Abstract
The invention relates to an ultralow-impedance and super shale-gas-resistant detection cable which comprises a plurality of conductors. Each conductor is externally wrapped through co-extrusion of an insulation layer and a semi-conduction inner shielding layer in a double-layer mode to form an insulation core, a cable core formed by the insulation cores is externally wrapped through extrusion of a semi-conduction outer shielding layer, and the semi-conduction outer shielding layer is externally provided with an anticorrosion armored protective layer. The detection cable has the advantages of reasonable and simple structure, easy production and manufacture, low cost, good application performance and convenient installation. Besides, the detection cable also has multiple functions of pressure resistance, interference resistance, static electricity resistance, high temperature resistance, corrosion resistance, water resistance, external-force impact resistance and the like, and integrates functions of measurement and control, monitoring signal transmission and protection. The detection cable is adaptive to operation of various oil and gas wells, such as well logging, perforating, core taking and the like, and is also adaptive to sea investigation, rivers and bays, water conservancy hydrographic survey, and such operation systems as geothermal wells and the like. Furthermore, the detection cable can also serve as a heavy hanging instrument measurement connecting line, can effectively suppress external electric and magnetic field interference and can resist corrosion of various harmful substances.
Description
Technical field
The present invention relates to a kind of exploration cable, particularly relate to the superpower anti-shale gas exploration cable of a kind of super-low impedance.
Background technology
Under the overall situation that global economy situation slows down, China's oil equipment field still remains situation that is steadily increasing, that rise against the tendency.Exploration cable is as the important tie of oil-gas exploration platform information system, need signal to gather, geological prospecting, video imaging, instrument hang the function such as heavily and be integrated in one, synchronously complete, but also need the rupture pull force of carrying to be greater than more than 80KN, need effectively to suppress extraneous electricity, magnetic interference, the corrosion of anti-various harmful substance, could meet the needs of oil-gas exploration.
Summary of the invention
The present invention provides a kind of compact conformation, the superpower anti-shale gas exploration cable of withstand voltage anti-interference, high temperature resistant, corrosion-resistant, that stable signal transmission, production cost are low super-low impedance to overcome the above problems.
Technical scheme of the present invention is: described cable comprises some conductors, the outer double-layer coextrusion insulated layer of this conductor and semiconductive internal shield form insulated wire cores, extrude semiconductive outer shielding layer outside the cable core formed after described insulated wire cores stranding, outside described semiconductive outer shielding layer, be provided with anticorrosion armouring sheath.
Described conductor is the 2nd class conductor meeting GB/T3956-2008 requirement, and this conductor is fixed length stranded high-purity red copper conductor, and resistance is less than 29.1 Ω/km, and electric capacity is less than 124uf/km.
Described insulating barrier is perfluoroethylene-propylene insulating barrier.
Described anticorrosion armouring sheath is the two-layer high-carbon zinc-coated wire layer of oppositely braiding, comprises inner steel wire layer and outer steel wire layer, is filled with high-temperature resistant anti-corrosive grease between two-layer steel wire floor.
The present invention is simply rational in infrastructure, and manufacture easily, cost is low, and serviceability is good, easy for installation.It is multi-functional that cable has withstand voltage, anti-interference, antistatic, high temperature resistant, corrosion-resistant, waterproof, external force resistance impact etc., realizes observing and controlling, pilot signal transmission simultaneously, protects integrated feature.Be applicable to the well logging of all kinds of oil, gas well, perforation, get the operations such as core; Also be applicable to oceanographic survey, bay, river, water conservancy hydrographic survey, the operating systems such as geothermal well, as the heavy apparatus measures connecting line of extension, effectively can suppress extraneous electricity, magnetic interference, the corrosion of anti-various harmful substance.
