Abstract

The utility model provides a windowed fishing barrel for fishing a sucker rod. The windowed fishing barrel comprises a tubular fishing barrel body; a section of connecting oil pipe is fixedly arranged on the upper part of the fishing barrel body; the upper part of the connecting oil pipe is fixedly connected with a nipple; two windows are symmetrically formed in the tubular wall of the fishing barrel body; window bolts inclined upwards and toward the interior of the fishing barrel body are formed on the windows; the distance between the tops of the two opposite window bolts is smaller than the diameter of a coupling on the sucker rod. The windowed fishing barrel for fishing the sucker rod is capable of preventing large-scale crude oil pollution while fishing the sucker rod, reducing the fishing cost and saving manpower and material resources.

Description

For salvaging the window cutting dipper of sucker rod
Technical field
The utility model is the fishing tool about a kind of sucker rod, relates in particular to a kind of for salvaging the window cutting dipper of sucker rod.
Background technology
After at present the well rod in oil field breaks and, must allow outside underground work troop examine bar construction, adopt cover to put forward the method under cover, utilize the fishing tools such as fishing spear first to propose ground by lower to underground oil pipe, again the beam hanger of appearing is proposed to ground, detect the complete pipe lower beam that again descends again, whole process is very loaded down with trivial details, take time and effort, and cover carries that the lower crude oil pollution area of cover is large, to put rod tube cross action safety factor low in practice; Fisher in practice tooth sheet is frangible easily de-, and effect is bad, and it is higher to salvage cost, labor intensive material resources.
Thus, the inventor relies on experience and the practice of being engaged in for many years relevant industries, proposes a kind of for salvaging the window cutting dipper of sucker rod, to overcome the defect of prior art.
Utility model content
It is a kind of for salvaging the window cutting dipper of sucker rod that the purpose of this utility model is to provide, and to stop large-area crude oil pollution in sucker rod is salvaged, reduces and salvage cost, uses manpower and material resources sparingly.
The purpose of this utility model is achieved in that a kind of described window cutting dipper includes tubulose dipper body for salvaging the window cutting dipper of sucker rod, and dipper body top is fixed with one section of connected pipes, and this connected pipes top is fixedly connected with a pipe nipple; On the tube wall of described dipper body, being relatively provided with two windows; The window tongue that the described upper formation of windowing is tilted to towards dipper body interior; Distance between described two relative window tongue tops is less than the diameter of box cupling on sucker rod.
In a preferred embodiments of the present utility model, guide shoe shape is arranged in the bottom of described dipper body.
In a preferred embodiments of the present utility model, described in the rectangular shaped of windowing, described in the upper side edge of windowing be connected with tube wall, another three sides and tube wall cut off; Described window along upper side edge to body in top turnover form described window tongue.
In a preferred embodiments of the present utility model, described in window and be up-small and down-big trapezoidal shape, described trapezoidal upper base of windowing is connected with tube wall, another three sides and tube wall cut off; Described trapezoidal window along upper base to body in top turnover form described window tongue.
In a preferred embodiments of the present utility model, described dipper body is that 2~3.5m, external diameter are that the standard oil pipe that 88.9mm, internal diameter are 74.22mm forms by a segment length; The oil pipe that described connected pipes is 73mm by one section of diameter forms.
In a preferred embodiments of the present utility model, the distance between described two relative window tongue tops is less than 25mm.
From the above mentioned, in the time salvaging the disconnected sucker rod dropping in oil well, described window cutting dipper moves down and moves down, the top of sucker rod is introduced in dipper body, then to window cutting dipper pressurization 5~8KN, while is due to the Action of Gravity Field of salvaging system self, window cutting dipper enters down-hole smoothly, break the top of the sucker rod that falls also smoothly by two groups of positions of windowing, in the time that sucker rod passes through two relative window tongue top spacings, although two window tongues can push and deformation owing to being subject to box cupling on sucker rod, but losing after extruding force (being that box cupling passes through), two window tongues can be because self elastic recovery be to heeling condition, when whole window cutting dipper is upwards lifted, two window tongue tops just can be stuck in the box cupling lower end of the sucker rod that breaks, utilize the oil pipe being connected with pipe nipple upper end to continue upwards to lift window cutting dipper, just can fish for the sucker rod that breaks.Of the present utility model for salvaging the window cutting dipper of sucker rod, can in salvaging, sucker rod stop large-area crude oil pollution, and reduce and salvage cost, use manpower and material resources sparingly.
Brief description of the drawings
The following drawings is only intended to the utility model to schematically illustrate and explain, does not limit scope of the present utility model.Wherein:
Fig. 1: for the utility model is for salvaging the structural representation of window cutting dipper of sucker rod.
Fig. 2: for A in Fig. 1 is to view.
Detailed description of the invention
Understand for technical characterictic of the present utility model, object and effect being had more clearly, now contrast brief description of the drawings detailed description of the invention of the present utility model.
As shown in Figure 1 and Figure 2, the utility model proposes a kind of for salvaging the window cutting dipper 100 of sucker rod, described window cutting dipper 100 includes tubulose dipper body 1, dipper body 1 top is fixed with one section of connected pipes 2, and these connected pipes 2 tops are fixedly connected with (when operation, pipe nipple is connected with lower oil pipe in well) with a pipe nipple 3; On the tube wall of described dipper body 1, be relatively provided with two and window 11; Described windowing forms the window tongue 12 being tilted to towards dipper body interior on 11; Distance between described two relative window tongue 12 tops is less than the diameter of box cupling (not shown) on sucker rod.
In the time salvaging the disconnected sucker rod dropping in oil well, described window cutting dipper 100 moves down, the top of sucker rod is introduced in dipper body 1, then to window cutting dipper pressurization 5~8KN, while is due to the Action of Gravity Field of salvaging system self, window cutting dipper 100 enters down-hole smoothly, break the top of the sucker rod that falls also smoothly by two groups of positions of windowing, in the time that sucker rod passes through two relative window tongue 12 top spacings, although two window tongues can push and deformation owing to being subject to box cupling on sucker rod, but losing after extruding force (being that box cupling passes through), two window tongues can be because self elastic recovery be to heeling condition, when whole window cutting dipper is upwards lifted, two window tongue 12 tops just can be stuck in the box cupling lower end of the sucker rod that breaks, utilize the oil pipe being connected with pipe nipple upper end to continue upwards to lift window cutting dipper, just can fish for the sucker rod that breaks.
From the above mentioned, of the present utility model for salvaging the window cutting dipper of sucker rod, can in salvaging, sucker rod stop large-area crude oil pollution, and reduce and salvage cost, use manpower and material resources sparingly.
