Description
Technical field
The utility model is related to a kind of photoelectricity composite steel tube oil well detection cable, belongs to field of cable technology.
Background technology
Photoelectricity composite steel tube oil well detection cable is mainly used in the operations such as well logging, perforation, the coring of various Oil/gas Wells, now gives birth to
The photoelectricity composite steel tube detection cable of product mainly uses metallic conductor core as holding wire, and its shortcoming is：Signal attenuation is big,
It is restricted using length（Using it is long when, because decay is too big, receiving instrument cannot resolved measurement signal）, it is impossible to carry out big
Depth（It is more than ten thousand metres）Measure；Because metallic conductor core density is big, cause cable to conduct oneself with dignity excessive, make the effective of cable
Bearing capacity is reduced significantly.
Meanwhile, existing oil well detection cable, mostly using steel wire multilayer reverse-winding as armour protective layer, while making
It is load bearing element, has the disadvantages that, on the one hand, due to using double-layer wire, cable weight is excessive, reduces cable itself
Weight capacity；On the other hand, wire armoring air-tightness and mechanical protection performance are bad, influence the service life of cable.
Utility model content
The utility model purpose is to provide a kind of photoelectricity composite steel tube oil well detection cable, and metallic conductor line is replaced with optical fiber
Core makes up the defect of existing detection cable as holding wire, replaces multilayer steel wire to protect by being protected using steel pipe, reduces cable
Deadweight, improves effective bearing capacity of cable, efficiently solves above mentioned problem present in background technology.
The technical solution of the utility model is：A kind of photoelectricity composite steel tube oil well detection cable, comprising built-in fiber, optical fiber
Outer steel pipe overcoat, factice for filling, sheath one, power line, sheath two and steel pipe overcoat, the built-in fiber, optical fiber
Outer steel pipe overcoat, sheath one are arranged in order to form optical fibre core from the inside to the outside, and factice for filling is filled with built-in fiber
Between the outer steel pipe overcoat of optical fiber, power line includes tinned copper conductor and insulating barrier, and winding is arranged on the outside of optical fibre core,
Sheath two extrudes the outside for being arranged on optical fibre core and power line, and steel pipe overcoat is arranged on the outside of sheath two.
The quantity of the built-in fiber is two or more than two.
The quantity of the power line is more than three cores or three cores.
The sheath one, the material of sheath two are the plastics or rubber of 230 DEG C of high temperature resistant.
The steel pipe thickness of the steel pipe overcoat is 2.0-3.5 millimeters.
The beneficial effects of the utility model are：Existing detection electricity is made up as holding wire instead of metallic conductor core using optical fiber
The defect of cable, reduces the decay of cable transmission signal, and optical fiber is decayed in transmission signal and is not more than 0.36dB/km（1310nm）,
The cable is set to carry out the measurement of big depth, it is to avoid cable will not cannot because signal attenuation is excessive when long length works
Normally measured work；Use stainless steel tube as the protective layer of optical fiber outside optical fiber, optical protective performance is good, and core will not go out
Existing crack conditions；Cable outermost Rotating fields replace the protection of multilayer steel wire using steel pipe protection, and steel pipe air-tightness is good, while having very
Good tension and anti-pressure measurement performance, improves the protective capacities of cable, improves the service life of cable.
