Abstract
The present invention provides a kind of non-return type storm valve opening tool, including main body, and body top is equipped with positive stop lug boss, and lower body part is equipped with retaining leather cup, and lower body part is equipped with groove, and the expanding structure on retaining leather cup top is located in groove.The beneficial effects of the invention are as follows：Storm valve opening tool, which is sent to push after downhole safety valve position by coiled tubing, to open the safety-valve, after the limit of body top boss, retaining leather cup prevents from pushing up on opening tool, in the case where not playing out the flow string with safety valve, the opening state of safety valve is opened and maintained always to storm valve by latus rectum continuous oil pipe operation.Latus rectum is big and smooth in the device, and locking is reliable, and does not injure storm valve.
Description
Technical field
The present invention relates to oil extraction in oil field, well workover kit technical fields, more specifically to non-return type downhole safety
Valve opens tool.
Background technology
Storm valve is in high-pressure gas well or whale, after preventing oil gas loss of well control, oil gas water to overflow out of well
Go out to pollute well site ground, ocean and air, causes environmental pollution.
For oil well in normal productive process, safety valve needs ground special pressure system that certain pressure is maintained just to can guarantee
Safety valve is in the open state, once geostatic pressure releases or dispatch tube leaks, safety valve can be in the effect of borehole pressure
Under voluntarily close, oil well is in end-of-life state.
With the progress of production, when high-pressure oil-gas well pressure reduction no longer needs safety valve, dismountable ground maintains safety
The pressure system that valve is opened, to reduce energy consumption；Once pressure system is removed, storm valve will be closed, dismantle
Geostatic pressure system and it is constantly in the case of not playing out the flow string with storm valve how downhole safety to beat
Open state, this just needs the opening tool of design specialized to realize.
Invention content
The present invention overcomes deficiencies in the prior art, provide a kind of non-return type storm valve opening tool, structure
Simply, internal diameter is smooth, and locking is reliable.
The purpose of the present invention is achieved by following technical proposals.
A kind of non-return type storm valve opening tool, including main body, the body top are equipped with positive stop lug boss, the master
Body lower part is equipped with retaining leather cup, and the lower body part is equipped with groove, and the expanding structure on retaining leather cup top is positioned at described recessed
In slot.
Further, the retaining leather cup vulcanization is in the body surfaces.
Further, the lower diameter of the retaining leather cup is not more than lower body part diameter.
Further, the diameter of the expanding structure is more than latus rectum in the lower body part diameter and safety valve.
Further, the lower body part diameter is less than latus rectum in the safety valve.
Further, the diameter of the positive stop lug boss is more than the diameter of latus rectum in the safety valve.
Further, the length of the main body is more than the length of the interior latus rectum of the safety valve.
Further, the inside of the main body upper end and the inside of lower end are respectively equipped with guiding cambered surface.
Beneficial effects of the present invention are：The storm valve opens tool and is sent to downhole safety valve position by coiled tubing
It pushes and opens the safety-valve afterwards, after the limit of body top boss, retaining leather cup prevents from pushing up on opening tool, is not rising out with safety
In the case of the flow string of valve, the opening of safety valve is opened and maintained always to storm valve by latus rectum continuous oil pipe operation
State.Latus rectum is big and smooth in the device, and locking is reliable, and does not injure storm valve.
Description of the drawings
Fig. 1 is the cross-sectional view of the structure of the present invention；
Fig. 2 is safety valve and assembling figure of the present invention；
In figure：
1, main body；1.1, cambered surface is guided；1.2, positive stop lug boss；1.3, groove；1.4, cambered surface is guided；
2, retaining leather cup；2.1, the expanding structure in top；3, safety valve.
Specific implementation mode
Technical scheme of the present invention is further described below by specific embodiment.
A kind of non-return type storm valve opens tool, including main body 1 as shown in Figs. 1-2, and 1 lower diameter of main body is less than peace
Latus rectum in full valve 3, the length of main body 1 are more than the length of the interior latus rectum of safety valve 3；1 upper end of main body is internally provided with guiding cambered surface
1.1, being internally provided with for 1 lower end of main body guides cambered surface 1.4；The guiding effect of cambered surface 1.1,1.4 is the tool that guiding passes through, and is realized suitable
Profit passes through；
1 top of main body is equipped with positive stop lug boss 1.2, and the diameter of positive stop lug boss 1.2 is more than the diameter of latus rectum in safety valve 3；It is main
The vulcanization of 1 lower part of body is equipped with retaining leather cup 2, it is preferred that retaining leather cup 2 is rubber material, and 1 lower part of main body is equipped with groove 1.3, retaining
The expanding structure 2.1 on 2 top of leather cup is located in groove 1.3, and retaining leather cup 2 receives external force rubber annular strain and stretches during lower section
It is long, it is dissolved in groove 1.3；
The lower diameter of retaining leather cup 2 is not more than 1 lower diameter of main body；The diameter on 2 top of retaining leather cup is more than under main body 1
Internal diameter at portion's diameter and safety valve 3.Retaining leather cup 2 is to prevent from pushing up on opening tool, and retaining leather cup 2 is bell shape.?
It is retracted in groove 1.3 into being become smaller in the process, when crossing 3 undergauge of safety valve by elongation outer diameter, when by upper top power, at this time
Groove 1.3 is located at the top of retaining leather cup 2, in the excessive groove 1.3 that can not again return to main body 1 of the volume of retaining leather cup 2,
Locking is reliable, and only rubber cutting could be ejected, this shear strength is also very big.
The course of work：After the 3 opening tool of storm valve is put into flow string, with coiled tubing work vehicle pipe
Capital to 3 position of storm valve is pushed with tubing string and opens storm valve 3, and 2 outer diameter of retaining leather cup is more than storm valve
3 internal diameters, after can not backed off after random, always maintain safety valve 3 opening state.Latus rectum is big and smooth in the device, and locking can
It leans on, and does not injure storm valve 3.
One embodiment of the present invention has been described in detail above, but the content be only the present invention preferable implementation
Example should not be construed as limiting the practical range of the present invention.It is all according to all the changes and improvements made by the present patent application range
Deng should all still fall within the scope of the patent of the present invention.
