Description
Technical field
The utility model relates to a kind of oilfield oil well underground fishing tool, specifically a kind of hydraulic pressure underground fishing tool of tackling all problems at once.Solve the salvaging problem of the little junk in down-hole.
Background technology
In the job execution process, the thing that the little junk in down-hole occurs happens occasionally, and the junk of the various shapes such as metal, nonmetallic, soft, hard is arranged.In case occur and will in time remove, otherwise can affect normal operation speed, even job execution can't be carried out, salvage this little junk and often can use the salvaging junk of tackling all problems at once, played good effect.But for junks such as sand faces, irregular, horizontal well, tackling all problems at once difficult, the fishing junk difficult problem of not coming up to occur closing up.
Summary of the invention
The purpose of this utility model provides a kind of hydraulic pressure underground fishing tool of tackling all problems at once, and overcomes the defective that above-mentioned prior art exists.
The technical solution of the utility model is achieved in the following ways:
The utility model comprises urceolus, tackles all problems at once, sealing ring, ball sealer, draining hole, it is characterized in that: urceolus is made as cylindrical, upper diameter is little, lower diameter is large, top be provided with the oil pipe box thread top connection, be provided with the draining hole on the top of reducing step, the interior Zhou Shuxiang in the bottom is provided with the slide groove of tackling all problems at once, and week is provided with the arc contraction mouth of necking down in the end of bottom; Tackling all problems at once, it is cylindrical to be made as, upper diameter is little, lower diameter is large, and upper periphery is provided with sealing ring, cooperates with the movable sealing of urceolus top, the upper end is provided with conical sealing seat, seal receptacle is provided with ball sealer, and the upper periphery of bottom vertically is provided with the slide rail of projection, and the slide groove set with the urceolus bottom cooperates, the bottom of bottom evenly is provided with the bailer grab of hook in the band, is provided with aperture slots between the bailer grab.
Compared with the prior art the utility model has can salvage the little junk in down-hole, salvages accurately firmly advantage, salvages the efficient height, for the fishing tool of salvaging the little junk in down-hole has enlarged range of application.
Description of drawings
Accompanying drawing-structural representation of the present utility model,
1-top connection among the figure, the 2-urceolus, 3-tackles all problems at once, 4-contraction mouth, 5-sealing ring, 6-ball sealer, 7-draining hole.
The specific embodiment
For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with Figure of description:
The utility model comprises urceolus 2, tackle all problems at once 3, sealing ring 5, ball sealer 6, draining hole 7, urceolus 2 it be made as cylindrical, upper diameter is little, lower diameter is large, top be provided with the oil pipe box thread top connection 1, be provided with draining hole 7 on the top of reducing step, the interior Zhou Shuxiang in the bottom is provided with the slide groove of tackling all problems at once, and week is provided with the arc contraction mouth 4 of necking down in the end of bottom; Tackle all problems at once 3 be made as cylindrical, upper diameter is little, lower diameter is large, and upper periphery is provided with sealing ring 5, cooperates with urceolus 2 top movable sealings, the upper end is provided with conical sealing seat, seal receptacle is provided with ball sealer 6, and the upper periphery of bottom vertically is provided with the slide rail of projection, and the slide groove set with the urceolus bottom cooperates, the bottom of bottom evenly is provided with the bailer grab of hook in the band, is provided with aperture slots between the bailer grab.
When using the utility model, connect on fishing string, in the time of on falling top of fish, clean first outer and inner outer foul of top of fish week, after cleaning up, drop into ball sealer 6 from well head, ball sealer 6 drops on the cone seal ball seat on 3 tops of tackling all problems at once, well head is suppressed with cementing truck, under the effect of hydraulic pressure, under the sealing of sealing ring 5, hydraulic pressure all acts on 3 the top of tackling all problems at once, under push away and tackle all problems at once 3,3 straight lines of tackling all problems at once under the cooperation of track and slideway groove of tackling all problems at once are descending, and the bailer grab of 3 bottoms of tackling all problems at once stretches out the contraction mouth 4 of urceolus 2 and catches little junk, because the effect of contraction mouth 4 clenches little junk, when the position of the super relief hole 7 in the position of ball sealer 6, hydraulic pressure is released, and bailer grab stops descending, on carry fishing string, little junk is mentioned ground, salvage the work of little junk and finish.
