Abstract
The multi-thread cable protection device in a kind of down-hole, comprises housing, active connection, semicircle clip, rubber cushion blocks, draw-in groove, pin jack.Described housing is a strip arcuate structure, and its both ends are installed and are connected with two semicircle clips, in housing, semicircle clip, rubber cushion blocks are installed, and rubber cushion blocks is provided with draw-in groove.The utlity model has multi-thread cable protection device structure; use, fitting operation is fast and simple, have polylith rubber protection cable use safety, can auto-strengthening tubing string; avoid protector to produce displacement, use occasion wide, be not only applied to land down-hole, be more suitable for applying in offshore well.
Description
Technical field
The utility model relates to oil well cable protector, particularly the multi-thread cable protection device in a kind of down-hole.
Background technology
The cable protection device that offshore production well completion is used at present; its structure is simple single groove shape; the cable protection device of this structure is that offshore production well completion has been brought into play effect; but it exists following shortcoming or deficiency simultaneously: 1. hold cable few; multipotency holds 1 cable and liquid controling pipe line; thereby having restricted its use value, the instrument that has limited oil well completion uses.2. particularly the offshore field overwhelming majority is directional well, and completion tubular column is that to paste casing wall one side descending in pit shaft, very easily causes cable and controls the damage of pipeline, and existing cable protection device has not reached requirement.3. when use procedure plays lower tubular column, easily cause protector displacement damage cable insulation, thereby cause the faults such as electric pump well stopping production.4. in completion tubular column, the outfit of the device such as electric pump working condition acquiring instrument, viscosity reduction de-plugging control valve use is restricted.5. because the use of existing cable protection device is limited, the outfit of producing well fine-grained management, electric pump working condition acquiring instrument, viscosity reduction de-plugging control valve etc. is used and is also restricted, thus directly affect instrument, the development of technique and the trouble-free operation of production.
Summary of the invention
The purpose of this utility model is to provide the multi-thread cable protection device in a kind of improved down-hole, adopts the combining structure of anti-corrosion alloy shell, bending metals shell fragment and rubber fritter, effectively overcomes or avoids the shortcoming or the deficiency that in above-mentioned prior art, exist.
The multi-thread cable protection device in down-hole described in the utility model, comprises housing, active connection, semicircle clip, rubber cushion blocks, draw-in groove, pin jack.Described housing is a strip arcuate structure, and its both ends are installed and are connected with two semicircle clips, in housing, semicircle clip, rubber cushion blocks are installed, and rubber cushion blocks is provided with draw-in groove.
Wherein, the strip arcuate structure of described housing is just in time consistent with tubing coupling and upper and lower profile thereof.The two ends up and down of described semicircle clip, are installed on metal clips at least a slice consistent with semicircle clip shape.Described active connection is chain connection.Draw-in groove on described rubber cushion blocks, is at least provided with one.
The utility model compared with prior art tool has the following advantages:
1, multi-thread cable protection device structure advanced person, uses, fitting operation is fast and simple;
2, be provided with many and control pipelines and cable passage, can solve preferably in producing well tubing string cable number and use limitedly, particularly in offshore production well casing post, cable number uses limited problem;
3, owing to there being the protection of polylith rubber can conscientiously protect the use safety of cable.
4, owing to adopting upper and lower two bending metals shell fragments, in use can auto-strengthening tubing string, avoid protector generation displacement in lower tubular column process.
5, use occasion is wide, is not only applied to land down-hole, is more suitable for applying in offshore well.
Brief description of the drawings
Fig. 1 is a kind of example structure schematic diagram of the present utility model;
Fig. 2 is by the plan structure schematic diagram shown in Fig. 1.
Detailed description of the invention
Consult Fig. 1-Fig. 2, the multi-thread cable protection device in a kind of down-hole, comprises housing 1, active connection 2, semicircle clip 3, rubber cushion blocks 4, draw-in groove 5, pin jack 6.Housing 1 is a strip arcuate structure, and its both ends are installed and are connected with two semicircle clips 3, in housing 1, semicircle clip 3, rubber cushion blocks 4 are installed, and rubber cushion blocks 4 is provided with draw-in groove 5.
The strip arcuate structure of housing 1 is just in time consistent with tubing coupling and upper and lower profile thereof.The two ends up and down of semicircle clip 3, are installed on metal clips at least a slice consistent with semicircle clip 3 shapes, are expressed as 6 in figure.Active connection 2 is chain connection.Draw-in groove 5 on rubber cushion blocks 4, is at least provided with one, is expressed as 4 in figure.
When operation is gone into the well, housing 1 is close to tubing string surface, and cable is included in rubber protector completely, and semicircle clip 3 is fixed on oil-pipe external wall by pin jack 6 and pin, effectively protects cable.
