Description
Technical field
The invention belongs to oil well blowout-prevention technical fields, are related to a kind of oil well no killing well blowout prevention down-hole switch device.
Background technique
With the Devoting Major Efforts To Developing in oil field, the raising of DP technology, oil well Advance Water Injection technique obtains in the exploitation in oil field
It is widely applied, which can be improved the yield of oil well early period, can be there is also certain insufficient, such as the oil well of Advance Water Injection
In lower Tubing During Running, oil can be sprayed from oil pipe, polluted environment, the difficulty of workover treatment is increased, currently, to most of oil
For field, water injection technology is all implemented, for strata pressure generally all in more than 20 MPa, oil recovery process is that spray and pumping exist simultaneously, and is had
A little wells are directly self-spray forms, are had seriously polluted the environment, and blowout prevention problem becomes Advance Water Injection oil well urgent problem.And mesh
The preceding only water conservancy kill-job that can be used, operating cost is high, and operation difficulty is big, polluted reservoir, influences oil well output and extraction oil
Quality.Market needs a kind of can solve the problem and simple and easy to operate tool to solve oil pipe when lower well operations and prevent
Spray problem.
Summary of the invention
Present invention aims to overcome that the defect of the above-mentioned prior art, provides a kind of oil well no killing well blowout prevention down-hole switch dress
It sets, it can be when carrying out underground work to oil well, only need to push sucker rod can close pit shaft, reach the mesh for preventing oil well oil spout
's.
The present invention is to be achieved through the following technical solutions:
This oil well no killing well blowout prevention down-hole switch device, including top connection, outer cylinder, relief valve, guide way, spring base and
Spring pocket；The top connection is connected with outer cylinder；The guide head is connected with relief valve and one end of top connection inner cavity is arranged in, and leads
To the first spring is equipped between head and relief valve, the inner cavity of outer cylinder is equipped with guide way, the both ends difference of the guiding intracoelomic cavity
Equipped with spring base and spring pocket, spring base is connected with spring pocket by second spring；The right end of the spring pocket is equipped with valve mouth.
There is lead key on above-mentioned guide way.
Compared with prior art, the invention has the following beneficial technical effects:
The present invention is mounted between tubing pump and standing valve, and the tool is that relief valve is closed when lower pump, liquid in well
Oil pipe cannot be entered by oil well pump.When arriving predetermined position, then lower piston and sucker rod under oil well pump.When piston enters pump barrel
Afterwards, guide head is pushed with piston, guide head, which pushes, plays spring base drive guide way downlink, and relief valve is first opened, and realizes that pressure is flat
Weighing apparatus, continues to push, and guide way continues to move down, and opens valve mouth, and liquid enters pump barrel by guide way open slot, realizes normal
Oil pumping.It can be when carrying out underground work to oil well, and only need to push sucker rod can close pit shaft, oil well can be effectively prevent to spray
Oil.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Wherein: 1 top connection, 2 guide heads, 3 first springs, 4 relief valves, 5 spring bases, 6 guide ways, 7 second springs, 8 lead
Key, 9 outer cylinders, 10 spring pockets, 11 valve mouth.
Specific embodiment
The invention will be described in further detail with reference to the accompanying drawing, and the explanation of the invention is not limited.
Referring to Fig. 1, a kind of oil well no killing well blowout prevention down-hole switch device, including top connection 1, outer cylinder 9, relief valve 4, guiding
Body 6, spring base 5 and spring pocket 10；Top connection 1 is connected with outer cylinder 9；Guide head 2 is connected with relief valve 4 and top connection 1 is arranged in
One end of inner cavity, is equipped with the first spring 3 between guide head 2 and relief valve 4, the inner cavity of outer cylinder 9 is equipped with guide way 6, in guide way 6
The both ends of chamber are respectively equipped with spring base 5 and spring pocket 10, and spring base 5 is connected with spring pocket 10 by second spring 7；Spring pocket
10 right end is equipped with valve mouth 11.Guide way 6 also on have a lead key 8, and lead key 8 passes through the barrel of outer cylinder 9.
In use, the present invention is mounted between tubing pump and standing valve, the tool is that relief valve 4 is closed when lower pump,
Liquid cannot enter oil pipe by oil well pump in well.When arriving predetermined position, then lower piston and sucker rod under oil well pump.When piston into
After entering pump barrel, guide head 2 is pushed with piston, guide head 2, which pushes, plays drive 6 downlink of guide way of spring base 5, and relief valve 4 is first opened,
Realize pressure balance, continue to push, guide way 6 continues to move down, make valve mouth 11 open, liquid by 6 open slot of guide way into
Enter pump barrel, realizes normal oil pumping.
The present invention can be when carrying out underground work to oil well, and only need to push sucker rod can close pit shaft, and reaching prevents oil
The purpose of blowout oil.
