Abstract

The utility model relates to log steel cables formed by bundling multiple steel wires. The utility model is characterized in that the external surface of the bundling steel wires is bundled with an antiwear layer with smooth external surface. The utility model has the advantages that after the external surface of the steel cable is processed in a smooth mode, the steel cable can not discharge well pressure when moving up and down at a closed hole of a well head; the steel cable is bundled by antiwear materials, which can strengthen the strength of the steel cable; moreover, the steel wires can be prevented from breaking and thrusting resulted from the contact with obstacles under the well.

Description

A kind of Logging steel cable
The utility model relates to a kind of Logging steel cable that uses when under surveying oil well related parameter being arranged.
Visit in the oil well process adopting, need be under with the oil well closed state to the various parameters in down-hole detect, record.For this reason, traditional method is that the instrument for measuring and recording device is delivered to the down-hole with the closed hole that a steel wire binds, offers by well head, and according to surveying the record needs, the upper and lower steel wire of constantly pumping is to change instrument place height, position then.But because the downhole conditions complexity, usually occur that steel wire is worn, tensile phenomenon in the practice, damage, cause a large amount of economic losses thereby the instrument for measuring and recording device is fallen in the well.
For addressing the above problem, there is the people to be twisted into a wirerope at present and replaces individual wire to hang sending instrument to the down-hole with many steel wires.This way has lowered the probability of instrument drop really greatly, but but cause other problem: airtight side by side in the middle of the wirerope that is twisted into steel wire, outer surface is also rough, therefore when operate, just down-hole pressure is oozed and release, just distortion of the survey relevant supplemental characteristic recorded like this by closed pore; Whole wirerope be frangibility not, but a certain steel wire still often fractures in the wirerope, and in case one or a few steel wire that broken, disconnected quarrel is just outwards stung out, and this moment, whole wirerope can't move with regard to being easy to be stuck in the somewhere, down-hole again.
The utility model purpose is: overcome the deficiency of prior art, provide a kind of instrument for measuring and recording device that can guarantee can not come off, can guarantee again to survey the distortionless Logging steel cable of record data easily.
The utility model is achieved in that a kind of Logging steel cable, is formed by many steel wire boundlings, it is characterized in that: the wearing layer that is surrounded by smooth outer surface at steel wire boundling outer surface.
Also can realize the utility model like this: the high-abrasive material that steel wire boundling appearance bread is filled between per two adjacent wires in the steel wire boundling.Lead with insulating barrier is arranged in steel tendon.
The utility model advantage is: the wirerope appearance by smooth treatment after, do not move up and down at well head closed hole place just can not to ooze and let out well and press; Adopt high-abrasive material that wirerope is wrapped, can strengthen the intensity of wirerope greatly, also can prevent that steel wire from directly contacting and fractureing, sting out with the down-hole barrier.
Fig. 1 is the wirerope cross-sectional structure schematic diagram of the utility model embodiment 1.
Fig. 2 is the wirerope cross-sectional structure schematic diagram of the utility model embodiment 2.
Fig. 3 is the wirerope cross-sectional structure schematic diagram of the utility model embodiment 3.
Fig. 4 is the wirerope cross-sectional structure schematic diagram of the utility model embodiment 4.
Below in conjunction with drawings and Examples the utility model is done further narration:
As shown in the figure, being all that embodiment 1~2 shows only works the wirerope of tiing the logging equipment effect, all is to be made of many boundling steel wires 1 and the smooth outer wear layer 2 that wraps in steel wire boundling outer surface.Wherein the wearing layer 2 of example 1 is to adopt plastics to extrude the plastic material bag that technology will have an anti-wear performance to realize to the steel wire boundling; The wearing layer 2 of example 2 also is to adopt plastics to extrude technology wear resistant plastic material is not only wrapped steel wire boundling outer surface, thereby but also is filled into the intensity of further strengthening wirerope between per two adjacent wires in the steel wire boundling.In fact the difference of wearing layer structure extrudes mould by change and can realize in the example 1 and 2.
Embodiment 3~4 shows be not only have the effect of tiing and logging equipment can be surveyed steel cable structure that the record signal be real-time transmitted to aboveground ground, they have also all comprised many ordinary steel wire 1, the wearing layer 2 of steel wire boundling outsourcing, the conductor 3 that is positioned at steel wire boundling center and insulating barrier 4 thereof.What the two was different is: the wearing layer 2 of example 3 just extrudes steel wire boundling outer surface, and the wearing layer of example 4 not only extrudes steel wire boundling outer surface, and high-abrasive material also is filled between per two adjacent wires and lead and every adjacent steel wire between.In example 4 this structures, between every steel wire and lead all at regular intervals be filled between thing across, therefore if the material of selecting not only wear-resisting but also insulation for use as layer 2, conductor 3 outer surfaces just do not need to have wrapped up in insulating barrier 4 more so.
