Abstract
The utility model relates to a reconstruction sealing device of a pumping well packing box, which is applied to a wellhead packing box of the pumping well with a rod. The device is characterized in that a lathe dog is composed of a left and a right separated lathe dogs, screw threads are arranged on the upper end of an inner hole of a round lathe dog, the diameter of the lower end of the inner hole of the lathe dog is equal to the outer diameter of a pressing cover of an original packing box. The lathe dog can be fast clamped on the top end of the original packing box through a fixed screw bolt, a cylindrical packing filling chamber is connected with threads on the upper end of the inner hole of the lathe dog, and a sealing packing is arranged in the packing filling chamber, and a packing box pressing cover is connected with the threads on the upper end of the packing filling chamber. The utility model has beneficial effects that the device can be connected on the upper portion of the original packing box of the oil well, the reconstruction of the wellhead sealing of the pumping well when a rubber lock gate is loose, the packing box is pierced through or is in a state of critical out of controlling can be realized, the generation of leaking oil of the wellhead can be prevented, the normal production of an individual well can be maintained, the time rate of extracting oil of the individual well can be improved, and the safety of the oil extracting well and the environment protection production can be guaranteed.
Description
Technical field
The utility model relates to oil recovery technique field, oil field, and particularly a kind of well head packing box of sucker rod pumping well is a kind of auxiliary sealing device of pumpingh well well head packing box.
Background technology
At present, production wellhead adopts packing box sealing well head.As the Chinese patent notification number is CN2755271Y, discloses a kind of pumpingh well polished rod sealer, comprises packing box, packing, back of the body cap, spring and deviation correcting device.Deviation correcting device comprises bias-proof joint, bulb pressure cap, bulb sealing and the lower contact that is coupled to each other.Packing box top connects the primary seal body, and the bottom connects deviation correcting device, installs master root and standby packing in the packing box, installs gland and jube therebetween.Adopt the level Four hermetically-sealed construction, improved sealing performance.
The well head sealed packing of sucker rod pumping well has certain application life, needs often to change, and is not tight as pumpingh well well head rubber gate (or subordinate's packing) when changing packing, can cause oil, gas thorn to leak, and packing is changed difficulty or can not in time be changed.Under well head oil pressure condition with higher, maintenance or replacing rubber gate must be wanted closing well or kill job, rate when influencing individual well production.
In addition, flowing well changes the initial stage of oil pumping, can cause packing box thorn leakage control when the well head oil pressure is higher, leads to environmental pollution accident.
The utility model content
The purpose of this utility model is: provide a kind of pumpingh well packing box to rebuild sealing device, realize the well head sealing under the improper production status of oil well; When leakage is controlled at contingent packing box thorn, rebuild a packing box sealing device on packing box top, prevent when the not tight or former packing box poor sealing of rubber gate the generation of well mouth of oil well oil leak accident, rate when improving single well production is guaranteed pumpingh well safety, environmental protection production.
The technical solution adopted in the utility model is: the pumpingh well packing box is rebuild sealing device and mainly is made up of parts such as clip, packing filling storehouse, packing pressure cap, packing glands:
Clip by about two branch hoops form, two branch hoops lump together and form a circular clip, there is screw thread the endoporus upper end of circular clip, the endoporus lower end diameter of circular clip is identical with the external diameter of former packing box gland.There is fixing hole the both sides of two branch hoops, and set bolt is arranged in the fixing hole.Clip can be clamped on the top of former packing box gland by set bolt.Screw thread is connected with packing filling cylindraceous storehouse in clip endoporus upper end.In the packing filling storehouse, sealed packing is arranged.Screw thread is connected with the packing box gland in the upper end in packing filling storehouse.Rotation packing box gland, sealed packing just can play the oil-extractor polish-rod sealing function.
Can compress packing in order to rotate the packing box gland, in the packing box gland, and a packing box pressure cap be arranged at the top of sealed packing.
For sealing, between packing filling storehouse and former packing box gland, 0 shape sealing ring is arranged.
The beneficial effects of the utility model: the pumpingh well packing box is rebuild sealing device, and this device can be connected the former packing box top of oil well, plays further sealing function.Can realize that pumpingh well is tight at the rubber gate, the packing box thorn is missed and rebuild the well head sealing under control or the critical runaway condition, prevent the generation of well head oil leak accident, and keep the individual well ordinary production that rate when improving single well production is guaranteed pumpingh well safety, environmental protection production.
Description of drawings
Fig. 1 is that the utility model pumpingh well packing box is rebuild the sealing device structure generalized section.
Among the figure, 1. former packing box, 2. former packing box gland, 3. clip, 4. set bolt, 5. packing filling storehouse, 6. packing box gland, 7. polished rod, 8. packing box pressure cap, 9. sealed packing, 10.O shape sealing ring.
The specific embodiment
Embodiment 1:
Consult Fig. 1.The utility model pumpingh well packing box is rebuild sealing device and mainly is made up of parts such as clip 3, packing filling storehouse 6, packing pressure cap 9, packing glands 7:
Oil pressure occurs after the new well commentaries on classics of Xinjiang Oilfield Company card six wellblock K1137 is taken out and raise, recovered certain blowing ability, output is higher, finds when changing packing that the rubber gate is not tight, can't change the packing operation.For keeping the oil well ordinary production, avoid closing aboveground repairing and change the rubber gate, develop the pumpingh well packing box specially and rebuild sealing device, this well has recovered ordinary production after trying out.
