Abstract
The utility model discloses a detection cable with tensile and anti-interference performance for land petroleum exploration. The detection cable comprises four copper conductor cores which are coated by polyolefin layers as insulation layers. An aramid fiber reinforcing core is in a gap at a central part of the four copper conductor cores. A shielding layer which is formed by weaving a plurality of strands of tinned copper wires coats outer surfaces of the four copper conductor cores. An outer sheath layer coats an outer surface of the shielding layer. Four polyolefin filled rope are uniformly distributed between outer sides of the four copper conductor cores and the shielding layer. The detection cable for the land petroleum exploration has the advantages of strong anti-interference ability, wide frequency band, low attenuation, adaptation to various harsh outdoor environmental conditions, stable performance, great improvement of cable tensile performance, light weight, portability and repeated use.
Description
Technical field
The utility model relates to visiting uses the exploration cable field, is specifically related to a kind of have stretch-proof, anti-interference land oil exploration exploration cable.
Background technology
Seismic prospecting is present the most frequently used oil, one of exploitation method of the mineral resources such as coal, its basic principle is to utilize artificial earthquake to produce vibration signal in the stratum or in the seawater, receive vibration signal according to designing requirement at the different location arrangements pressure vibration transducer (being geophone) of distance shot point, then the mechanical oscillation signal that receives is converted into electric signal, by the seismic survey cable electric signal is sent into seismic detector again, by seismic detector electric signal is amplified again, change binary data into through A/D converter, again data analysis is processed, frequency according to signal, amplitude, the attribute on the information analysis different depth stratum such as speed, with structural configuration etc., thereby tentatively judge whether to have oil, the conditions such as colliery provide the well location of probing at last.
Physical prospecting company advanced in the world has two at present, and the one, the ION geophysics group company of the U.S. is detection company the biggest in the world at present, its business spreads all over all over the world; Another family is French Sai Sheer Sercel company.This seismic detector of two occupies the physical prospecting market of the whole world more than 90%.Domestic physical prospecting company mainly is the east geophysics company that is positioned at the Zhuozhou, Hebei, and the seismic equipment of its outfit almost is external import entirely.And the used cable of transfer of data can not satisfy its demand far away, since geological exploration all and adverse circumstances under carry out, the damage of cable is changed inevitable, depend merely on import and do not satisfy requirement far away, and the producer of present domestic formation large-scale production does not also have.
Summary of the invention
The utility model purpose provides a kind of have stretch-proof, anti-interference land oil exploration exploration cable, this oil exploration can guarantee that with exploration cable antijamming capability is strong, bandwidth, decay little, adapt to various harsh outdoor environmental conditions stable performances, and the cable tensile property has obtained improving greatly, and is lightweight, is fit to be easy to carry and reuse.
For achieving the above object, the technical solution adopted in the utility model is: a kind of have stretch-proof, an anti-interference land oil exploration exploration cable, comprise 4 copper conductor cores, this copper conductor core outer surface is coated with the polyolefin layer as insulating barrier, one aramid fiber strengthening core is positioned at the gap of four described copper conductor core centers, the screen that is formed by some bursts of tinned copper wire braidings is coated on described 4 copper conductor core outer surfaces, and an external sheath layer is coated on described screen outer surface.
It is as follows that technique scheme is further improved technical scheme:
1. in the such scheme, four polyolefin gasket for packings are uniformly distributed between 4 described copper conductor core outsides and the screen.
2. in the such scheme, described polyolefin gasket for packing is by some stranded the forming of aramid yarn.
3. in the such scheme, described aramid fiber strengthening core is by some stranded the forming of aramid yarn.
Because technique scheme is used, the utility model compared with prior art has following advantages and effect:
The utlity model has stretch-proof, anti-interference land oil exploration exploration cable, it can guarantee that antijamming capability is strong, bandwidth, decay little, adapt to various harsh outdoor environmental conditions stable performances, and the cable tensile property has obtained improving greatly, and is lightweight, is fit to be easy to carry and reuse; Secondly, adopt the braiding of multiply tinned copper wire as anti-interference element, make cable satisfy the requirement of environment for use; Thereby solved the problems such as foreign technology barrier, whole degree of prospecting be lower, offshore oil drilling will be one of important strategic succeeding region of China's 21st century oil and gas industry, have very wide exploration prospect.
