Description
Technical field
The present invention relates to petroleum technology fields, and in particular to a kind of oil field shaft mouth oil spout blocks device.
Background technique
Petroleum is the main energy sources resource of modern industry, is a hiding entity, in recovery process under the burial ground of oil field
In, interior oil, gas and water are constantly flowed, are vary, and this rheological characteristic is the spy that other solid mineral reserve do not have
Point.Currently, in having bar oil recovery process, it some times happens that the polished rod fracture accident at the top of sucker rod.Pumping unit installation foundation compared with
Low, polished rod eye clamping plate bottom is big compared with small and dead space with a distance from packing box, and polished rod broken end will fall into packing box hereinafter, deep-well pump plunger shaft
Plug is sat extremely in pump barrel, and oil well stops production and well head is in runaway condition, and the defeated manifold of oil gas sum aggregate flows back into a large amount of oil well
Gas mixture will come out from well head jet flow, cause vast resources waste and large area environmental pollution, cause certain loss.
Summary of the invention
In view of the foregoing drawbacks or insufficient, the purpose of the present invention is to provide a kind of oil field shaft mouth oil spouts to block device.
To achieve the above objectives, the technical solution of the present invention is as follows:
Including the polished rod being set in oil well, shell is provided on the outside of polished rod, the top of shell is equipped with polished rod is tight
Solid wedge block, be provided with cavity on shell, position corresponding with cavity, which is provided with, blocks room, blocks to be equipped in room and is used for
The sphere of cavity is blocked, the baffle being equipped in room for stopping sphere to slide is blocked.
The bottom end for blocking room is provided with sliding slot.
The motor for driving baffle to move upwards is provided on the baffle.
The sphere is sphere made of steel or building stones.
Compared with the prior art, the invention has the benefit that
The present invention provides a kind of oil field shaft mouth oil spouts to block device, blocks room by setting and for blocking cavity
Sphere blocks steel ball by baffle in inoperative, and when leakage, by pulling out baffle, steel ball enters cavity, obstructs back
Road prevents the gas mixture that the defeated manifold of oil gas sum aggregate flows back into oil well that will go out from well head jet flow, avoids the wasting of resources
With large area environmental pollution, and component of the invention is easily purchased, and without especially processing, is reduced the cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that oil field shaft mouth oil spout of the present invention blocks device.
Specific embodiment
The present invention will be described in detail with reference to the accompanying drawing.
As shown in Figure 1, the present invention provides a kind of oil field shaft mouth oil spouts to block device, including the polished rod being set in oil well
1, the outside of polished rod 1 is provided with shell 2, and the top of shell 2 is equipped with the wedge block 3 for fastening polished rod 1, is provided on shell 2
Cavity 6, position corresponding with cavity 6, which is provided with, blocks room 4, blocks the sphere being equipped in room 4 for blocking cavity 6, envelope
Baffle 5 for stopping sphere to slide is installed, the bottom end for blocking room 4 is provided with sliding slot, in addition, of the invention in stifled room 4
In the baffle 5 on be provided with motor for driving baffle to move upwards, facilitate the promotion of baffle.It is described in the present invention
Wedge block 3 is in inverted ladder shape.
In order to enable blockage effect is obvious, the sphere is sphere made of steel or building stones.
The course of work of the invention are as follows:
In inoperative, steel ball is lived by baffle gear 5, when leakage, by pulling out baffle 5, steel ball enters cavity 6,
Circuit is obstructed, prevents the gas mixture that the defeated manifold of oil gas sum aggregate flows back into oil well that will go out from well head jet flow, avoids money
Source waste and large area environmental pollution.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent thereof.
