Abstract
A diameter-changing cable comprises an insulating cable core in the center and a steel wire layer which is arranged outside the insulating cable core. The steel wire layer has a diameter-changing structure in which diameters are changed segmentally. According to the diameter-changing cable provided by the utility model, a structure of different thicknesses is adopted by the segments of the external steel wire layer, such that the whole cable has a diameter-changing structure in which diameters are changed segmentally. A structure of an inconvenient diameter of the traditional cable is changed, the process cost is reduced (about 3000 yuan can be saved for every km), effectiveness of an under well operation is increased, practicability of working under the well in a complex environment is improved, energy saving and environmental protection are realized and the cable is suitable for operations in large deviated wells and horizontal wells.
Description
Technical field
The present invention relates in field of telecommunications cables especially a kind of down-hole exploration cable.
Background technology
The important function of down-hole exploration cable is exactly to carry various downhole probes, transmit various signals between ground control system and the downhole instrument, obtain the depth location of down-hole information.It is as shown in Figure 1 to survey the construction of cable under the conventional well, and insulation cable core 2 outsides are provided with steel wire floor 1, the inconvenience of steel wire floor 1 thickness, thus whole cable size is inconvenient.The isometrical cable cost of this traditional handicraft is high, and weight is big, is not suitable for super large inclined shaft and horizontal well operation, and insulating material quality problems or heat resistance are relatively poor, cause insulating barrier aging very fast, and the cable core insulating capacity descends.
The utility model content
In order to overcome above-mentioned deficiency and the defective that exploration cable exists under the conventional well, the utility model provides a kind of reducing cable that is applicable to super large inclined shaft and horizontal well operation.
The utility model for realizing the technical scheme that above-mentioned purpose adopted is: reducing cable, comprise that the insulation cable core, the insulation cable core outside that are positioned at the center are provided with steel wire floor, and steel wire floor is the variable-diameter structure that the diameter segmentation changes.
Said insulation cable core comprises conduction cable core and insulating barrier, and the conduction cable core is a copper wire.
The reducing cable of the utility model, the structure of different-thickness is adopted in the segmentation of outer wires layer, thereby makes whole cable be the variable-diameter structure that the diameter segmentation changes; Change the structure of traditional cable diameter inconvenience, reduced the technology cost, about about 3000 yuan of every km escapable cost; Increase the actual effect of underground work; Improve the practicality of down-hole complex environment operation, energy-conserving and environment-protective are applicable to super large inclined shaft and horizontal well operation.
Description of drawings
Fig. 1 is the structure chart of traditional cable.
Fig. 2 is the structure chart of the reducing cable of the utility model.
Embodiment
The steel pipe construction of cable of the utility model is as shown in Figure 2, and reducing cable comprises the insulation cable core 2 that is positioned at the center, insulation cable core 2) outside is provided with steel wire floor 1, and steel wire floor 1 is the variable-diameter structure that the diameter segmentation changes.Armour divides steel wire of internal layer and cover wire, the armouring wire internal layer be dextrorotation around, skin be left-handed around, this mode can strengthen the anti-twisting property of cable.Insulation cable core 2 comprises conduction cable core and insulating barrier, and the conduction cable core adopts the coiling of high-quality copper wire to form.
Traditional cable in use, isometrical cable cost is high, weight is big, is not suitable for super large inclined shaft and horizontal well operation.The reducing cable of the utility model, the structure of different-thickness is adopted in the segmentation of outer wires layer, thereby makes whole cable be the variable-diameter structure that the diameter segmentation changes; Change the structure of traditional cable diameter inconvenience, reduced the technology cost, about about 3000 yuan of every km escapable cost; Increase the actual effect of underground work; Improve the practicality of down-hole complex environment operation, energy-conserving and environment-protective are applicable to super large inclined shaft and horizontal well operation.Traditional insulating material quality problems or heat resistance are relatively poor; Cause insulating barrier aging very fast; The cable core insulating capacity descends; The insulating barrier of the utility model cable adopts the fluoroplastics, polypropylene of electric property and better mechanical property, too material such as fluon is processed, and has the characteristic of oil resistant air water and soda acid salt corrosion, increases the service life greatly.
Claims (2)
1. reducing cable is characterized in that: comprise that the insulation cable core (2), insulation cable core (2) outside that are positioned at the center are provided with steel wire floor (1), steel wire floor (1) is the variable-diameter structure that the diameter segmentation changes.
2. reducing cable according to claim 1 is characterized in that: said insulation cable core (2) comprises conduction cable core and insulating barrier, and the conduction cable core is a copper wire.
