Abstract
The invention discloses an oil well fisher. The oil well fisher comprises a supporting column, a plurality of rectangular holes are formed in the side wall of the supporting column, a plurality of limiting holes connected with the rectangular holes are formed in the bottom of the supporting column, a tapered supporting rod is fixed into a hollow cavity of the supporting column, a plurality of claws are connected to the side wall of the supporting rod through hinges, an electromagnet is connected with an external power source through a wire, and magnets matched with the electromagnet are installed on the sides, close to the supporting rod, of the claws. The supporting column is slowly placed into an oil well, the power source is switched on, the electromagnet and the magnets on the claws interact, in other word, the electromagnet attracts the magnets so that the upper ends of the claws retract inwards around a hinged point, the other ends of the claws expand outwards around a hinged point, internal space in a cylindrical clamping space formed by the claws is increased, and it is guaranteed that the claws can clean sundries such as chippings, steel ropes and cable ropes in the whole oil well.
Description
Technical field
The present invention relates to oil field, specifically refer to a kind of oil well fisher.
Background technology
In oil well operation process; the junk that some affect operation and oil exploitation usually can be fallen in oil well; be generally the elongated and object that body is soft such as some wire rope, cable, steel wire for logging, these junks need pull out in oil well in time, in order to avoid soil-well jam or damage equipment.Drag for rope instrument inner for oil well rope form junk to be pulled out though present, but it is low not only to salvage efficiency, and salvages thorough not, many tiny, things not easily salvaged that drops that length is shorter, cause the salvaging cycle also to extend.
Summary of the invention
The object of the present invention is to provide a kind of oil well fisher, the rope instrument that drags in the past of solving salvage efficiency low, salvage halfway problem.
Object of the present invention is achieved through the following technical solutions:
A kind of oil well fisher, comprise the support column of inner hollow, the sidewall of described support column has multiple rectangular opening, the bottom of support column has multiple spacing hole interconnective with rectangular opening, the hollow cavity internal fixtion of support column has the support bar of taper, is connected with multiple claw at the sidewall upper hinge of described support bar; Also comprise buffer structure and the electromagnet being fixed on supporting bar top, electromagnet is connected with external power source by wire, and the magnet matched with electromagnet is installed on the side of support bar at claw, described buffer structure comprises the adjustable ring being fixed on support bar lower end, the outer circle wall of adjustable ring is provided with the arc rubber pad that claw is corresponding, and is fixed with at the two ends of arc rubber pad the elastic sheet metal that cross section is 1/4th unit circles respectively.When the present invention works, rectangular opening and spacing hole form the L shape activity interval of claw on support bar, support column is slowly put into oil well, start power supply simultaneously, magnet on electromagnet and claw is interacted, namely electromagnet produces magnet and attracts the upper end of claw is inwardly bounced back around pin joint, and the other end of claw expands outwardly around pin joint, the inner space of the column grasping part that multiple claw is formed increases, namely ensure that claw can to the foreign material of the whole inside of oil well, such as crushed stone, wire rope, cable rope etc. are cleared up; When the bottom of claw is placed in shaft bottom, the electric current passed in electromagnet changes, the attraction state of electromagnet to magnet is made to become repulsion state, the upper end of claw starts away from electromagnet, its other end is then close to support column axis place place, and then the grasping part making the foreign material etc. in oil well enter multiple claw to be formed, when the ends contact of the inwall of claw and spacing hole, claw stops continuing to move, and prevents multiple claw from excessively moving each other and causing impaired;
Wherein, adjustable ring is fixed on the lower end of support bar, its outer circle wall is fixed with arc rubber pad, elastic sheet metal is fixed with at the two ends of arc rubber pad, when after the clamping that claw completes foreign material, the inwall priority of claw and elastic sheet metal, arc rubber pad contacts, by the buffering of elastic sheet metal to claw movement tendency, connection between claw and support bar is become flexibly connect, avoid serious collision occurs between claw and support bar, avoid the bottom of multiple claw mutually clash into and cause the foreign material in claw to fall because rocking simultaneously, effect is salvaged in further raising.
The inner wall at end of described claw is fixed with latch.For strengthening the salvaging effect of claw to foreign material further, claw being provided with latch, preventing foreign material from dropping in salvaging uphill process.
Multiple described claw ringwise and array distribution on support bar.Multiple claw annular array is hinged on support bar, makes multiple claw form a cone shape grasping part, to ensure that claw is cleared up completely to the foreign material in oil well.
Also comprise connector, described connector is fixed on the top of support column and coordinates with the lifting gear of outside.Connector is used for being connected with the lifting gear of outside, and this lifting gear can be steel cable or draw bar, is shifted out together in oil well by related for salvaging structure foreign material by steel cable or the lifting of draw bar.
The present invention compared with prior art, has following advantage and beneficial effect:
1, support column is slowly put into oil well by the present invention, start power supply simultaneously, magnet on electromagnet and claw is interacted, namely electromagnet produces magnet and attracts the upper end of claw is inwardly bounced back around pin joint, and the other end of claw expands outwardly around pin joint, the inner space of the column grasping part that multiple claw is formed increases, and namely ensure that claw can to the foreign material of the whole inside of oil well, such as crushed stone, wire rope, cable rope etc. are cleared up;
2, the present invention strengthens the salvaging effect of claw to foreign material further, and claw is provided with latch, prevents foreign material from dropping in salvaging uphill process;
3, the multiple claw annular array of the present invention is hinged on support bar, makes multiple claw form a cone shape grasping part, to ensure that claw is cleared up completely to the foreign material in oil well.
