Abstract
The utility model discloses a chemical corrosion resistant sensing optical cable, which comprises at least one optical fiber (1), an inner stainless steel pipe layer (2), an inner corrosion resistant layer (4) made of an acid-resistant, alkaline-resistant and oil-proof macromolecule material, an outer stainless steel pipe layer (5) and an outer corrosion resistant layer (6) made of an acid-resistant, alkaline-resistant and oil-proof macromolecule material, wherein each optical fiber (1) is positioned in the inner stainless steel pipe layer (2); a filler (3) is arranged between the inner stainless steel pipe layer (2) and the optical fiber (1); the inner corrosion resistant layer (4) wraps the inner stainless steel pipe layer; and the outer stainless steel pipe layer (5) and the outer corrosion resistant layer (6) are sequentially arranged outside the inner corrosion resistant layer (4). The utility model has the advantages that due to the two stainless steel pipe layers, the chemical corrosion resistant sensing optical cable is strong in tensile strength and compressive strength; the two corrosion resistant layers can resist chemical corrosion and oil; and the chemical corrosion resistant sensing optical cable is suitable to working under an oil well.
Description
Technical field
The utility model relates to a kind of optical cable, is specifically related to a kind of sensing optic cable of resistance to chemical attack.
Background technology
In the Oilfield developing process; The staff need know parameters such as hydrodynamic pressure and the temperature in the oil well; This need use sensor to measure, but traditional electronics based sensor can't be under the condition of down-hole high temperature, high pressure, deep-etching and magnetic interference doughtily operate as normal.Fibre Optical Sensor does not receive the interference in magnetic field of the earth, and cross-sectional area is little, is adapted at underground work, but high temperature resistant limited in one's ability with high pressure of existing light sensor, and not resistance to chemical attack.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, and the sensing optic cable of the resistance to chemical attack of a kind of high temperature resistant, high pressure and chemical corrosion is provided.
The purpose of the utility model realizes through following technical scheme:
Be used for the sensing optic cable that anti-high chemical corrosion oil well is surveyed; It comprises at least one optical fiber, interior stainless-steel tube layer, the interior anticorrosive coat that is made up of the macromolecular material of acid and alkali-resistance, oil resistant, outer stainless-steel tube layer and the external anti-corrosion layer that is made up of the macromolecular material of acid and alkali-resistance, oil resistant; Optical fiber is positioned at the stainless-steel tube layer; Be provided with filling material in the interior stainless-steel tube layer and between the optical fiber, anticorrosive coat in the outer coating of interior stainless-steel tube layer is disposed with outer stainless-steel tube layer and external anti-corrosion layer outside the interior anticorrosive coat.
Optical fiber is common multimode optical fiber, general single mode fiber, polyimide coated fiber or coating metal optical fiber.
Filling material is fine cream, inorganic fibre or organic fiber.
The advantage of the utility model is: be provided with two stainless-steel tube layers, tension, anti-pressure ability are strong; The resistance to chemical attack of two-layer anticorrosive coat ability, oil resistant; Be adapted at work under the oil well.
