Abstract
The utility model provides a special steel wire armoured cable used for mining shale gas, belonging to the technical field of an armoured cable, wherein structurally, the center of the armoured cable is provided with an oxygen-free copper wire intertwisting conductor, outside the oxygen-free copper wire intertwisting conductor there is provided an inner layer steel wire intertwisting armoured layer and an outer layer steel wire intertwisting armoured layer, and between the oxygen-free copper wire intertwisting conductor and the inner layer steel wire intertwisting armoured layer there is provided a high temperature insulating extrusion filling layer. The special steel wire armoured cable used for mining shale gas can be used for exploitation and logging of a deep shale gas, can be excellently applied to the field of a compact rock mining device, such as shale, and a power transmission and work device, can play an important role in the process of mining the compact gas layer, and can forcefully ensure safe production and safe work.
Description
Technical field
The utility model relates to the armoured cable technical field, specifically a kind of shale gas special steel wire armoured cable.
Background technology
Shale gas is exploitation natural gas out from the rammell, is a kind of important unconventional gas resource.The formation of shale gas and enrichment have the characteristics of self uniqueness, often are distributed in the basin that thickness is larger, in widespread shale hydrocarbon source rock formation.Compare than conventional gas, shale gas exploitation has advantages of that production life of well is long and the production cycle is long, and most of aerogenesis shale has a very wide distribution, thickness is large, and general gassiness, and this makes the shale gas well can be chronically with stable speed aerogenesis.The shale gas production technique mainly comprises horizontal well technology and multiple fracturing technology, riverfrac treatment technology, multiple fracturing technique and up-to-date synchronous fracturing technique, and these technology are just improving constantly the shale gas well yield.The cable that uses in the operation of shale gas exploitation requires high, common cable can't use on mining operations and development equipment, and the shale gas private cable under prior art exists many deficiencies and defective, can not well satisfy the requirement of the special development operation of shale gas.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of shale gas special steel wire armoured cable is provided.
The technical solution of the utility model realizes in the following manner, this shale gas special steel wire armoured cable, its structure is that the center of this armoured cable is provided with the copper free wire stranded conductor, copper free wire stranded conductor periphery is provided with the stranded armour of steel wire of internal layer and the stranded armour of cover wire, and the space-filling between the stranded armour of copper free wire stranded conductor and steel wire of internal layer is provided with high-temperature insulation and extrudes filling.
The stranded armour of cover wire periphery is provided with protective sleeve, between the stranded armour of protective sleeve and cover wire, between the stranded armour of cover wire and the stranded armour of steel wire of internal layer and the space between the stranded armour of steel wire of internal layer and copper free wire stranded conductor is provided with high-temperature insulation and extrudes filling.
The beneficial effect that the utility model compared with prior art produces is:
this shale gas special steel wire armoured cable is used as advanced shale gas exploitation well logging steel wire armored cable, cable conductor adopts that copper free wire is stranded to be formed, its cross-sectional area of conductor is long-pending is to calculate according to shale gas well relevant data to form, import F46 high-temperature insulation is extruded, the ectonexine armouring selects the meticulous armouring of 316L stainless steel steel wire to form, outer diameter parameters appointment supporting according to the shale gas equipment requirement, different from other wire diameters, can well be applied in the winning apparatus and electric power conveying and operating apparatus of this class tight rock of shale, can play a significant role in the mining operations of tight gas reservoir gas, can strong guarantee safety in production and safety work.
This shale gas special steel wire armoured cable is reasonable in design, simple in structure, safe and reliable, easy to use, be easy to safeguard, has good value for applications.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Mark in accompanying drawing represents respectively:
1, copper free wire stranded conductor, 2, the stranded armour of steel wire of internal layer, 3, the stranded armour of cover wire, 4, high-temperature insulation extrudes filling, 5, protective sleeve.
Embodiment
Below in conjunction with accompanying drawing, shale gas special steel wire armoured cable of the present utility model is described in detail below.
as shown in drawings, shale gas special steel wire armoured cable of the present utility model, its structure is that the center of this armoured cable is provided with the copper free wire stranded conductor, copper free wire stranded conductor periphery is provided with the stranded armour of steel wire of internal layer and the stranded armour of cover wire, the stranded armour of cover wire periphery is provided with protective sleeve, between the stranded armour of protective sleeve and cover wire, between the stranded armour of cover wire and the stranded armour of steel wire of internal layer and the space between the stranded armour of steel wire of internal layer and copper free wire stranded conductor is provided with high-temperature insulation and extrudes filling.
This shale gas special steel wire armoured cable is used as advanced shale gas exploitation well logging steel wire armored cable, cable conductor adopts that copper free wire is stranded to be formed, its cross-sectional area of conductor is long-pending is to calculate according to shale gas well relevant data to form, import F46 high-temperature insulation is extruded, the ectonexine armouring selects the meticulous armouring of 316L stainless steel steel wire to form, outer diameter parameters appointment supporting according to the shale gas equipment requirement, different from other wire diameters.
