Abstract
The utility model discloses a sensing optical cable for oil well detection, which comprises a stainless steel pipe (2) and at least two optical fibers (1) located in the stainless steel pipe (2). Filling materials (3) are arranged between the inner wall of the stainless steel pipe (2) and the optical fibers (1), and a group of reinforcing steel wires (4) are twisted on the outside of the stainless steel pipe (2) in spiral twisting mode. The sensor cable for the oil well detection has excellent performances of being resistant to temperature as high as 600DEG C, tensile force over 10000N, pressure over 10000N, corrosion, and geomagnetism and geoelectricity interference, thereby being applicable to severe environment such as oil wells and the like to measure environment parameters of bore holes and well sites and broadening application fields of optical fiber sensors.
Description
Technical field
The utility model relates to a kind of optical cable, particularly relates to a kind of sensing optic cable that oil well is surveyed that is used for.
Background technology
Optical fiber sensing technology is to follow the development of Fibre Optical Communication Technology the seventies in 20th century and the novel sensing technology that develops rapidly.More external developed countries acquire a great achievement to the applied research of optical fiber sensing technology, and many optical fiber sensing systems are practicability, becomes the commodity that substitute traditional sensors.In the Oilfield developing process, people need know that in production fluid or the injecting process about the holding property of in-hole fluid and the particulars of state, this will use oil well logging, and its reliability and accuracy are vital.And traditional electronics based sensor can't be worked under down-hole rugged environment such as high temperature, high pressure, the ground electrical interference of burn into earth magnetism.Fibre Optical Sensor can overcome these difficulties, it is insensitive and can bear extreme condition to electromagnetic interference (EMI), comprise high temperature, high pressure (more than tens MPas) and strong impact and vibration, can measure pit shaft and well site environmental parameter accurately, simultaneously, Fibre Optical Sensor has the distributed measurement ability, can measure measured space distribution, provides profile information.And the Fibre Optical Sensor cross-sectional area is little, and profile is short, and it is minimum to take up space in pit shaft.
The utility model content
The utility model purpose is to overcome the deficiencies in the prior art, and a kind of application of opening up Fibre Optical Sensor is provided, and is high temperature resistant, tension, compressive strength height, the sensing optic cable that is used for the oil well detection of anticorrosive, anti-earth magnetism ground electrical interference.
The purpose of this utility model is achieved through the following technical solutions: be used for the sensing optic cable that oil well is surveyed, it comprises stainless-steel tube and is positioned at least 2 optical fiber of stainless-steel tube, be provided with packing material between stainless steel inside pipe wall and the optical fiber, stainless-steel tube is outer to have one group to strengthen steel wire so that spiral strand mode is stranded.
Described optical fiber is any one of common multimode, single-mode fiber, polyimide coated fiber, coating metal optical fiber.
Described packing material is any one of glass fibre, aramid yarn fiber.
Described reinforcement steel wire is any one of low-carbon (LC) lower strength wire of the high-carbon high-tensile steel wires of stainless steel wire, zinc-plated or phosphatization, zinc-plated or phosphatization.
The utlity model has anti-up to 600 ℃ of high temperature, anti-10000N with upper pulling force, anti-10000N with excellent properties such as upward pressure, the ground electrical interference of anticorrosive, anti-earth magnetism, be applicable to the environmental parameter of measuring pit shaft and well site in the rugged surroundings such as oil well, expanded the application of Fibre Optical Sensor.
