Abstract
The utility model discloses an oil exploration land-used reinforced special communication cable in the communication cable field. The oil exploration land-used reinforced special communication cable comprises four insulation wire cores wrapped with polyester belt layers; a high-density polyethylene insulation layer is extruded outside seven strands of oxygen-free copper wires to form each insulation wire core; a polyurethane sheath is extruded on the periphery of the polyester belt layer; and the polyurethane sheath is internally provided with an aramid fiber reinforced core parallel with the insulation wire core. The oil exploration land-used reinforced special communication cable enhances stability of cable signal transmission, enhances tensile strength of the cable and wear-resistance and heat-resistance performances, and can be used in underground oil exploration.
Description
Technical field
The utility model relates to a kind of cable, particularly a kind of telecommunication cable.
Background technology
Along with society and expanding economy, people's living standard improves constantly, take a bus instead of walking and become the important component part of modern's life, the development of transportation is more and more faster simultaneously, all these vehicles are mostly to using oil as main power resource, thereby oil becomes the energy that country is main, every country all, finding by every means new oil field, ensures the high speed development of domestic economy with this.
Make a general survey of the concrete utilization of oil exploration technology in recent years, modal no more than seismic prospecting, so-called seismic prospecting is exactly by manual method earthquake-wave-exciting, the situation that Study of Seismic ripple is propagated in stratum, to find out underground geological structure, for finding a kind of geophysical prospecting method of oil gas field or other exploration object services.In China, since Daqing oil field is found, most finds all provide structure by seismic data and find.Many big-and-middle-sized oil fields such as oil field, the Gulf of Mexico in the world, oil field, the Middle East, oil field, the Caspian Sea are also like this.Can say, if there is no seismic prospecting, modern oil-gas exploration oil prospecting gas finding is just difficult to carry out.Can expect, seismic prospecting will brought into play significant role aspect searching oil gas.
The step of carrying out on land seismic prospecting is played order: measure operation-excite operation-unwrapping wire operation-blast operation-data acquisition-instrument to receive operation, so the collection that completes these data need to complete and gathers and transmit Macro or mass analysis by cable.
Utility model content
The purpose of this utility model is to provide a kind of oil exploration land Special reinforcement telecommunication cable, and its stable signal transmission is high, and tensile strength is high, has better antiwear heat resisting performance.
The purpose of this utility model is achieved in that a kind of oil exploration land Special reinforcement telecommunication cable, comprise that four outsides are surrounded with the insulated wire cores of polyester belt, seven strands of copper free wires that every insulated wire cores is extruded with high density polyethylene (HDPE) insulating barrier by outside form, described polyester belt periphery is extruded with polyurethane jacket, is provided with the aramid fiber thread reinforcement core paralleling with insulated wire cores in described polyurethane jacket.
Compared with prior art, the beneficial effects of the utility model are, the utility model selects sheath that polyurethane is made to strengthen thermal endurance, resistance to wear and the tensile strength of cable, adopts the wrapped mode of polyester belt to guarantee the roundness of insulated wire cores.The utility model can be used in underground petroleum exploration.
In order to strengthen the stability of cable signal transmission, described seven strands of copper free wires evenly twist together.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Wherein, 1 polyurethane jacket, 2 polyester belts, 3 high density polyethylene (HDPE) insulating barriers, 4 copper free wires, 5 aramid fiber thread reinforcement cores.
Embodiment
A kind of oil exploration land Special reinforcement telecommunication cable as shown in Figure 1, comprise that four outsides are surrounded with the insulated wire cores of polyester belt 2, seven strands of copper free wires 4 that every insulated wire cores is extruded with high density polyethylene (HDPE) insulating barrier 3 by outside form, seven strands of copper free wires 4 evenly twist together, polyester belt 2 peripheries are extruded with polyurethane jacket 1, are provided with the aramid fiber thread reinforcement core 5 paralleling with insulated wire cores in polyurethane jacket 1.
The utility model is by evenly twisting together seven strands of copper free wires 4 stability that has strengthened cable signal transmission, select sheath that polyurethane is made to strengthen thermal endurance, resistance to wear and the tensile strength of cable, adopt the wrapped mode of polyester belt to guarantee the roundness of insulated wire cores.
The utility model is not limited to above-described embodiment; on the basis of the disclosed technical scheme of the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some replacements and distortion to some technical characterictics wherein, these replacements and distortion are all in protection range of the present utility model.
