Abstract
A drag reduction multifunctional well plugging device mainly solves the problem of serious friction between a polish rod and a packing set in the prior well plugging device. The device is characterized in that after a bias-adjusting ball (2) is connected with a packing box (10), a blowout control ball (5) is fixed in a cavity where a base (1) is combined with the lower end of the bias-adjusting ball (2) through a blowout control ball clamping seat (4), and a rubber oil seal (6) and a gasket (7) are fixed in a cavity where the lower end of the packing box (10) is combined with the upper end of the bias-adjusting ball (2); a lubricating ring (11) is fixed in an inner cavity at the upper end of the packing box (10), is compressed through a packing box gland (12), and has an inner layer and an outer layer, wherein screen meshes are drilled on the inner wall of the inner layer, an annular groove is formed on the outer wall of the inner layer, the screen meshes are communicated with the annular groove, and an oil hole is drilled on the outer layer and is communicated with the annular groove formed on the outer wall of the inner layer. The well plugging device can reduce the friction of the polish rod on the packing set, and the polish rod can be fixed only by the rotation of the packing box.
Description
Technical field:
Used servicing unit when the utility model relates to the oil field shaft mouth operation relates to a kind of blowout preventer specifically.
Background technology:
In the oil recovery field, for preventing crude oil leakage, production wellhead all is equipped with blowout preventer at present, but existing these blowout preventers are owing to reasons in structure, and the friction between polished rod and the packing is more serious, make horse head load increase, finally cause packing fragile, increased maintenance cost.In addition, in changing the packing construction, polished rod often occurs, use this blowout preventer and need use fixedly polished rod of conventional method from the situation that suspension point comes off, complex process, workman's inconvenient operation has reduced operating efficiency.
The utility model content:
For solve use existing blowout preventer cause friction between polished rod and the packing serious and when changing packing fixedly polished rod technology than complicated problems, the utility model provides a kind of drag reduction multifunctional capping device, this kind drag reduction multifunctional capping device can reduce the friction of polished rod to packing, and when changing packing, only need rotate fixedly polished rod of packing box, have long service life, can improve the characteristics of operating efficiency.
The technical solution of the utility model is: this kind drag reduction multifunctional capping device, comprise base, tuningout ball, packing box and packing box gland etc., wherein said tuningout ball is with after packing box connects, be anchored on the base by tuningout ball gland, wherein, in the cavity at described base and tuningout ball lower end place linked together, be fixed with a spray-proof ball, in the cavity at the lower end of described packing box and tuningout ball upper end place linked together, be fixed with rubber oil sea and pad by the spray-proof ball deck; Be fixed with a drip ring at the upper end of described packing box inner chamber, described drip ring compresses by the packing box gland, described drip ring has inside and outside two-layer, the internal layer inwall is drilled with mesh, inner layer outer wall then has cannelure, and wherein, mesh communicates with cannelure, skin is drilled with an oil filler point, and oil filler point is connected with the cannelure of opening in inner layer outer wall.
In addition,, an annular shoulder can be arranged, have groove all around at this annular shoulder in the external stability of packing box for ease of fixing polished rod when changing packing.
The utlity model has following beneficial effect: owing to take such scheme, the drip ring of packing top has inside and outside two-layer, and the internal layer inwall is drilled with mesh, and mesh communicates with the inner layer outer wall cannelure.Skin is drilled with an oil filler point, and oil filler point links to each other with the internal layer cannelure, adds machine oil from oil filler point, and machine oil is stored in the cannelure, and by the lubricated polished rod of mesh seepage.Thereby reduced the frictional resistance of polished rod and packing, prolonged the application life of packing.In addition, when changing packing, be stuck on the packing box shoulder by special tool, clockwise rotate packing box, make the descending compressing rubber oil sealing of packing box, the rubber oil sea compressive deformation is held polished rod tightly, makes the construction of replacing packing become safe and efficient, can improve operating efficiency.
Description of drawings:
Fig. 1 is a structure sectional view of the present utility model.
Fig. 2 is the sectional drawing of shoulder in the utility model.
1-base among the figure, 2-tuningout ball, 3-tuningout ball gland, 4-spray-proof ball deck, 5-spray-proof ball, 6-rubber oil sea, 7-pad, 8-joint ring, 9-shoulder, 10-packing box, 11-drip ring, 12-packing box gland.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, this kind of drag reduction multifunctional capping device, comprise base 1, tuningout ball 2, packing box 10 and packing box gland 12 etc., wherein said tuningout ball 2 is with after packing box 10 connects, be anchored on the base 1 by tuningout ball gland 3, wherein, in the cavity at described base 1 and place linked together, tuningout ball 2 lower ends, be fixed with a spray-proof ball 5, in the cavity at lower end and the tuningout ball 2 upper ends place linked together of described packing box 10, be fixed with rubber oil sea 6 and pad 7 by spray-proof ball deck 4; Be fixed with a drip ring 11 at the upper end of described packing box 10 inner chamber, described drip ring 11 compresses by packing box gland 12, described drip ring 11 has inside and outside two-layer, the internal layer inwall is drilled with mesh, inner layer outer wall then has cannelure, and wherein, mesh communicates with cannelure, skin is drilled with an oil filler point, and oil filler point is connected with the cannelure of opening in inner layer outer wall.
During use, because the drip ring of packing top is two-layer inside and outside having, the internal layer inwall is drilled with mesh, and mesh communicates with the inner layer outer wall cannelure.Skin is drilled with an oil filler point, and oil filler point links to each other with the internal layer cannelure, adds machine oil from oil filler point, and machine oil is stored in the cannelure, and by the lubricated polished rod of mesh seepage.Thereby reduced the frictional resistance of polished rod and packing, prolonged the application life of packing.
In addition for ease of fixing polished rod when changing packing, an annular shoulder 9 can be arranged in the external stability of packing box 10, have groove around this annular shoulder 9, when changing packing, be stuck on the packing box shoulder by special tool, clockwise rotate packing box, make the descending compressing rubber oil sealing of packing box, the rubber oil sea compressive deformation is held polished rod tightly, makes the construction of replacing packing become safe and efficient, can improve operating efficiency.
