Abstract
The utility model discloses a kind of special rubber-cylinder fishing device, it comprises main body, centralizer and tapered drill bit, and several centralizers are sleeved on body top, and described tapered drill bit is arranged on the lower end of main body.This fisher realizes penetrating and fishing the packing element being in various states, can manufacture on packing element very smoothly and salvage hole, and be hooked by packing element controller, prevent the salvaged packing element come up from again dropping in well, fishing success ratio improves greatly, improves well workover efficiency.
Description
Technical field
The utility model relates to oil well kit technical field, particularly the special rubber-cylinder fishing device of one.
Background technology
When compression type glue barrel or expanding packing element drop to after in pit shaft from instrument, some damages, and its position situation is also more complicated, general packing element fishing tool is adopted not only to salvage incessantly, salvage exactly, can again drop in pit shaft again in lift pipe string process, so be difficult to salvage; Especially expanding packing element, when packing element malposition, there is multiple layers of high strength line its inside, and common fishing tool, in salvaging process, is difficult to salvage from packing element itself through after line.
Summary of the invention
For solving the problem, the purpose of this utility model is to provide a kind of special rubber-cylinder fishing device, this fisher realizes penetrating and fishing the packing element being in various states, can manufacture on packing element very smoothly and salvage hole, and hooked by packing element controller, prevent the salvaged packing element come up from again dropping in well, fishing success ratio improves greatly, improves well workover efficiency.
For achieving the above object, a kind of special rubber-cylinder fishing device disclosed in the utility model, it comprises main body, centralizer and tapered drill bit, and several centralizers are sleeved on body top, and described tapered drill bit is arranged on the lower end of main body.
Further, spacer ring is provided with between centralizer described in several.
Further, described tapered drill bit comprises taper seat, taper seat is provided with the cutting edge of screw type.
Further, between described centralizer and described tapered drill bit, described main body upper outer surface is provided with packing element controller, packing element controller is the multiple barbs be arranged in main body.
Further, the cross section of described cutting edge is triangle.
This instrument is connected to fishing string foot, after fisher runs into packing element, while pressing down tubing string, rotate forward tubing string, under the effect of centralizer, tapered drill bit is in cannula center position, and the packing element being in this position will be drilled, and continues rotary drilling, packing element can be pushed through on packing element controller, if now upper lifting pipe post, packing element will be hung in cannot be descending on controller, so packing element is salvaged firmly.If the packing element of going into the well is a lot, can many rotary drillings, once can salvage multiple packing element.
Accompanying drawing explanation
The structural representation of a kind of packing element special-purpose fisher that Fig. 1 provides for the utility model embodiment;
In figure: 1-main body; 2-centralizer; 3-spacer ring; 4-packing element controller; The tapered drill bit of 5-; 5.1-screw type cutting edge.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, a kind of special rubber-cylinder fishing device, it comprises main body 1, centralizer 2 and tapered drill bit 5, two centralizers 2 and is sleeved on main body 1 top, and tapered drill bit 5 is arranged on the lower end of main body 1.Spacer ring 3 is provided with between centralizer 2.Tapered drill bit 5 comprises taper seat, taper seat is provided with the cutting edge 5.1 of screw type.The cross section of cutting edge is triangle.
Between centralizer 2 and tapered drill bit 5, main body 1 upper outer surface is provided with packing element controller 4, packing element controller 4 is for being arranged on the multiple barbs in main body.
The utility model structure is simple, easy to use, can the multiple packing element of disposable salvaging, and can not come off halfway, substantially increases salvaging efficiency.
Below only describe several preferred embodiments of the application by reference to the accompanying drawings, but the application is not limited thereto, every those of ordinary skill in the art are under the spirit not departing from the application, and any improvement made and/or distortion, all belong to the protection domain of the application.
