Abstract
The utility model provides a sealing sleeve connected with a special cable, which is used for being connected with a round cable or a flat cable. The sealing sleeve connected with a special cable comprises a sleeve body and extending parts; one part of the sleeve body is hollow to form a hollow part; the other part of the sleeve body is solid; the solid part is a wire separation part; and three insulated holes are arranged in a penetrating mode on the wire separation part along the sleeve body length direction. As isolated extending parts are arranged and the joint of the special cable is connected outside the extending parts, the sealing ability of the special cable joint can be enhanced, and the insulated performance is improved.
Description
Technical field
The utility model relates to a kind of sealing shroud of stube cable, relates in particular to a kind of sealing shroud that connects special-shaped cable.
Background technology
Existing carbonate rock fractured cave type heavy crude reservoir has the feature of " two surpassing five height ", be the sticky warm flex point of crude oil dark, need the dark and thin oil blending visbreaking of lower pump to produce to need the characteristic of large discharge capacity to determine that electric submersible pump becomes the main lifting technology of viscous crude mechanical lift, and the submersible electric pump of its application is mainly through the anti-viscous crude submersible electric pump of deeply taking out of technological improvement.But since 2010, be subject to newly to drop into thicker (the average 510000mPa.s of crude oil dynamic viscosity of piece oil, mobile performance extreme difference), the impact of formation water salinity higher (average 200346mg/l), hydrogen sulfide content higher (average 141600ppm), well Wen Genggao (average 110 DEG C of 3500m place) and pressure higher (more than the average 30MPa in 3500m place), the viscous crude Electric Submersible Pump System well rate of lying shows significantly the trend rising, and finds by statistics: cable heteromorphic connector fault is to cause a lie factor of well of electric pump.Recover the oil two factories as example taking China Petrochemical Industry, and only 2011 because of cable heteromorphic connector fault cause lying well 10 wells time, account for 9.7% of total failed well number, cause 0.3901 ten thousand tons of production losses, and 0.1055 ten thousand tons of waste thin oils, increase by 668.9 ten thousand yuan of costs.
But cause cable heteromorphic connector failure rate main cause high, that useful life is short to have two aspects:
1) viscosity of crude is high, enters demand pump for meeting viscous crude, and pump is hung lower dark in 2800-3500m, and HTHP easily causes joint to ooze working fluid, thereby causes failure of insulation;
2) existing round cable is by three wire overall package with restrictive coating, and three wires of flat cable are independent encapsulation, be subject to structural limitations, round flat abnormity cable carries out effective sealing between cannot be to its insulating barrier and restrictive coating in the time connecting, after under cable lower going-into-well, well liquid and gas under high pressure directly infiltrate to surface of insulating layer from restrictive coating gap, make restrictive coating lose original isolation and safeguard function, cause oil-submersible cable insulation property fast-descending, reduce useful life.
Summary of the invention
In order to overcome the above problems, the utility model provides a kind of sealing shroud that connects special-shaped cable, the extension that sealing cover is isolated from each other by setting, and outside extension, the joint of special-shaped cable is connected, the sealability that has promoted special-shaped cable joint, has improved insulation property.
To achieve these goals, the utility model provides a kind of sealing shroud that connects special-shaped cable, and for connecting round cable and flat cable, the sealing shroud of this connection abnormity cable comprises body and extension, a part for body is hollow, and the part of hollow is hollow bulb; Another part of body is solid, and this solid part is wire separation unit, wherein in wire separation unit along being equipped with three holes insulated from each other on body length direction.
As further optimization of the present utility model, the extension of sealing shroud is three hollow circular cylinders that are isolated from each other that form along three holes in wire separation unit to body extension.
As further optimization of the present utility model, the length of hollow bulb accounts for 1/4th to 2/3rds of cover body length.
As further optimization of the present utility model, body is cylindrical.
As further optimization of the present utility model, the medial surface of body hollow bulb is the conical surface.
In technique scheme, connect the sealing shroud of special-shaped cable, because being provided with the extension being isolated from each other, outside extension, the joint of special-shaped cable is connected, promoted the sealability of special-shaped cable joint, improved insulation property.
Brief description of the drawings

Fig. 2 is the left view of sealing shroud in the utility model.
Embodiment
Below, by exemplary execution mode, the utility model is specifically described.But should be appreciated that element, structure and the feature in an execution mode also can be attached in other execution modes valuably in the situation that further not narrating.
The sealing shroud of the connection abnormity cable in the utility model is used for connecting round cable and flat cable; wherein the round cable in the utility model refers to that the outer protection cover that comprises three wires is for circular, and three wires arrangement mode in circular outer protection cover is rounded projections arranged.In addition, in the utility model, the length of indication is taking the front view of sealing shroud in Fig. 1 as with reference to defining, and in Fig. 1, is laterally said length direction in the utility model.
Referring to Fig. 1 and Fig. 2, be respectively front view and the left view of sealing shroud in the utility model.As shown in the figure, the sealing shroud that this kind connects special-shaped cable comprises body 1 and extension 2, and body 1 is cylindrical, and body 1 part is hollow, and the part of hollow is hollow bulb 11, and the medial surface of hollow bulb 11 is the conical surface; Another part is solid, and this solid part is wire separation unit 12, and wherein wire separation unit 12 is along being equipped with three holes on body 1 length direction, insulated from each other between three holes, and a wire can be inserted in each hole, and these three holes can separate three wires.An above-mentioned preferably embodiment is that the length of hollow bulb 11 accounts for 1/4th to 2/3rds of body 1 length.
With further reference to Fig. 1 and Fig. 2, three hollow circular cylinders that are isolated from each other of the extension 2 of sealing cover for forming to body 1 extension along three holes in above-mentioned wire separation unit 12.
Above-mentioned body 1 and extension 2 all adopt insulating material to make, to increase insulation property.
Concrete, in the utility model, connect the sealing shroud of special-shaped cable in use, first three wires in round cable are cut out out, and three conductor lengths that make to expose round cable are not less than the total length of extension 2 and wire separation unit 12, then round cable is extend into the hollow bulb 11 in body 1, three wires in round cable are deep in three holes in wire separation unit 12 successively, until stretch out extension 2, and then three wires that three wires in flat cable are stretched out with extension 2 are successively connected, so just make the joint between round cable and flat cable separate each other, promote the sealability of heteromorphic connector, insulation property are improved.
