Abstract
A packing is along with polish rod and well head horizontal migration formula prevent eccentric wear pumping well head polish rod sealing device. This follow-up formula is prevented partial wear and is pumped well head polished rod sealing device includes packing box (2), packing box (2) upper portion threaded connection have and screw up cap (9), screw up cap (9) upper end and be equipped with supporting sleeve (10), be equipped with packing bush (5) in packing box (2), be equipped with bush gasket (4) between packing bush (5) bottom surface and packing box (2), install packing (12) in packing bush (5), install packing gasket (3) between packing (12) and bush gasket (4), packing (12) top is equipped with gland (6), gland (6) top is equipped with gland gasket (7), gasket (8) in proper order. The device prolongs the pump detection period and the service life of the polish rod and the packing, further improves the time rate of the oil pumping unit, realizes the yield increase of crude oil and saves the cost of detecting the pump, the polish rod and the packing.
Description
Technical field
The utility model relates to well mouth sealing device in the oil recovery field, oil field, is a kind of Follow-up eccentric wear prevention pumping wellhead polish rod sealing device.
Background technology
In oil recovery field, oil field, at present, former mouth of pumped oil well polish rod seal device, the bulb of its underpart can not automatic aligning, produces that eccentric wear is prone to cause disconnected bar blowout, to change the packing time long, packing weak point in application life.The variation of environmental factor such as temperature and strong wind misaligns well head and polished rod, and the horizontal relative displacement of polished rod produces eccentric wear, heavy wear packing and polished rod.Cause polished rod to break and take off, need to shut down maintenance.When leakage of oil was become flexible in the packing wearing and tearing, shutdown added packing, and getting old packing wastes time and energy, and rate is up to standard when influencing oil pumper, and then influences stable production of crude oil.
Summary of the invention
But the utility model provides a kind of packing with polished rod and well head horizontal movable type eccentric wear prevention pumping wellhead polish rod sealing device; The application life of this device for prolonging pump detection period and polished rod and packing; And then rate when improving oil pumper, realize incremental oil production and the expense of practicing thrift inspection pump, polished rod and packing.
The technical scheme of the utility model is: this Follow-up eccentric wear prevention pumping wellhead polish rod sealing device comprises packing box, the described packing box top screwed cap that has been threaded, and the screwed cap upper end is provided with supporting sleeve; Be provided with the packing lining in the packing box; Be provided with the lining pad between packing lining bottom surface and the packing box, in the packing lining packing be installed, between packing and the lining pad packing pad is installed; The packing top is provided with gland, and the gland top is provided with gland pad, pad successively.
The utlity model has following beneficial effect: when (1) square clamp frontlighting bar glided, the servere injury accident of avoiding hindering hand took place.(2) the horizontal automatic aligning of the present invention's ability is prevented eccentric wear, anti-disconnected bar blowout, is reduced packing replacing time, the application life of prolongation packing and polished rod.(3) extract and install packing fast.Be beneficial to safety operation, cost is low, and is simple in structure, is convenient to install.Rate descends when avoiding oil pumper, realizes stable production of crude oil.
Description of drawings:
Accompanying drawing 1 is the structural representation of the utility model.
The 1-polished rod; The 2-packing box; 3-packing pad; 4-lining pad; 5-packing lining; The 6-gland; 7-gland pad; The 8-pad; The 9-screwed cap; The 10-supporting sleeve; The 11-bolt; The 12-packing.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1; This Follow-up eccentric wear prevention pumping wellhead polish rod sealing device comprises packing box 2, the described packing box 2 tops screwed cap 9 that has been threaded, and screwed cap 9 upper ends are provided with supporting sleeve 10; Supporting sleeve 10 supports the square clamp that the frontlighting bar glides, and the servere injury accident of avoiding hindering hand takes place.Be provided with packing lining 5 in the packing box 2; Packing lining 5 leaves the gap with packing box 2 inwalls; Be provided with lining pad 4 between packing lining 5 bottom surfaces and the packing box 2, packing 12 is installed in the packing lining 5, between packing 12 and the lining pad 4 packing pad 3 is installed; Packing 12 tops are provided with gland 6, and gland 6 tops are provided with gland pad 7, pad 8 successively.During polished rod 1 horizontal movement; Polished rod 1, lining pad 4, packing lining 5, packing 12, gland 6 form an integral body with gland pad 7; This whole generation relatively in level orientation with packing pad 3, pad 8 is slided; Make packing 12 and polished rod 1 centering, the principle of eliminating eccentric wear during the displacement of mouth of pumped oil well occurred level is identical, significantly alleviates the eccentric wear of polished rod 1 and packing 12.
During packing inefficacy blow-by, packing lining 5 and screwed cap 9 are connected through bolt.Be rotated counterclockwise the screwed cap 9 of packing box 2, packing lining 5 is extracted fast, can the old packing of easy to do taking-up.
Through field experiment, reached the design application target fully, implement the application life that the back prolongs pump detection period and polished rod and packing, and then rate when improving oil pumper, realize incremental oil production and practice thrift the expense of examining pump, polished rod and packing.Add packing shutdown 3h at every turn and reduce to 15min, year adds the packing number of times and drops to below 3 times by 12 times.Year taking off fault rate because of the eccentric wear generation is disconnected significantly descends.Also greatly reduce the labour intensity of changing packing, its economic benefit and social benefit are very significantly.
Claims (2)
1. but a packing is with polished rod and well head horizontal movable type eccentric wear prevention pumping wellhead polish rod sealing device; Comprise packing box (2), it is characterized in that: described packing box (2) the top screwed cap (9) that has been threaded, screwed cap (9) upper end is provided with supporting sleeve (10); Be provided with packing lining (5) in the packing box (2); Be provided with lining pad (4) between packing lining (5) bottom surface and the packing box (2), packing (12) is installed in the packing lining (5), between packing (12) and the lining pad (4) packing pad (3) is installed; Packing (12) top is provided with gland (6), and gland (6) top is provided with gland pad (7), pad (8) successively.
