Description
Technical field
The present invention relates to field of cables, in particular to a kind of photoelectric composite charging detection cable.
Background technique
With the fast development of wire logging techniques and the appearance of novel logger, it is matched use hold lotus
It is improved day by day to detect cable production technology, this kind of cable is mainly used for all kinds of oil, gas well as weight apparatus measures connecting line is hung
The operations such as well logging, perforation, coring；It can also be used for oceanographic survey, river, bay, water conservancy, hydrographic survey and coal field geology are surveyed
Spy, geothermal logging etc..
In above-mentioned cable, there are deep-well cable, ultradeep well cable and special ultradeep well cable respectively.The load-bearing capacity of cable,
Anti-overflow performance, the convenience installed and used and signal transmission capabilities play a decisive role to cable quality.
Because the gap between armoured layer and the steel wire of inner armor layer is larger, the leakproofness of cable sheath is poor, meeting
Cause to influence cable normal service life inside external corrosion liquid corrosion cable.Therefore it needs to improve.
Summary of the invention
The purpose of the present invention is to overcome above-mentioned the deficiencies in the prior art, providing a kind of photoelectric composite charging detection cable,
Improve cable bearing capacity, electric conductivity, leakproofness and the reliability of the cable of raising.
The present invention adopts the following technical scheme:
A kind of photoelectric composite charging detection cable, including successively wrap up from outside to inside insulating jacket layer, steel wire organization level,
Insulating layer, steel pipe, fiber paste, optical fiber, insulating jacket layer outside, which is twisted ring set, inner armor layer, there is outer twisted ring set outside inner armor layer
Armor；The inner armor layer, which is that circular steel wire is twisted by more sections, to be located on outside insulating jacket layer, described armoured
Layer, which is that circular steel wire is twisted by more sections, to be located on outside inner armor layer.
The insulating layer is made of modified polypropene or fluoroplastics material.
Insulating jacket layer is made of polypropylene or Teflon material.
The insulating layer with a thickness of 0.6-1.1mm.
The diameter of the round wire of the inner armor layer is 0.5-1.3mm.
The diameter of the round wire of armoured layer is 0.5-1.3mm.
Unanimously leftward or rightward spiral is twisted for the steel wire of inner armor layer；Armoured layer is opposite with the inner armor layer hand of spiral.
The beneficial effects of the present invention are: electric conductivity, the leakproofness of the cable also improved while improving cable bearing capacity
It is specific as follows with reliability.
(1) optical fiber is that the effect for transmitting signal solves traditional measurement method for measuring downhole temperature, pressure, flow
In multiple sensors, the longer problem of instrument.Fiber paste uses high temperature resistant fiber paste.Copper wire, shielding and power supply, shielding make to transmit signal
It is purer, reduce interference.Copper wire power supply, provides kinetic energy for underground equipment, and copper wire is softer, does not influence the flexible of cable
Property.
(2) insulating jacket layer makes cable form closed structure, not only can play insulating effect, and leakproofness phase for copper wire
Have great promotion for existing cable, while can prevent oil spill, can reduce liquid corrosion object into
Enter inside cable, prevents from being corroded inside cable, guarantee the tensile strength of cable, improve the service life of cable.
(3) the steel wire orientation of armoured layer and inner armor layer securely, is not easy to scatter on the contrary, with good not rotatory,
The lay pitch is big, and structural stretch is small.
(4) steel pipe has certain hardness, cable can be made to be held round, and can protect optical fiber.
(5) cable smooth in appearance is wear-resisting, formed pure circle structure, can prevent in use cable be hampered, meets block ask
The appearance of topic.
Detailed description of the invention
Attached drawing 1 is cross-sectional view of the invention.
Wherein: 1 insulating jacket layer, 2 steel wire organization levels, 3 insulating layers, 4 steel pipes, 5 fiber pastes, 6 optical fiber, 7 inner armor layers, outside 8
Armor.
