The invention provides a stretching-resistant and pressure-resistant umbilical cable, and belongs to the technical field of umbilical cables. The stretching-resistant and pressure-resistant umbilical cable comprises a tension force bearing layer, a pressure bearing layer and internal function component which are sequentially arranged in an outer sheath. The umbilical cable has a good stretching and compression bearing capacity.
Description
Technical field
The present invention relates to the measuring body umbilical cables of a kind of tension, belong to the umbilical cables technical field.
Background technology
Umbilical cables is widely used in the Application and Development of offshore oil and natural gas, and especially the steel pipe umbilical cables, apply more and more general.The steel pipe umbilical cables is leaned on steel pipe self bearing tension usually, and generally can not bear pressure.Yet along with oil gas field develops to deep-sea, umbilical cables will be born larger pulling force, and, umbilical cables is born pressure when mounted possibly, therefore, be necessary to design and a kind ofly can improve umbilical cables stretching bearing capacity, can allow again umbilical cables bear the Novel navel cord cable of certain axial compressive force.
Summary of the invention
The stretching and the limited shortcoming of compression bearing capacity that exist for overcoming existing umbilical cables, goal of the invention of the present invention is to provide the measuring body umbilical cables of a kind of tension, and described umbilical cables has good stretching and compression bearing capacity.
For realizing described goal of the invention, the invention provides the measuring body umbilical cables of a kind of tension, it comprises that the pulling force that is successively set in oversheath bears layer, pressure bearing layer and built-in function member.
Preferably, one deck or multilayer that the pressure bearing layer consists of around the built-in function member the high-strength material of one or more strip, the intensity of described high-strength material is more than 250MPa.
Preferably, the high-strength material of the strip of pressure bearing layer around fuse around direction and the angle of the axis of umbilical cables between 60 degree are spent with 89.
Preferably, pulling force bears one or more layers that layer consists of around the pressure bearing layer many strip high-strength materials.
Preferably, the pulling force high-strength material that bears layer around the angle of the direction of pressure bearing layer and the axis of umbilical cables between 1 degree and 30 is spent.
Preferably, described high-strength material is selected from one or more of following material: steel disc, glass fiber sheets and carbon fiber sheet.
Compared with prior art; umbilical cables provided by the present invention is born layer by having increased pressure bearing layer and pulling force targetedly; effectively protected the steel pipe of umbilical cables internal structure to avoid the impact of the outside axial tensile force of umbilical cables and axial compressive force; thereby greatly improved the whole axial tensile force of umbilical cables and the ultimate bearing capacity of axial compressive force, significantly widened the range of application of umbilical cables.

Embodiment
Describe the present invention in detail below in conjunction with accompanying drawing, identical Reference numeral represents identical parts.
Fig. 1 is the cross sectional representation of the measuring body umbilical cables of tension provided by the invention.as shown in Figure 1, the invention provides the measuring body umbilical cables of tension and comprise successively from inside to outside 3 cables or optical cable 11, inner sheath 12, 6 steel pipes 13, pressure bearing layer 14, pulling force bears layer 15 and oversheath 12, wherein, 3 cables or optical cable 11, inner sheath 12 and 6 steel pipes 13 form the built-in function member, 3 cables or optical cable 11 are with the counterclockwise spiral winding of winding angle with central shaft angle 2-10 degree, between 3 cables or optical cable 11, binder free only contacts by spiral winding, frictional connection together, 6 steel pipes 13 are with the counterclockwise spiral winding inner sheath 12 of winding angle with central shaft angle 2-10 degree, between 6 steel pipes, binder free only contacts by spiral winding, frictional connection together.Steel pipe can be used as hydraulic tube, chemical agent pipe, and between pipe, packing can be filled in gap.
Fig. 2 is the three-dimensional cutaway view of the measuring body umbilical cables of tension provided by the invention.As shown in Figure 2, pressure bearing layer 14 is formed around 6 steel pipes by the high-strength material of one or more strip, around direction and the angle of the axis of umbilical cables between 60 degree are spent with 89.Pulling force bears layer 15 high-strength material by many strips and forms around the pressure bearing layer, around the angle of axis of direction and umbilical cables between 1 degree and 30 is spent.The intensity of described high-strength material is more than 250MPa.Described high-strength material is selected from one or several in following material: strip steel disc, glass fiber sheets and carbon fiber sheet.The outside that pulling force bears layer is oversheath.
Fig. 3 is that the pulling force of the measuring body umbilical cables of tension provided by the invention bears a layer schematic diagram.As shown in Figure 3, pulling force bears layer and 15 many strip high-strength materials, around the pressure bearing layer, consists of, its around direction almost become parallel angle with the axis of umbilical cables.
Fig. 4 is the pressure bearing layer schematic diagram of the measuring body umbilical cables of tension provided by the invention.As shown in Figure 4, the pressure bearing layer consists of around 6 steel pipes one or many bar state high-strength materials, its around direction and the axis of umbilical cables degree in a vertical angle almost.
The invention provides the measuring body umbilical cables of a kind of tension, on traditional umbilical cables basis, increased pressure bearing layer and pulling force and born layer.The pressure bearing layer consists of around umbilical cables one or more high strength strip steel discs or glass fiber sheets or carbon fiber sheet.Around direction and the axis of umbilical cables degree in a vertical angle almost.When umbilical cables is subject to axial compressive force, the pressure bearing layer will provide radially constraint, prevent that the steel pipe in umbilical cables from producing flexing, thereby greatly improve the ultimate bearing capacity of the axial compression of umbilical cables.Pulling force bears layer and also one or more high strength strip steel discs or glass fiber sheets or carbon fiber sheet, around umbilical cables, consists of.But around direction almost become parallel angle with the axis of umbilical cables.When umbilical cables is subject to axial tension; pulling force bears layer and is directly stretched and bear main tensile force; and the steel pipe in umbilical cables will only bear less tensile force, thereby effectively protect the steel pipe in umbilical cables, greatly improve the ultimate bearing capacity of the axial tensile force of umbilical cables.
More than being described with reference to the accompanying drawings the present invention, is only for explaining claims but those of ordinary skills should be known in specification.But protection scope of the present invention is not limited to specification.Any those skilled in the art of being familiar with are in the technical scope that the present invention discloses, and the variation that can expect easily or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claims.
