Description
Technical field
The utility model relates to a kind of oil well operation equipment, particularly a kind of oil-water well maintenance fishing device.
Background technology
Oil well recovers the oil in production long-term, often occur swab line beat twist off de-, add oil pipe or fill with that plumbous tubing nipple comes off, the phenomenon such as the fatigue damage of swab annex and swab rubber come off, junk is cumulative, in addition formation sand production, sleeve scaling etc., make pit shaft situation complicated, cause oil well to be in and stop well state.
China Patent Publication No. is: CN 201738858 U, patent name is: " sucker rod socket ", primarily of top connection, urceolus, spring, stay pipe, slip segment and guide shoe composition, top connection is that cylindrical has centre bore, top connection wall has well liquid circulation port, and have external screw thread at the two ends up and down of top connection, upper external screw thread can connect fishing string, it is characterized in that: be threaded in top connection lower end urceolus, be threaded in the lower end of urceolus guide shoe; Compress Spring, stay pipe and slip segment is fixed with from top to bottom in top connection bottom and guide shoe top in urceolus; Slip segment is cone shape, and slip segment outer wall is conical, and slip segment inwall is conical, and the inwall of slip segment has transversely arranged slip insert, and the larger diameter end of slip segment is downward, and the cone that slip segment is made up of two semicircle cones.
This marine salvage equipment complex structure, intricate operation, salvaging efficiency is low, affects normal oil well fishing, when salvaging lifting operation, easily produces junk and falls, need secondary to salvage, waste time and energy, affect normal oil mining.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provides a kind of oil-water well to keep in repair fishing device.
Its technical scheme is: comprise top connection, urceolus gland, guide shoe, spacer, grabber, expansion link, lifting rod, lift unit, the bottom of top connection is threaded connection urceolus gland, the end of urceolus gland connects guide shoe, the central axis of top connection is provided with expansion link, the inside of expansion link is provided with lifting rod, the inside of described urceolus gland is provided with lift unit, the top connection expansion link of described lift unit, the end of lift unit connects grabber, described grabber connects lifting rod, described grabber comprises cone frame, capture hook, spring, guide peg, the top of cone frame connects lifting rod, the bottom of cone frame connects guide peg, the inside of described centrum frame connects crawl hook by spring.
Above-mentioned lift unit comprises carrying and draws ring, permanent magnet, and carry the upper end connection expansion link drawing ring, carry the end fixed permanent magnet drawing ring, the center of permanent magnet is provided with through hole.
The beneficial effects of the utility model are: have the advantages such as structure is simple, easy to operate, dependable performance, small in volume, the small falling objects such as the drill point fallen in well, palm, gear wheel, bearing, slips body, slip insert, tong tooth and other instruments are captured and picks up, thus effectively salvage small falling object, purification shaft bottom, salvage crawl efficiency high, improve the operating efficiency that oil well is salvaged, permanent magnet attraction is passed through in lifting process, prevent junk secondary to fall, ensure that salvaging effect.
