Abstract
The utility model discloses a novel polymer composite fiber well-logging cable. The novel polymer composite fiber well-logging cable comprises a conductive cable core (1), a cable core insulation layer (2), a filler (4), a braiding layer (3), a polymer composite fiber layer (5) and a rubber protection layer (6), wherein the polymer composite fiber layer (5) is wrapped outside the braiding layer (3), and the rubber protection layer (6) is wrapped outside the polymer composite fiber layer (5). The novel polymer composite fiber well-logging cable employs polymer composite fiber material as a base frame to replace an inner and outer double-layer steel wire armor of a bearing load detection well-logging cable and changes tensile force, acid and alkali resistance and corrosion resistance of a traditional well-logging cable, so the novel polymer composite fiber well-logging cable has advantages of operational convenience, higher temperature resistance, stronger corrosion resistance, longer service life, improved bearing load capacity, improved well-logging safety and high economic benefit.
Description
Technical field
The utility model relates to a kind of logging cable, is specifically related to the novel logging cable of a kind of polymer composite fiber, and main function is bearing tension, system power supply, signal transmission, severity control, be used for all kinds of oil, gas well well logging, perforation, get the operation such as core.
Background technology
Existing logging cable (bearing detection logging cable) generally is comprised of conduction cable core, cable core insulating barrier, charges, braid and armour protective layer, wherein armour protective layer adopts the steel wire of dual layer arrangement to twist in the opposite direction respectively strength, forms inside and outside double wire armor layer.There is following shortcoming in this logging cable: 1) pulling force has limitation: the general domestic logging cable pulling force limit is 8-9T, and according to the requirement of rules, the maximum pull of cable can not surpass 50% of new cable rated value.Calculate accordingly actual pulling force at 4-4.5T; Copper core can surpass fatigue strength, permanent deformation, cause distortion Z distortion when surpassing 75%, destroys ambroin, leak electricity short-circuit.2) traditional logging cable is steel wire because of material, Gu resistance to acids and bases is anticorrosive poor, thereby is subjected to salt solution or hydrogen sulfide corrosion in the oil well of reality, thereby makes the surface quick-wearing very between the armour, affects wireline cable life.3) logging cable all is two layers of unbalanced cable of steel wire torsion, and when pulling force strengthened, the cable trend stretched, diameter diminishes, rotates; When otherwise pulling force reduced, then shortening, diameter became large, opposite spin.All factors that harm that cables rotate freely are roots of damaging, so the cable armouring steel wire unclamps and be out of shape, and cause short dot thereby make armouring give insulating barrier with high pressure.4) logging cable all is two layers of steel wire high-temperature resistant water adjustment, surpasses set point of temperature and causes the insulating barrier distortion, finally causes conducting electricity short circuit between cable core and the armour.In addition, during the well logging of bearing detection logging cable, exist the slit between the outer armour of invar silk, the wellhead sealing difficulty is large, usually needs to adopt to dote on large wellhead blowout preventer and arrangement for crane machinery operation, and workload is large, wastes time and energy.
The utility model content
The purpose of this utility model is for deficiency of the prior art, and a kind of easy to operate, high temperature resistant, corrosion resistance, the longer novel logging cable of polymer composite fiber of life-span are provided.
For finishing above-mentioned purpose, the technical solution adopted in the utility model is: the novel logging cable of polymer composite fiber, comprise conduction cable core, cable core insulating barrier, charges, braid, it is characterized in that: also comprise polymer composite fiber layer and preventing rubber layer, at braid outer wrapping polymer composite fiber layer, wrapped preventing rubber layer outside the polymer composite fiber layer.
Preferably, described polymer composite fiber layer is any one in pbo fiber, Para-aromatic Aramide Fibre, coordination aramid fibre or the high modulus polyester fiber.
The utility model adopts the polymer composite fiber material as pedestal, the outer armour of inside and outside double-layer wire that replaces the bearing detection logging cable, change pulling force, the acid and alkali-resistance, anticorrosive of traditional logging cable, thereby make that the utility model is easy to operate, more high temperature resistant, corrosion resistance, life-span be longer, improved the fail safe of holding lotus ability and well logging, economic benefit is high.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is structural representation of the present utility model;
Among the figure: 1, conduction cable core, 2, the cable core insulating barrier, 3, braid, 4, charges, 5, the polymer composite fiber layer, 6, the preventing rubber layer.
Embodiment
As shown in Figure 1, the novel logging cable of polymer composite fiber is comprised of conduction cable core 1, cable core insulating barrier 2, charges 4, braid 3, polymer composite fiber layer 5 and preventing rubber layer 6.Conduction cable core 1 is comprised of one or a few core, and each root core is to be formed by certain direction is stranded by many copper conductors, and the conduction cable core should have alap resistance value.Cable core insulating barrier 2 wraps up conduction cable cores 1, has determined heat resistance and the electric property of conduction cable core 1, and insulating layer material is generally the chemical synthetic materials such as polyethylene, teflon.Braid 3 is the lining of armoured cable as total screen, and by cable conduction outer shielding, fiber material or strap is wrapped forms, its effect is that to prevent from conducting electricity cable core 1 impaired.Charges 4 are as sub-shield, are to be filled in the things such as conductive shielding layer around the conduction cable core 1 and tawny daylily fiber crops, cotton yarn.Polymer composite fiber layer 5 replaces the outer armour of inside and outside double-layer wire of bearing detection logging cable as the main body of the bearing load of logging cable, is wrapped in outside the braid 3.Polymer composite fiber layer 5 is any one in pbo fiber, Para-aromatic Aramide Fibre, coordination aramid fibre or the high modulus polyester fiber.Wherein, pbo fiber refers to Poly-p-phenylene benzobisthiazole (Poly-p-phenylene benzobisthiazole), and its finished product is zylon HM, zylon AS.Pbo fiber is a kind of high-performance fiber that is made by fiber spinning from crystalline state by the PBO polymer, compares with other high-performance fiber, and pbo fiber has higher specific strength, specific modulus and heat-proof combustion-resistant performance.Preventing rubber layer 6 is at polymer composite fiber layer 5 outer wrapped overcoat, is used for the moistureproof abrasionproof of logging cable.
Above embodiment only is used for explanation the utility model, but not is used for limiting the utility model, and the equivalent variations that those skilled in the art carry out above-described embodiment, replacement are all within the claim protection range.
