Abstract
A kind of anti-pumpingh well fueling injection equipment, belongs to oil extraction in oil field field of mechanical technique, which includes blowout-preventing ball seat, spindle plug, packing box pressing cap, packing platen, packing, packing box.Packing box and the packing suit being sleeved on polished rod link together, it covers and is threadedly coupled in polished rod upper packing box pressing cap upper end with blowout-preventing ball seat, packing platen is connect with packing box pressing cap mid-section threads, assembled packing box pressing cap is threadedly attached on original packing box for pumping well, is sleeved on the spindle plug on polished rod and is located in the cavity of blowout-preventing ball seat and packing box pressing cap.After polished rod occurs disconnected de-, spindle plug can play the role of blocking sealing automatically, prevent well oil gas mixed liquor from spraying, and oil spout contamination accident is avoided to occur；Packing box pressing cap cavity is provided with note lubricating oil, guarantees when polished rod pumps and the lubrication of packing.
Description
Technical field
The utility model belongs to oil extraction in oil field field of mechanical technique, in particular to a kind of to have the anti-oil pumping blowout of light rod-broken
Oily dedicated unit.
Background technique
Currently, most oilfields pumpingh well is all to carry out oil recovery production using sucker rod pump, polished rod is rod pumping system
In an important component.Polished rod passes through wellhead assembly and packing box, and entire rod string is hung over by optical-rod clamp
On polished rod eye.Since polished rod bears horse head stress alternation at work, pump, and due to well oil corrosion,
Polished rod attenuates with packing friction, therefore disconnected de- phenomenon often occurs.Pit shaft is fallen into after light rod-broken, packing box is now in nothing
Control state, the oil-gas mixture in oil well spray well head, cause oil spout contamination accident.In addition, with the increasing of the oil field development time limit
Add, water content in crude oil increases year by year, and polished rod and its sealed packing greasy property is caused to be deteriorated, and friction aggravation is easy to cause oil well
Well head packing and polished rod reduced service life, cause polished rod to be broken.To sum up, it is necessary to a kind of grease proofing well fueling injection equipment is studied, with
It solves light rod-broken and enters crude oil self-spray after well, it is ensured that crude oil normally produces.
Summary of the invention
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of grease proofing well fueling injection equipment,
The technical solution adopted in the utility model is: a kind of grease proofing well fueling injection equipment, the device include blowout-preventing ball seat, spindle
Body plug, packing box pressing cap, packing platen, packing and packing box.It is bell shape, spindle with externally threaded blowout-preventing ball seat inner cavity
Body plug is the spindle shape of both ends semicircle sphere middle with hole, and packing box pressing cap is upper and lower part band internal thread sleeve-shaped,
Packing platen is nut-shaped of the top with external screw thread and sealing ring, and packing is up big and down small cone staving shape, packing box and packing
Interconnecting piece is up-small and down-big cone staving shape.Packing box and the packing suit being mounted on polished rod link together, and are mounted on light
Packing box pressing cap upper end on bar is threadedly coupled with blowout-preventing ball seat, and packing platen is connect with packing box pressing cap mid-section threads, assembling
Good packing box pressing cap is threadedly attached on original packing box for pumping well.The spindle sphere plug being sleeved on polished rod is located at
In the cavity of blowout-preventing ball seat and packing box pressing cap.
Grease proofing well fueling injection equipment using the above structure, before installation, blowout-preventing ball seat inner cavity and the injection of packing box pressing cap inner cavity
Lubricating oil, after being mounted on polished rod, polished rod is always in cavity oil indoor activity, it is ensured that the profit that polished rod pumps with packing
It is sliding.After generation light rod-broken enters well, spindle plug loses the fixation of polished rod, and when spraying in oil stream, spindle plug is in oil
It is risen rapidly under the impetus of stream, plug spherical surface and blowout-preventing ball seat cooperate, and block oil circuit, reach and block oil stream ejection well head
Effect.
The remarkable result of the utility model are as follows: first is that spindle plug and blowout-preventing ball seat cooperate, energy after disconnected take off occurs for polished rod
Automatically play the role of blocking sealing, prevent well oil gas mixed liquor from spraying, oil spout contamination accident is avoided to occur；Second is that packing box
Lubricating oil can be filled in pressure cap cavity, guarantee lubrication when polished rod pumps.
Detailed description of the invention
Fig. 1 is the utility model structure diagram.
Fig. 2 is spindle plug closure oil circuit schematic diagram after polished rod break.
It is as shown in the figure: 1- polished rod；2- blowout-preventing ball seat；3-O type sealing ring；4- spindle plug；5- packing box pressing cap；6- is close
Seal；7- packing platen；8- packing；9- packing box.
Specific embodiment
Specific embodiment of the present utility model combination attached drawing is illustrated.
As shown in Figure 1, a kind of anti-pumpingh well fueling injection equipment, which includes blowout-preventing ball seat 2, spindle plug 4, packing box
Pressure cap 5, packing platen 7, packing 8, packing box 9.Packing box 9 and packing 8 suit being mounted on polished rod link together, then
Packing platen 7 and packing box pressing cap 5 are sequentially sleeved on polished rod, then spindle plug 4 is covered on polished rod also by its hole, most
Blowout-preventing ball seat 2 is packed into polished rod afterwards, packing box pressing cap upper end is threadedly coupled with blowout-preventing ball seat, packing platen 7 and packing box pressing cap
Mid-section threads connection, assembled packing box pressing cap are threadedly attached on original packing box for pumping well 9.It is sleeved on polished rod
Spindle plug 4 be located in the cavity of blowout-preventing ball seat and packing box pressing cap, the material of spindle plug is polytetrafluoroethylene (PTFE).
As shown in Fig. 2, spindle plug loses the support of polished rod, spindle plug when pumping well polish rod occurs disconnected de-
It is risen rapidly under the impetus of oil stream, plug microcephaly spherical surface and blowout-preventing ball seat cooperate, and block oil circuit, block oil stream and spray well
Mouthful.
