Description
Technical field
The present invention relates to field of cables, in particular to a kind of WMF series closed type charge bearing detecting 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.
But it is that circular steel wire arranging surrounds that armor, which is all by one group of cross section, inside and outside traditional charge bearing detecting cable
It forms, it is larger that there are gaps between steel wire, and the friction area between neighboring armatures layer steel wire is very small, when steel wire is by ambient pressure
When, there is the trend squeezed to centre in the steel wires of two sides, then the intermediate steel wire being extruded will stress protrude from original armor
Overall structure, easily rubbed, the globality of armor caused to be destroyed, the depression of bearing force of cable.Meanwhile " jumping silk ",
Abnormity is almost changed by original for circle in its section of cable after " bulge ", can just be hampered during going into the well, block
Stagnant situation.
Because the gap between steel wire is larger, after cable is gone into the well, underground oil liquid can overflow to well face between steel wire gap, make
At pollution in wide area.
As another biggish drawback of gap, the leakproofness of cable sheath is poor, also results in external corrosion liquid
Corrode inside cable, influences cable normal service life.
Therefore, a kind of cable of brand new how is designed, is that those skilled in the art need to solve to solve the above problems
Certainly.
Summary of the invention
The purpose of the present invention is to overcome above-mentioned the deficiencies in the prior art, provide a kind of WMF series closed type bearing detection

Outside insulating layer, the gap between adjacent round wire is poured filling, sealant layer and round wire by sealant layer
Collectively form the closed structure that section is circular ring shape；
The armoured layer is that round and dumbbell shape steel wire is alternatively arranged twisted ring set and forms by section, more circles and
Also Formation cross-section is circular closed structure to armoured layer after dumbbell shape steel wire ring set, and dumb-bell shape steel wire is filled with adjacent circular
Gap between steel wire.
Preferably, the copper stranded conductor is single structure, and single structure is external after being twisted together using multilayer copper stranded conductor
Insulating layer package, adjacent layer copper stranded conductor orientation are opposite.
Alternatively, the copper stranded conductor twists together for three-core structure, the copper stranded conductor of any core is wrapped up by insulating layer ring set,
Gap after the insulating layer of adjacent core is twisted between inner armor layer is filled object and is filled, and filler selects cotton thread or poly- third
Alkene.
Preferably, the insulating layer is modified polypropene or fluoroplastics material.
Preferably, the insulating layer with a thickness of 0.55-1.2mm.
Preferably, the diameter of the round wire of inner armor layer is 0.4-1.0mm.

1.0mm。
Preferably, filling is cast with sealant between inner armor layer and outer layer armor, is respectively formed inside and outside armor close
Close structure.
Sealant uses EVA hot-melt adhesive.
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: the leakproofness of the cable also improved while improving cable bearing capacity and reliable
Property, it is specific as follows.
(1) armoured layer greatly reduces the gap between armouring wire, ectonexine using round and dumbbell shaped steel wire
Sealant is coated between armor, inside and outside armor is made to be respectively formed closed structure, and round and dumbbell shaped steel wire effectively increases steel
The friction area of silk, cable wear resistance can improve, and the bearing capacity retention time is long, improve the service life of cable indirectly,
The type cable can avoid the problem of steel wire leads to cable improper damage by phenomena such as " jump silk ", " bulge " simultaneously；
(2) armoured layer is increased compared to entirely with round steel wire using round and dumbbell shaped steel wire, sectional area, steel wire material
Under the same conditions, the bearing capacity of cable is greatly improved matter.
(3) 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；
(4) leakproofness of armor has great promotion for original cable inside and outside, can prevent oil spilling
While pollution, liquid corrosion object can be reduced and entered inside cable, prevent from being corroded inside cable, guarantee that the tension of cable is strong
Degree, improves the service life of cable, can simultaneously be effectively prevents downhole oil hydrorrhea from flowing to well face, form preferable guarantor to environment
Shield.
(5) adjacent layer steel wire orientation on the contrary, adjacent layer copper stranded conductor orientation on the contrary, have good not rotatory, securely, no
It easily scatters, the lay pitch is big, and structural stretch is small.
(6) cable core, that is, copper stranded conductor can transmit data-signal, the tension of real-time Transmission cable, underground temperature as data line
Degree, pressure etc. avoid blindly producing, improve working efficiency.
