Abstract
The utility model discloses a kind of oil well temperature measuring optical cable, including light unit and outer insulating material layer, it is characterised in that：The light unit includes the aluminium lamination of stainless steel tube, the optical fiber and extrusion cladding being arranged in stainless steel tube outside stainless steel tube, one layer of steel band is at least coated with outside the light unit, one layer of interior insulation material layer is at least coated with outside the steel band, the outer insulating material layer is coated on outside interior insulation material layer.Advantage of the present utility model is as follows：1. aluminium lamination is continuous extrusion, has good air-tightness, it is ensured that internal steel pipe safety；2. steel band has good decay resistance；3. multi-layer insulation causes that oil well cable has the characteristic of the resistance to side pressure of high-temperature-resistant high-pressure-resistant；4. optical cable can according to actual application environment feature select optical cable profile, can Reusability can greatly reduce use cost.
Description
Technical field
The utility model is related to cable configuration technical field, specially a kind of oil well temperature measuring optical cable.
Background technology
With the development of Fibre Optical Communication Technology, optical fiber is more and more applied to oil well detection and measurement, and is not only
Producing well.Existing oil well temperature measuring optical cable is limited to structure and technological level, causes that cable strength is low, tolerable temperature is low, anti-side
Press poor performance, poor corrosion resistance, can not frequently use repeatedly, use cost is high.
The content of the invention
The purpose of this utility model is to provide a kind of oil well temperature measuring optical cable, and it has high temperature resistant, corrosion resistant high pressure resistant, high
The features such as erosion, lateral pressure resistant, Reusability, low cost.
The technical solution adopted in the utility model is：
A kind of oil well temperature measuring optical cable, including light unit and outer insulating material layer, the light unit include stainless steel tube, set
The aluminium lamination of optical fiber and extrusion cladding in stainless steel tube outside stainless steel tube, is at least coated with one layer of steel outside the light unit
Band, is at least coated with one layer of interior insulation material layer outside the steel band, the outer insulating material layer is coated on outside interior insulation material layer.
Further, outer insulating material layer is shaped as square or circular configuration.
Further, the steel band is 304 or 316L or the materials of Incoloy 825.
Further, the outer insulating material layer is that high-temperature insulation material passes through extrusion cladding in interior insulation material layer
Outward.
Further, the interior insulation material layer be high-temperature insulation material by extrusion cladding outside steel band.
Advantage of the present utility model is as follows：
1. aluminium lamination is continuous extrusion, has good air-tightness, it is ensured that internal steel pipe safety；
2. steel band has good decay resistance；
3. multi-layer insulation causes that oil well cable has the characteristic of the resistance to side pressure of high-temperature-resistant high-pressure-resistant；
4. optical cable can select optical cable profile according to actual application environment feature, can Reusability can greatly reduce and use
Cost.
