Description

A kind of cable penetration device of cable-passing packer
Technical field
The utility model relates to the cable penetration device of petroleum industry submerged electric oil pump well, especially a kind of cable-passing packer Cable penetration device, the whole crossing construction of the flat power cable suitable for cable-passing packer meeting well control requirement premise Under, effectively enhance cable penetration quality, eliminate the structure problem for causing cable fault, extends electric pump well and be excused from a college course the phase.
Background technique
The complete well of offshore oil production mostly uses electric submersible pump well-completing process, due to well control safety in terms of requirement, it is also necessary to it is mating Oil pipe and oil jacket annulus are closed using storm valve, cable-passing packer.Traditional cable-passing packer penetration device It is made of penetration device ontology, steel pressure pad, rubber press pad and penetration device pressure cap, is divided into conventional pass through according to the difference for the mode of passing through It is integrally passed through with end cable.Routine is passed through there are cable connection packet, and end cable integrally passes through no cable connection packet.It is above-mentioned Two kinds of modes of passing through require to strip Exterior cable armour skin in construction, and what is used is all that threephase cable is penetrated pressure pad, on Press the cap mode that compressing rubber pressure pad makes its deformation realize sealing simultaneously.Flat power cable is metal armour skin from outside to inside, resistance to Grind winding layer, sheet lead, insulating layer, copper core.Need to strip metal armour skin, wear-resisting winding layer using traditional penetration device, by metal pressure Pad and rubber seal pressure pad have from 3 strand to be passed through outside the cable of sheet lead.Penetration device pressure cap makes metal pressure pad pressure in screwing operations Contracting rubber seal pressure pad makes its deformation ensure to seal, and metal pressure pad and rubber seal pressure pad, which exist, during screwing pressure cap rotates Phenomenon, metal pressure pad and rubber seal pressure pad misplace since frictional force difference causes to exist between the two, and cable sheet lead is squeezed Deformation punctures cable insulation, causes cable insulation to reduce, punctures easily at this in the production process of submersible electric pump and burn.
Therefore it needs to invent and a kind of crosses cable envelope without strip that flat cable armour skin can carry out that end cable integrally passes through Every device penetration device.
Summary of the invention
The purpose of the utility model is to provide a kind of cable penetration devices of cable-passing packer, without stripping flat cable armour skin I.e. implementable end cable entirety crossing construction, under the premise of meeting well control requirement, effectively improve cable passes through quality, prolongs Long submerged electric oil pump well is excused from a college course the phase.
Purpose of the utility model is realized as follows: a kind of cable penetration device of cable-passing packer includes pressure cap and this Body, pressure cap are threadedly coupled with ontology, and the inner cavity lower part of ontology is equipped with limited step, are equipped in the inner cavity between ontology and pressure cap Rubber seal cylinder.
The shape of the rubber seal cylinder is the armour skin shape knot of cylindrical, its inner cavity cavity wall structure and flat power cable Structure is identical, the upper lumen of rubber seal cylinder be round cavity, middle part inner cavity be with upper lumen with wide ribbon inner cavity, under Portion inner cavity is conical cavity.
Compared with prior art, the significant using effect of the utility model is: the utility model is mounted with rubber in the body Glue sealing drum, shape are that the cylindrical, structure of its inner cavity cavity wall is identical as the armour skin contour structures of flat power cable, flat power The armour skin of cable can be mutually embedding with the inner cavity of rubber seal cylinder, ensure that the reliability of sealing, without stripping flat cable armour skin i.e. Implementable end cable entirety crossing construction.The cable armour skin not stripped forms effective protection to cable, seals realizing Under the premise of the injury of cable will be minimized, significantly improve cable passes through quality, avoids the damage of cable, prevents A possibility that burning from breakage breakdown, effectively extend submerged electric oil pump well is excused from a college course the phase, significantly reduces production cost, has There is significant using effect and apparent economic benefit can be generated.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is described in detail below in conjunction with attached drawing, not limits the protection scope of the utility model.It is as described below to be only The preferred embodiment of the utility model, other use the equivalence changes of the utility model, should belong to the protection of the utility model Range.
Referring to Fig. 1, a kind of cable penetration device of cable-passing packer includes pressure cap 2 and ontology 1, pressure cap 2 and 1 screw thread of ontology Connection, the inner cavity lower part of ontology 1 are equipped with limited step, rubber seal cylinder 3 are housed in the inner cavity between ontology 1 and pressure cap 2.
The shape of the rubber seal cylinder 3 is the armour skin shape of cylindrical, its inner cavity cavity wall structure and flat power cable Structure is identical, and it is with upper lumen in wide ribbon that the upper lumen of rubber seal cylinder 3, which is round cavity, middle part inner cavity, Chamber, lower lumen are conical cavities.In the screwing operations of pressure cap 2 and ontology 1, the conical cavity of rubber seal cylinder 3 exists Cable-passing packer seals under following casing annulus pressure effect, and rubber seal cylinder 3 can be made to realize radial deformation, squeezes and seals Flat power cable therein.
Hole for injecting glue 4 is additionally provided in the tube body of the ontology 1, the hole for injecting glue 4 is located at the ontology 1 equipped with rubber seal cylinder 3 Tube body position is simultaneously threadedly coupled with equipped with the injecting glue connector 5 of ball-and-seat, by the injecting glue connector 5 can to rubber seal cylinder 3 and Sealant is injected in installation gap between ontology 1.
The valve seat of ball-and-seat in the injecting glue connector 5 is located at the top of valve ball, can make to inject rubber seal cylinder 3 and ontology The sealant installed in gap between 1 can not be flowed back by injecting glue connector 5.
The injecting glue connector 5 is connect with injecting glue tool.
