corrosion-resistant, and easy accessibility is reusable.
Description
Technical field
The utility model belongs to marine riser facility laying technology field, and the tube bank being specifically related to a kind of running surface fluting pipe box is prevented brushing up against equipment for inhibiting of vibration.
Background technology
At present, offshore and gas development is Deep In The Ocean, and cost of winning sharply raises.Riser systems is the core component of exploitation deep-sea oil gas, and it is the crucial tie of connecting platform and underwater well head.And deep-sea exploitation is often based on cluster well, extended reach well, horizontal well, below platform, be connected with many standpipes, and the attached umbilical often differed with diameter, hydraulic control hot, automatically controlled for water filling, injecting, companion etc.The vortex-induced vibration that the tube bank be made up of standpipe and attached umbilical can continue under ripple, stream effect, causes fatigue damage then, and easy collision friction between tube and tube, bring out inefficacy.Once standpipe or attached umbilical generation fatigue fracture, not only can cause huge economic loss, also can cause unpredicted destruction to local marine environment.
Therefore, suppress tube bank vortex-induced vibration, prevent from colliding between pipe, become the key of deep-sea oil gas exploitation.But current vortex-induced vibration suppression device is nearly all for single structure designs, there is no specially for the vortex-induced vibration suppression device of tube bank, more need not carry and play collision-proof function simultaneously.
Summary of the invention
Problem to be solved in the utility model is for the anti-deficiency brushing up against vortex-induced vibration suppression device and exist of existing ocean tube bank, provides that a kind of structure is simple, the tube bank of dependable performance, in-site installation running surface fluting pipe box is easily anti-brushes up against equipment for inhibiting of vibration.
To achieve these goals, the utility model adopts following technical scheme:
The tube bank of running surface fluting pipe box is anti-brushes up against an equipment for inhibiting of vibration, and be made up of two semi-symmetric pipe boxes, have the endoporus of nested tube bank inside pipe box, external surface is fit corrugated, and two ends are vertical equidistantly has bolt hole.Pipe box is sleeved on the tube bank that standpipe and attached umbilical form from both sides, is bolted fixing.Pipe box outer wall is vertical equidistantly offers four rectangular guiding grooves in the horizontal direction, and guiding gutter two bottom sides is rounded down, the initial segment of guiding gutter and pipe box outer wall smoothly transition.
In technique scheme, described pipe box outside wall surface channel openings end position to meet stream angle of attack θ be 45 ° ~ 80 °.
The utility model is owing to adopting above technical scheme, and it has the following advantages:
1, the running surface of the utility model pipe box and guiding gutter can disturb Development of Boundary Layer, and then suppress vortex-induced vibration; Meanwhile, pipe box is sleeved on outside tube bank, can relative displacement between confinement tube, prevents collision.
2, the utility model according to the combination of reality tube bank and size determination pipe box endoporus number, diameter and chord length, can facilitate onsite application.
3, pipe box of the present utility model is by the machine-shaping of plastics one, and cost is low, simple installation, corrosion-resistant, can provide certain buoyancy for tube bank.

Detailed description of the invention
Below in conjunction with accompanying drawing, concrete enforcement of the present utility model is further described:
As shown in Figure 1, a kind of tube bank of running surface fluting pipe box is anti-brushes up against equipment for inhibiting of vibration, is made up of two semi-symmetric pipe boxes 3.As shown in Figure 2, have the endoporus of nested tube bank inside pipe box 3, external surface is fit corrugated, and two ends are vertical equidistantly has bolt hole 5.Pipe box 3 is sleeved on the tube bank that standpipe 1 and attached umbilical 2 form from both sides, is bolted fixing.As shown in Figure 2,3, pipe box 3 outer wall is vertical equidistantly offers four rectangular guiding grooves 4 in the horizontal direction, and guiding gutter 4 two bottom sides is rounded down, and the initial segment of guiding gutter 4 and pipe box 3 outer wall smoothly transition, play the effect of drainage.
Wherein, described position, pipe box 3 outside wall surface guiding gutter 4 openend to meet stream angle of attack θ be 45 ° ~ 80 °.During actual use, can according to the combination of tube bank and size determination pipe box 3 endoporus number, diameter and chord length.
Embodiment:
According to the actual pipe bundle combinations in scene and size determination pipe box 3 endoporus number, diameter and chord length, once add molded.During installation, from both sides, pipe box 3 is sleeved on tube bank outside, is bolted fixing.After installation, this device is placed in seawater, as shown in Figure 4, seawater can flow along the running surface of pipe box 3, change the burble point in boundary layer, and part seawater can flow along guiding gutter 4, the development of interference edge interlayer, thus suppress coming off of vortex, reach the effect that vortex-induced vibration suppresses.Meanwhile, pipe box 3 is sleeved on outside tube bank, can relative displacement between confinement tube, prevents from colliding between pipe.
