Fig. 1 is the structural representation of the sucker-rod fishing tool provided according to the utility model one embodiment;
Fig. 2 is the structural representation of shackle in the sucker-rod fishing tool shown in Fig. 1.
Drawing reference numeral illustrates:
1-shank; 11-joint; 12-hydrophthalmia; 13-gland; 2-shackle; 21-side direction is cut sth. askew scarce face, 3-grasping part.
Detailed description of the invention
In order to have clearer understanding to the technical solution of the utility model, object and effect, existing accompanying drawings detailed description of the invention of the present utility model.
It should be noted that, in FIG, in order to structure and the position of joint and hydrophthalmia clearly can be shown, structural representation is partly cutd open in shank employing and illustrates.
As shown in Figure 1, the sucker-rod fishing tool that the utility model provides comprises: shank 1 and shackle 2, and wherein, the upper end of shank 1 is provided with top connection 11, and joint 11 can be connected with being connected tubing string, the side of shackle 2 is opened wide, and the cross sectional area of shackle 2 from top to bottom reduces gradually, what shackle 2 tilted is set on shank 1, the lower end of shackle 2 is fixedly connected with shank 1, the grasping part 3 for clamping sucker rod reduced gradually is formed from top to bottom between shackle 2 and shank 1, when sucker rod salvaged by needs, by joint 11 be connected tubing string and be connected, connection tubing string is transferred in rotation makes sucker-rod fishing tool rotation move down, because the grasping part 3 be positioned near shackle 2 open end is larger, so sucker-rod fishing tool is without the need to just to the top of sucker rod, sucker rod also can enter in grasping part 3, again because the side of shackle 2 is opened wide, so no matter whether sucker rod is bending all can enter grasping part 3 from opening wide place, and along with the rotation of sucker-rod fishing tool, be clamped in grasping part 3, when side enters to increase, when suspending weight increases, then illustrate that sucker rod has been clamped in grasping part 3 firmly, now, oil well is shifted out by connection tubing string is carried, tube connector cornice moves sucker-rod fishing tool and is pulled out by sucker rod.Compared with the fishing tool used with prior art, the sucker-rod fishing tool that the utility model provides has that structure is simple, easily processing, cost are low, not fragile, reusable, simple operation and other advantages, and no matter sucker rod is intact or bending, the salvaging effect of this sucker-rod fishing tool is all more remarkable, thus effectively improve operating efficiency, reduce operating cost.
As a preferred embodiment of the present utility model, as shown in Figure 2, shackle 2 to be cut sth. askew the back taper in scarce face 21 in having side direction, wherein, side direction scarce face 21 of cutting sth. askew forms the open side of shackle 2, then make shackle 2 be gradually sharp structure from top to bottom in back taper, such structure is simple, easy machine-shaping, not only cost savings the material manufacturing shackle 2 and use, thus reduction cost of production, and ensure that sucker rod inserts after grasping part 3 along with the rotation of sucker-rod fishing tool is clamped in grasping part 3 from open end.
Particularly, shank 1 adopts diameter to be that the round steel of 36mm is made, and shackle 2 is made up of high strength steel disc, and the lower end of shackle 2 is welded on shank 1.
Certainly, shackle 2 also can be bend by inverted trapezoidal steel disc the cirque structure opened wide in side.
Alternatively, as shown in Figure 1, shank 1 has through hydrophthalmia 12 from top to bottom, when the top of sucker rod have viscous crude, dirt, dirt husky etc. time, opening water pump makes clear water wash down the viscous crude, dirt, dirt sand etc. above sucker rod by hydrophthalmia 12, salvage efficiency to promote, reach the object of resuming production fast.
Alternatively, as shown in Figure 1, the lower end of shank 1 is convex cone shaped, and convex cone shaped structure can reduce resistance when shank 1 moves down, and what be convenient to shank 1 moves down salvaging sucker rod.
Alternatively, as shown in Figure 1, shank 1 is also provided with the gland 13 radially protruded, gland 13 is between top connection 11 and shackle 2, and the diameter of gland 13 is greater than the diameter of the upper surface of shackle 2, specifically, the setting of gland 13, avoid in the process moved down at shank 1, sucker rod is after open end enters grasping part 3, when also not clamping with grasping part 3 phase, the situation of the relative sucker-rod fishing tool of sucker rod moving grasping part 3 of leaping up out occurs, the degree of freedom that the relative sucker-rod fishing tool of sucker rod moves is limited by gland, make sucker rod can only along with the rotation of sucker-rod fishing tool, be clamped in grasping part 3, thus improve the operating efficiency of sucker-rod fishing tool, and then make sucker-rod fishing tool have good salvaging effect.
Further, in order to avoid when sucker rod does not enter grasping part 3, sucker rod is scurried out from the gap between sleeve pipe and gland 13, cause needing again to find sucker rod position, cause and salvage the generation of inefficient situation, the diameter of sleeve pipe of design sucker rod outside and the diameter difference of gland 13 are less than the diameter of sucker rod, like this, by the gap restriction sucker rod between sleeve pipe and gland moves degree of freedom, make sucker rod can be in same position in sleeve substantially all the time, thus make the fishing operation of sucker-rod fishing tool simpler, and then ensure that the salvaging efficiency of sucker-rod fishing tool.
Connection with figures illustrates the specific works process of the sucker-rod fishing tool that the utility model provides below:
After the particular location examining top of fish (sucker rod), select the sucker-rod fishing tool matched with this top of fish (sucker rod) diameter, namely the sucker-rod fishing tool with the grasping part 3 that can clamp this sucker rod is selected, after choosing sucker-rod fishing tool, as shown in Figure 1, by the joint 11 of this sucker-rod fishing tool be connected tubing string be connected after under put into well, in the process of going into the well, if do not arrive top of fish (sucker rod) place just to meet obstructions, carry then and connect tubing string 1m, then turn on pump circulation is transferred, clear water washes down the viscous crude of top of fish (sucker rod) top by the hydrophthalmia that shank is arranged, dirt, sand setting etc., treat the viscous crude of top of fish (sucker rod) top, dirt, after sand setting washes down, continue to transfer and connect tubing string until sucker-rod fishing tool is to top of fish (sucker rod) position, after examining, on carry and connect tubing string 1m-2m, rotation is transferred, if top of fish (sucker rod) is not clamped in grasping part 3, namely in not dragging for, then again on carry and connect tubing string 1m-2m, rotation is transferred, so repeatedly for several times, until side enters to increase, suspending weight increases, namely top of fish (sucker rod) is clamped in grasping part 3 firmly, sucker-rod fishing tool has dragged for and has obtained top of fish (sucker rod), now, on carry connect tubing string top of fish (sucker rod) can be pulled out.
In sum, the sucker-rod fishing tool that the utility model provides has that structure is simple, easily processing, cost are low, not fragile, reusable, simple operation and other advantages, and no matter sucker rod is intact or bending, the salvaging effect of this sucker-rod fishing tool is all more remarkable, thus effectively improve operating efficiency, reduce operating cost; In addition, the sucker-rod fishing tool that the utility model provides has hydrophthalmia, and clear water washes down the viscous crude, dirt, dirt sand etc. above sucker rod by hydrophthalmia, to promote salvaging efficiency, reaches the object of resuming production fast.
The foregoing is only the schematic detailed description of the invention of the utility model, and be not used to limit scope of the present utility model.Any those of ordinary skill in the art, equivalent variations done under the prerequisite not departing from design of the present utility model and principle and amendment, all should belong to the scope of the utility model protection.
