Abstract
The utility model provides an upper sealant packing box for an oil field jack well, which is composed of a polish rod, a centralizer, a packing box, abrasion-proof sealant, a right injection hole, a left injection hole, a left chamfer head screw and a right chamfer head screw. The packing box is the substitution product of the old type packing. Making use of the abrasion-proof sealant as packing, the utility model increases the abradability of the packing and solves the well mouth serious oil leakage problem caused by the eccentric wear generated between the polish rod and the packing when the oil pumping polish rod has larger deviation with the center of a well mouth. The technique is convenient and simple to operate, and has visible economic benefit and social benefit.
Description
The utility model relates to a kind of sealed packing of sucker rod in the crude oil production, particularly is a kind of overhead sealant packing box.
Pumpingh well is in producing the crude oil process, drive oil well pump extraction crude oil by pumping of sucker rod, the sealing of well mouth of oil well is to finish by polished rod and packing above the sucker rod, because packing is to be placed in the packing box with asbestos cord or belt strip, compress by packing gland, this packing wears no resistance, and application life is short, easily causes the well head leakage of oil.When oil pumping polish rod and well head centre deviation are big, polished rod and packing produce eccentric wear and cause the serious leakage of oil of well head, even add a packing in one, two day and also can't resolve packing leakage of oil problem, not only increase labor intensity of operating personnel, nor safety, crude oil is produced in influence.
The purpose of this utility model just provides a kind of overhead sealant packing box, utilizes the wear-resistant seal agent to do packing, improves the abrasion resistance of packing, reduces the well head leakage of oil, reduces labour intensity, and favourable safety in production increases crude output.
Above-mentioned purpose is realized by following technical proposals:
Overhead sealant packing box is by polished rod, centralizer, packing box, wear-resistant seal agent, right injection hole and left injection hole, and left sunk screw and right sunk screw are formed.
Polished rod is contained in the polished rod centralizer, and on the polished rod centralizer, there is right injection hole on packing box the right on the packing box, and there is left injection hole on the packing box left side, and two sunk screw shutoff are arranged.The wear-resistant seal agent forms the sealant packing with the annular space of high pressure injection polished rod and packing box.
After technique scheme enforcement, the application life of packing is than prolonging greatly originally, reduced the leakage of oil of well head, because wear-resistant seal agent packing can encase oil pumping polish rod uniformly, solved oil pumping polish rod and well head centre deviation when big, polished rod causes the serious leakage of oil problem of well head with packing generation eccentric wear, and this technical operation is convenient and simple, alleviate labor intensity of operating personnel, had remarkable economic efficiency and social benefit.
Accompanying drawing 1, accompanying drawing 2 are sectional structure chart of the present utility model and vertical view.
In conjunction with the accompanying drawings embodiment of the present utility model is described below:
1 is polished rod among the figure, the 2nd, and polished rod centralizer, the 3rd, packing box, the 4th, wear-resistant seal agent, the 5th, right injection hole, the 6th, left injection hole, the 7th, left sunk screw, the 8th, right sunk screw.Constitute overhead sealant packing box by above each parts.The polished rod 1 polished rod centralizer 2 of packing into, on the packing box 3 in polished rod centralizer 2 upper ends, on the left sunk screw 7 on left injection hole 6, be stuck on the packing box 3 with having the colloid-injecting gun that injects the high pressure sealing agent, inject wear-resistant seal agent 4 from right injection hole 8 high pressure, use then on the right sunk screw 8 on right injection hole 5.For the wear-resistant seal agent 4 in the packing box 3 is evenly distributed, in like manner can inject wear-resistant seal agent 4 at left injection hole 6 high pressure, increase sealing effectiveness.
Claims (1)
