Abstract
The oil field hybrid optical cable of a kind of transmitting optical signal simultaneously and the signal of telecommunication.Mainly solve existing oil field downhole optic fiber and cable and need to lay respectively the deficiency that has caused increasing difficulty of construction and construction cost.It is characterized in that: described hybrid optical cable has inside and outside two-layer tubular sheath (5,1), " 8 " font strutting piece (7) that a longitudinal extension is arranged in inner sheath (5), monomode fiber bundle (9) is positioned at the gap of the inner surface formation of strutting piece (7) and inner sheath (5), the conductor of longitudinal extension (4) is evenly distributed along the outer surface of inner sheath (5), and above-mentioned parts all place oversheath (1).Have easy construction, take up room little and waterproof, insulation, characteristics such as corrosion-resistant, withstand voltage, high temperature resistant.
Description
Technical field:
The utility model relates to a kind of transmission yarn that is applied in the oil recovery field, oil field, especially relates to the hybrid cable of a kind of transmitting optical signal simultaneously and the signal of telecommunication.
Background technology:
Along with the development of modern science and technology, oil-water well Long-distance Control automation oil recovery technique has begun in the oil field extensive use.Under the special working condition in oil field, guarantee that this The Application of Technology mainly is the transmission that will guarantee two kinds of signals, a kind of is power controlling signal, another kind is a light signal.In the existing technology, transmission to these two kinds of signals, main fiber optic cable and the control signal cable of adopting transmits respectively, but in actual applications, there is following point in discovery: promptly under the situation that optical fiber and control signal cable are laid at the same time, need be lowered to two kinds of different protection tubes, doing one like this is to have increased difficulty of construction and construction cost, the 2nd, taken limited space, down-hole.
The utility model content:
Need to lay respectively the deficiency that has caused increasing difficulty of construction and construction cost in order to overcome existing oil field downhole optic fiber and cable, the utility model provides a kind of oil field hybrid optical cable, and this kind oil field hybrid optical cable has easy construction, take up room little and waterproof, insulation, characteristics such as corrosion-resistant, withstand voltage, high temperature resistant.
The technical solution of the utility model is: this kind oil field hybrid optical cable, comprise the conductor that is wrapped in the insulation sheath, be wrapped in the monomode fiber bundle in the waterproof pipe, wherein said hybrid optical cable has inside and outside two-layer tubular sheath, " 8 " font strutting piece that a longitudinal extension is arranged in inner sheath, the monomode fiber bundle is positioned at the gap of the inner surface formation of strutting piece and inner sheath, the conductor of longitudinal extension is evenly distributed along the outer surface of inner sheath, and above-mentioned parts all place oversheath.
The utlity model has following beneficial effect: because the oil field hybrid optical cable of taking such scheme is integrated into optical fiber and cable in the sheath that satisfies withstand voltage, anticorrosive and waterproof requirement, when construction, can be lowered to by a pipeline, significantly reduce construction volume.In addition, because therefore this kind cable has guaranteed that fully this opto-electrical cable is lowered to the reliability of working behind the oil-water well to have high withstand voltage, high temperature resistant, corrosion resistant stainless steel tube as overcoat.
Description of drawings:
Accompanying drawing 1 is a structure cutaway view of the present utility model.
1-oversheath among the figure, 2-polyethylene liner layer, 3-insulation sheath, 4-conductor, 5-inner sheath, 6-grease, 7-supporter, 8-waterproof pipe, 9-fiber bundle.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, this kind oil field hybrid optical cable, comprise the conductor 4 that is wrapped in the insulation sheath 3, be wrapped in the monomode fiber bundle 9 in the waterproof pipe 8, wherein said hybrid optical cable has internal layer tubular sheath 5 and outer tubular sheath 1, " 8 " font strutting piece 7 that a longitudinal extension is arranged in inner sheath 5, monomode fiber bundle 9 is positioned at the gap of the inner surface formation of strutting piece 7 and inner sheath 5, the conductor 4 of longitudinal extension is evenly distributed along the outer surface of inner sheath 5, and above-mentioned parts all place oversheath 1.
In order to guarantee to have better waterproof, can between the inner surface of strutting piece 7, light shafts 9 and inner sheath 5, fill grease 6 in the formed gap.And between the inner surface of inner sheath 5, conductor 4 and oversheath 1 extruded polyethylene inner covering in the formed gap.The material of inner sheath 5 can be polyvinyl chloride or polyethylene in this programme, and the material of oversheath 5 should be chosen as and contains the more flexible pliability of nickel composition stainless steel tube preferably.In addition, the strutting piece 7 for guaranteeing fiber strength should be chosen as the plasticity nonmetallic materials.
This cable at the bottom of the available same equipment lower going-into-well, has improved operating efficiency greatly in application, reduced job costs.
