Background technology
With the exhaustion gradually of landing field petroleum resources, Devoting Major Efforts To Developing marine oil and gas resource has become inexorable trend.The marine floating type production system is the important tool of marine oil and gas development of resources, wherein marine riser is the communication bridge that connects offshore boring island and underwater well head, insulating sea water, guiding drilling tool and pipeline, circulating fluid and completion fluid, the heave movement etc. that compensates drill ship are had important function, are the requisite critical components of marine floating type production system.Yet the residing marine environment of marine riser is extremely complicated abominable, and its inside has high-pressure oil gas stream to pass through, the outside marine environment load that bears the complexity such as wind, wave, stream, ice and earthquake, especially with wave and ocean current load for very.Under the comprehensive functions such as the shearing of seawater and ocean current, impact, the marine riser both sides can form the whirlpool that alternately comes off, coming off of whirlpool makes marine riser be subject to periodically variable fluid force effect, thereby cause following current to the crossing current to vibration, the vibration of marine riser conversely again can the disturbance flow field, strengthened the generation of whirlpool and come off, the interactional phenomenon of this fluid and solid is so-called vortex-induced vibration.Vortex-induced vibration is the main inducing of marine riser generation fatigue damage., in case marine riser generation fatigue failure, will cause marine serious accident, also can cause catastrophic destruction to marine environment.
There is complex structure in existing marine riser vortex-induced vibration suppression device great majority, and manufacturing cost is high, and performance is unreliable, and weight is large, install loaded down with trivial details and the deficiency such as field conduct operation inconvenience.
Summary of the invention
Problem to be solved in the utility model is the deficiency that exists for existing ocean marine riser vortex-induced vibration suppression device, provides a kind of simple in structure, dependable performance, lightweight, cost is low, and is on-the-spot easy for installation, not perishable Novel guide formula vortex-induced vibration suppression device with damaging.
The utility model is by the following technical solutions: a kind of flow-guiding type vortex-induced vibration suppression device, and to arrange and form along marine riser axis direction tandem for a plurality of elementary cells, an elementary cell comprises: kuppe, deflector, afterbody baffle plate, gripper shoe.Kuppe and a pair of deflector, two pairs of gripper shoes and an afterbody baffle plate are that the mould of plastics Integratively processes; A pair of deflector is arranged symmetrically in the kuppe both sides, and the deflector two ends are connected with gripper shoe; Deflector and afterbody baffle plate are arranged in the middle part of kuppe, and be equal apart from the Edge Distance up and down of kuppe.
The utility model also comprises:
1, kuppe is the cylindrical structure that internal diameter equals the marine riser outer diameter D, and the thickness S of kuppe, deflector, afterbody baffle plate and gripper shoe is 0.05 ~ 0.08 times of marine riser outer diameter D;
2, deflector is combined by a circular arc camber deflector and a plane deflector, the concyclic axle of the arc surface of circular arc camber deflector and the face of cylinder of kuppe, between circular arc camber deflector inwall and kuppe outer wall is 0.05D ~ 0.2D apart from M, and the arc chord angle α of circular arc camber deflector is 30o ~ 45o; The length of plane deflector is T, and the angle theta between the extended line of plane deflector and afterbody baffle plate is 30o ~ 45o; The height H of deflector and afterbody baffle plate is 2D ~ 4D, and the length L of afterbody baffle plate is 1.5D ~ 2.5D.
The utlity model has following advantage:
1, kuppe of the present utility model and a pair of deflector, two pairs of gripper shoes and an afterbody baffle plate are an integral body, are sleeved on the external surface of marine riser, install simple;
2, material of the present utility model is plastics, by the mould of plastics Integratively, is processed, and has simplified manufacturing process, can significantly reduce costs, and not perishable and damage, also can be marine riser certain buoyancy is provided;
3, the utility model can suitably be adjusted the distance between each elementary cell according to on-site actual situations, makes inhibition reach best.

The specific embodiment
The utility model provides a kind of flow-guiding type vortex-induced vibration suppression device, for a plurality of elementary cells, along marine riser 1 axis direction tandem, arranges and forms, and an elementary cell comprises: kuppe 2, deflector 3, afterbody baffle plate 4, gripper shoe 5.As shown in Figure 1 and Figure 2, kuppe 2 and a pair of deflector 3, two pairs of gripper shoes 5 and an afterbody baffle plate 4 process for the mould of plastics Integratively; A pair of deflector 3 is arranged symmetrically in kuppe 2 both sides, and deflector 3 two ends are connected with gripper shoe 5; Deflector 3 and afterbody baffle plate 4 are arranged in the middle part of kuppe 2, and be equal apart from the Edge Distance up and down of kuppe 2.
As shown in Figure 1, during actual installation, the elementary cell tandem is sleeved on marine riser 1 external surface, and with afterbody baffle plate 4 alignment of all elementary cells, and with ocean current, flows to and parallel, and then the marine riser 1 that this device will be installed is positioned in seawater.Distance between elementary cell is generally 2D ~ 4D, also can suitably adjust according to actual conditions, makes inhibition reach best.
When ocean current was flowed through deflector 3, ocean current was with diversed plate 3 shuntings, and a part of ocean current passes through from the slit flow channel between deflector 3 and kuppe 2, through deflector 3, is drained to afterbody baffle plate 4 sidewalls, then along the parallel outflow of afterbody baffle plate 4.Phase mutual interference between the existence of afterbody baffle plate 4 has been avoided flowing from two stock markets that marine riser 1 both sides are walked around, weakened ocean current in the formation of marine riser 1 rear whirlpool of flowing through, thereby realized the inhibition of vortex-induced vibration.In addition, this device material is plastics, can be marine riser certain buoyancy is provided.
