Specific implementation mode
The more guide shoe die nipple fishing devices of the big size hole of the utility model are described in detail below in conjunction with the accompanying drawings.
Fig. 1 is the structural schematic diagram of the more guide shoe die nipple fishing devices of the utility model big size hole, and it illustrates this realities With a kind of preferred embodiment of the novel more guide shoe die nipple fishing devices of big size hole.
As shown in Figure 1, a kind of more guide shoe die nipple fishing devices of big size hole comprising connector 1, outer barrel 2,3 and of die nipple Guide shoe structure.
Preferably, outer barrel 2 includes enlarged diameter section 21 and reduced diameter section 22.Reduced diameter section 22 passes through a hollow cone mesa-shaped Changeover portion 23 is set to the top of enlarged diameter section 21.
Connector 1 is set to the top of outer barrel 2 in such a way that outer barrel 2 is inserted into its lower end.Preferably, the internal diameter of reduced diameter section 22 Match with the outer diameter of connector 1, the lower end of connector 1 passes through reduced diameter section 22, is connected with reduced diameter section 22 in a manner of grafting.
Further, connector 1 is connected by way of welding or being threadedly coupled with outer barrel 2 so that connector 1 is fixed on outer The top of cylinder 2.
In a state of use, the upper end of connector 1 is connected to drilling rod tubing string.Preferably, the upper end of connector 1 is provided with spiral shell Line so that the mode that the upper end of connector 1 can be connected through a screw thread in a state of use is connected with drilling rod tubing string.In addition, connector 1 On connection structure (such as connection screw thread) can flexibly be selected according to the button property of tool joint connected to it.
Die nipple 3 is set in outer barrel 2 and is connected with the lower end of connector 1.Preferably, die nipple 3 is connected by welding or screw thread The mode connect is connected with the lower end of connector 1.
Guide shoe structure includes middle level guide shoe 4 and internal layer guide shoe 5.
Wherein, middle level guide shoe 4 is set to the inner wall lower of outer barrel 2, it is preferred that middle level guide shoe 4 is connected by welding or screw thread The mode connect is connected with the inner wall lower of outer barrel 2.
Wherein, internal layer guide shoe 5 is set on middle level guide shoe 4.Preferably, internal layer guide shoe 5 is by welding or being threadedly coupled Mode is connected with the inside of middle level guide shoe 4.
And the size of middle level guide shoe 4, internal layer guide shoe 5 is sequentially reduced, to guide fish tubing string to enter in outer barrel 2, Die nipple 3 is entered in the hydrophthalmia of fish tubing string;And then to carrying out thread making inside fish tubing string, to salvage fish pipe Column opens out fish tubing string.
In addition, the guide shoe size and the guide shoe number of plies of the utility model can be actually needed and be adjusted flexibly.
The more guide shoe die nipple fishing devices of big size hole of the utility model use process is as follows:
When the more guide shoe die nipple fishing devices of big size hole of the utility model carry out fishing, connector 1 is connected to On drilling rod tubing string, transferred to the fish tubing string top of fish of shaft bottom by drilling rod tubing string, outer barrel 2, middle level guide shoe 4, internal layer draw Shoes 5 work successively leads into the fish fish head of the relatively side borehole wall inside fishing device so that die nipple 3, which can enter, to be fallen In the hydrophthalmia of fish tubing string;And then open out fish tubing string to salvage fish tubing string carrying out thread making inside fish tubing string, it is real Now salvage function.
The more guide shoe die nipple fishing devices of big size hole of the utility model are sequentially reduced by the way that size is arranged in outer barrel 2 Middle level guide shoe 4 and internal layer guide shoe 5, be formed as a salvaging outer barrel with multilayer guide shoe structure, and die nipple 3 is arranged at it It is interior so that die nipple integrates with the salvaging outer barrel with multilayer guide shoe structure;In use, being transferred into well by drilling rod tubing string, lead to Cross multilayer guide shoe structure guides fish tubing string to enter inside fishing device successively, and last resort die nipple is at fish tubing string top of fish position It is opened after thread making inside hydrophthalmia and grows well casing column, and then realized and salvage function.The more guide shoe die nipples of big size hole of the utility model Fishing device can solve to solve fish tubing string when fish tubing string has big difference with borehole size and be affixed on the side borehole wall, conventional die nipple Fishing tool is difficult to the problem of salvaging fish;And the more guide shoe die nipple fishing devices of big size hole of the utility model have knot The advantages that structure is novel, processing is simple, applied widely, easy to use.
It should be noted that all features disclosed in this specification or disclosed all methods or in the process the step of, Other than mutually exclusive feature and/or step, it can combine in any way.
