Abstract

The utility model relates to a steel wire fishing device used in oil-water well, belonging to an underground steel wire fishing device. The utility model solves the disadvantages that the prior fishing device can not compress the steel wire in the well to a ball; the fishing hook can not accurately hook the steel wire; when the steel wire is hooked by the hook, the fishing device has been at a deep well position and the steel wire in the well has been compressed into a bigger ball so as to make the fishing operation more difficult and reduce the work efficiency. The utility model comprises a top wire (1), a plurality of steel reinforcing bars (2) and a fishing hook (3), wherein the four steel reinforcing bars (2) are evenly fixed on the outer diameter at the bottom of the top wire (1); each steel reinforcing bar is provided with a fixing column (5) vertical to the steel reinforcing bar (2); a steel wire compress-spring (4) is horizontally arranged on the fixing column (5); and the fishing hook (3) is arranged at the bottom of each steel reinforcing bar (2) at the bottom of the steel wire compress-spring (4). Whether the well has an inclined mouth or other reasons, the utility model can compress the fallen steel wire to a ball, and the fishing hook can accurately catch the steel wire every time to fish steel wire up with high successful fishing rate.

Description

Oil-water well steel wire fishing device

Technical field

The utility model relates to down-hole steel wire fishing device.

Background technology

At present, in the oil water well test process, instrument band steel wire occurs through regular meeting and fall into phenomenon in the well.And the existing instrument of salvaging steel wire is not a lot, and interior hook fisher and outer hook fisher are arranged.But the success rate of salvaging steel wire is not high.Existing recovery hook is when well head is crooked, and maximum outside diameter does not reach the designing requirement of 58mm, and pressure hook can't be pushed down steel wire.In the salvaging process, the interior hook fisher or the outer hook fisher that adopt, can not well play a role, often cause because fishing tool when G.I.H, can not push steel wire in the well agglomerating, cause recovery hook can't accurately catch steel wire, when easily causing recovery hook to hook steel wire, salvage instrument very dark position under the lower going-into-well, steel wire has been formed bigger steel wire group in the well, the salvage difficulty is strengthened, salvage efficient and reduce.

The utility model content

The utility model can not be agglomerating steel wire extruding in the well in order to solve existing fishing device, recovery hook can't accurately be caught steel wire, when recovery hook hooks steel wire, fishing device has entered the position of deep-well, steel wire has been formed bigger steel wire group in the well, make the problem that the salvage difficulty strengthens, efficient reduces, a kind of oil-water well steel wire fishing device is provided, the concrete technical scheme that addresses the above problem is as follows:

The utility model comprises jackscrew 1, reinforcing bar 2, recovery hook 3, reinforcing bar 2 is on four cylindricals that are fixed on jackscrew 1 bottom equably, it also includes steel wire compression spring 4, on every reinforcing bar 2, be provided with the fixed leg 5 vertical with reinforcing bar 2, steel wire compression spring 4 crosswise fixed are on fixed leg 5, and recovery hook 3 is located on the end of reinforcing bar 2 of steel wire compression spring 4 bottoms.

The utility model is no matter well head is askew and other reasons can both be agglomerating with the steel wire extruding that falls in the well, and recovery hook can accurately catch steel wire once it to be salvaged, and the success rate of salvaging is very high.Only the well steel wire that falls of 8 mouthfuls of wells adopts this device to salvage test, just saves 600,000 yuan of fishing expenses.

Description of drawings

Fig. 1 is a structural representation of the present utility model, and Fig. 2 is the syndeton schematic diagram of fixed leg 5 and steel wire compression spring 4 on the reinforcing bar 2.

The specific embodiment

The specific embodiment one: describe present embodiment in conjunction with Fig. 1.Present embodiment is made up of jackscrew 1, reinforcing bar 2, recovery hook 3 and steel wire compression spring 4, reinforcing bar 2 is on four cylindricals that are fixed on jackscrew 1 bottom equably, on every reinforcing bar 2, be provided with the fixed leg 5 vertical with reinforcing bar 2, steel wire compression spring 4 crosswise fixed are on fixed leg 5, recovery hook 3 is located on the end of every reinforcing bar in steel wire compression spring 4 bottoms 2, the top of jackscrew 1 has 1.5 meters weighted levers, and the weighted lever upper end is connected with rope socket, and rope socket is connected with wire rope.

The specific embodiment two: the maximum length of the steel wire compression spring 4 of present embodiment is 60mm.

The steel wire that falls in the oil-water well can both be pressed onto by steel wire compression spring 4, totally remove the steel wire that the handle at the end falls in the oil-water well and salvage out.

The specific embodiment three: an angle α is arranged between the recovery hook 3 of present embodiment and the reinforcing bar 2, and angle α is 15 °～30 °.

Actual test:

Connect homemade tack with 1.5 meters weighted levers and go into the well and pound rope socket place steel wire, pound repeatedly four, five times, steel wire is pounded down from rope socket.Then with the salvaging of going into the well of 1.5 meters these fishing devices of weighted lever band, before going into the well, earlier four steel wire compression spring 4 length are transferred to maximum 60mm, this fishing device under the well head, when fishing device bit by bit was pressed into 3～7 meters little with steel wire in the decline process, recovery hook 3 was just held by the little group of steel wire, can't fall, on carry fishing device, steel wire is salvaged well head, drag for rope socket at following 1 meter weighted lever band oscillator, slips fishing head and vibrate repeatedly four, five times, after the unfreezing, pull junk smoothly out.
