Abstract

The utility model relates to a kind of oil well repairing operation fishing tool, particularly the spiral sucker-rod fishing tool of one.The female coupling tap upper end of this device is provided with top connection, and female coupling tap lower end is provided with guide shoe, is designed with alloy block inside guide shoe, and female coupling tap inwall is designed to the screwed conical surface, and the outer hook of loose-leaf is connected in female coupling tap upper inside wall, and the outer hook lower end of loose-leaf is provided with milling shoe.The irregular top of fish that the utility model achieves sucker rod junk and the coiling of many sucker rods of Underground Spiral shape are formed once is salvaged successfully, decrease the salvaging number of times of the sucker rod junk of Underground Spiral shape, increase work efficiency, avoid dropping in trip-out process, reduce workover treatment cost.The irregular top of fish overcoming existing spiral sucker rod junk and many sucker rods coiling formation implements substep salvaging, and long construction period, success rate is low, easily falls into the deficiency in well in trip-out process.

Description

A kind of spiral sucker-rod fishing tool
Technical field:
The utility model relates to a kind of oil well repairing operation fishing tool, particularly the spiral sucker-rod fishing tool of one.
Background technology:
The well that sucker rod is salvaged in overhaul in recent years increases year by year, often will process the irregular top of fish of some spiral sucker rod junks and many sucker rods coiling formation.Special fishing tool and technology has been had at present for the sucker rod that top of fish is intact or upright, and shaping fishing tool is not also had for the irregular top of fish that spiral sucker rod junk and the coiling of many sucker rods are formed, generally well inside spin sucker rod is compressed, make it bending, then hook with dead hook, or adopt milling cone milling eye, then hook with dead hook.Because the sucker rod itself of coiling or spiral has elasticity, milling eye poor effect, but in the process of long-time milling eye, not only easily damage sleeve pipe, and easily the milling of spirality sucker rod is become some sections, in the process playing hook, easily cause the sucker rod on hook again to fall well, in operation process, more easily make salvaging complicated, make fishing success ratio very low, for later salvaging causes very large difficulty, when dealing with improperly, the complicated or oil well of overhaul can be caused to scrap.
Utility model content:
The technical problems to be solved in the utility model is to provide a kind of spiral sucker-rod fishing tool, the irregular top of fish that the arrangement achieves sucker rod junk and the coiling of many sucker rods of Underground Spiral shape are formed once is salvaged successfully, decrease the salvaging number of times of the sucker rod junk of Underground Spiral shape, increase work efficiency, avoid dropping in trip-out process, reduce workover treatment cost.The irregular top of fish overcoming existing spiral sucker rod junk and many sucker rods coiling formation implements substep salvaging, and long construction period, success rate is low, easily falls into the deficiency in well in trip-out process.
Technical solution adopted in the utility model is: a kind of spiral sucker-rod fishing tool, comprises female coupling tap; Female coupling tap upper end is provided with top connection, and female coupling tap lower end is provided with guide shoe, is designed with alloy block inside guide shoe, and female coupling tap inwall is designed to the screwed conical surface, and the outer hook of loose-leaf is connected in female coupling tap upper inside wall, and the outer hook lower end of loose-leaf is provided with milling shoe.
The beneficial effects of the utility model are: the irregular top of fish that the utility model achieves sucker rod junk and the coiling of many sucker rods of Underground Spiral shape are formed once is salvaged successfully, decrease the salvaging number of times of the sucker rod junk of Underground Spiral shape, increase work efficiency, avoid dropping in trip-out process, reduce workover treatment cost.
Accompanying drawing illustrates:
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
As shown in Figure 1, a kind of spiral sucker-rod fishing tool, comprises female coupling tap 1, female coupling tap 1 upper end is provided with top connection 2, female coupling tap 1 lower end is provided with guide shoe 3, alloy block 6 is designed with inside guide shoe 3, female coupling tap 1 inwall is designed to the screwed conical surface, female coupling tap 1 is conducive in spiral shaft-like junk income bobbin, the outer hook 4 of loose-leaf is connected in female coupling tap 1 upper inside wall, outer hook 4 lower end of loose-leaf is provided with milling shoe 5, milling eye is carried out at milling shoe 5 pairs of junk centers, pressurization, salvage, the inwall of female coupling tap 1 has high-strength screw thread simultaneously, junk is tightened up, make junk dish tightly on the outer hook 4 of loose-leaf, complete salvaging, and in the process pulled out of hole, due to hook, bobbin and junk do not produce relative displacement, can not drop.
After the utility model is gone into the well, after encountering top of fish, rotary tools, alloy block 6 inside guide shoe 3 can repair top of fish, by in the female coupling tap 1 of larger top of fish income instrument, milling shoe 5 carries out milling eye simultaneously, makes the outer hook 4 of loose-leaf enter in spiral sucker rod junk smoothly, female coupling tap 1 pair of junk tightens up simultaneously, the outer hook 4 of junk, loose-leaf and female coupling tap 1 are combined together, prevents in trip-out process and drop, ensure that salvaging one-time success rate, improve operating efficiency, guarantee that oil-water well reproduces fast.
Be understandable that, above about specific descriptions of the present utility model, the technical scheme described by the utility model embodiment is only not limited to for illustration of the utility model, those of ordinary skill in the art is to be understood that, still can modify to the utility model or equivalent replacement, to reach identical technique effect; Needs are used, all within protection domain of the present utility model as long as meet.
