Description
Technical field
The utility model is related to coal bed gas well production technique field, and in particular to coal bed gas well fishing device.
Background technology
During the water pumping gas production of coal bed gas well, because pressure change is very big in coal seam, especially in net horizontal section, easily
There is collapsing for the borehole wall, therefore, usually transferring nonmetallic screen casing in net horizontal section, i.e., a kind of surrounding of polythene material is gathered
The pipe fitting of sieve aperture, for supporting coal seam, but due in decentralization process, nonmetallic screen casing usually comes off in well halfway, shadow
The normal operation of coal bed gas well is rung, accordingly, it would be desirable to special fishing tool carries out salvaging well.
At present, being directed in coal bed gas well often has the situation of junk, and conventional fishing tool is slip-type sliding block trip spear, it
It is made up of shaft, rail plate, slips and closing piece, rail plate is located at the side of shaft, and closer to the bottom direction of shaft,
Rail plate is bigger with the distance of shaft central shaft, and slips and closing piece are arranged on rail plate, and slips can be along slip
Slide, closing piece is used to limit slips, is allowed to not skid off rail plate.The fishing tool is generally used for rigid tubular object
Salvage, junk inner chamber will be first entered under it, slips can glide because of gravity itself along inclined rail plate, with the downslide of slips, card
Watt to shaft center distance increase, slips is withstood junk inwall, afterwards, above carry slip-type sliding block trip spear, using slips with
Fishing junk is gone out well by the frictional force between junk inwall.
Prior art exist problem be：Be not suitable for salvaging resilient flexible pipe, and complex structure, be not easy to what is salvaged
Shortcoming.
Utility model content
The purpose of this utility model is the defect and deficiency for prior art, there is provided a kind of simple structure, design are closed
Reason, coal bed gas well fishing device easy to use.
To achieve the above object, the technical solution adopted in the utility model is：It comprising cover plate, reducing motor, wire spool,
Steel wire rope, through hole, support, sliding block, slide rail, suspension rod, fishing rod, recovery hook, controlling switch；Deceleration is provided with described cover plate
Motor, cover plate is provided centrally with through hole, reducing motor and wire spool drive connection, and steel wire rope, cover plate are provided with wire spool
Lower end be connected with support, support is connected with sliding block by slide rail, and the upper end of sliding block is fixedly connected with steel wire rope, the lower end of sliding block
It is connected with suspension rod, suspension rod is fixedly connected with fishing rod, some recovery hooks is provided with fishing rod；Control is provided with described cover plate
System switch, controlling switch passes through connection with reducing motor.
Preferably, described cover plate is shaped as rectangle.
Preferably, described recovery hook is convex structure, bill sets up.
Preferably, the lower end of described fishing rod is cone structure.
When the utility model is operated, fishing rod stretches into gas well, and cover plate is covered on well head, and the cover plate of rectangular shape is easy to see
Following salvaging state is examined, sliding block by itself Gravitational sliding with fishing rod, be easy to catch on screen casing side wall, starts control by recovery hook
Switch, fishing rod rises, and completes the salvaging of screen casing.
After said structure, what the utility model was produced has the beneficial effect that：Coal bed gas well described in the utility model is beaten
Device is dragged for, is adapted to salvage resilient flexible pipe, it is easy to salvage, simple to operate, laborsaving, the utility model has simple structure, sets
Put rationally, low manufacture cost the advantages of.
