Abstract
The utility model relates to a multifunctional mine mouth polished rod sealer for the production of pump wells, comprising a stand 1, a lower gland 2, an adjusting deviation seat 3, a packing 4, a middle nodule 5, a second level sealing device 6, a blowout control box 7, a blowout control device 8, a first level sealing device 9, a packing box 10 and an upper gland 12. The polished rod sealer has reasonable structure and reliable work and convenient operation, has multiple functions of deviation prevention, seal and blowout control or the like, can be used to solve the problems of unevenly stress to polished rods of pump wells, partial wear of polished rods and packing materials and a large quantity of maintenance work or the like, can cut down labor intensity of workers and production cost, prevents well blowout and environmental pollution, and is suitable for generalization.
Description
Technical field:
The utility model relates to a kind of wellhead assembly that pumpingh well is produced that is used for, and belongs to mechanical oil recovery device class.
Background technology:
Wellhead polish rod sealer is a requisite important wellhead assembly during pumpingh well is produced, and at present, the wellhead polish rod sealer of oil field field by using adopts the rubber packing more, and does not have anti-eccentric and well blowout preventing device.In this case, the polished rod discontinuity, airtight and watertight padding is easy to wear, and maintenance is frequent, in case the polished rod fracture takes place, will cause gas blowout accident and environment pollution, is unfavorable for oil security and ordinary production.
Summary of the invention:
The purpose of this utility model is to provide a kind of polished rod off-centre, airtight and watertight padding of can preventing easy to wear, thereby can prolong airtight and watertight padding application life, reduce maintenance load, and can prevent the multifunctional well head polished rod sealer of blowout and environment pollution.
The utility model is achieved in that this kind wellhead polish rod sealer is made up of deck, lower cover, tuningout seat, packing, middle segmentum intercalaris, primary seal device, two stage sealing device, blowout prevention box, blowout hookup, packing box and upper press cover.Deck top inner headed face and the tuningout seat bottom periphery that sealing ring is housed on it suit that matches, its external application lower cover is tightened with screw thread, and tuningout seat top inner headed face round platform is to be equipped with packing in the epicoele; Tuningout seat top periphery is connected with the middle segmentum intercalaris of screw thread with its top, two stage sealing device, blowout prevention box and the sealing device of middle segmentum intercalaris and top thereof be welding mutually successively, blowout prevention box one side between the two-stage sealing device is equipped with blowout hookup, in the packing box of primary seal device top packing is housed, upper press cover is equipped with in the upper end.During use, with the two-stage sealing device of this polished rod sealer all pine and its cover installed on the polished rod to free state, the deck of sealing device lower end is fastening with the clamp connection of production tree usefulness; Hang up oil pumper load, adjust the inclined to one side seat of bottom adjuster, make sealing device and sucker rod centering, locking tuningout seat; Packing is added in the packing box of top, tighten upper press cover, pumpingh well can put into production.In the installation process, screw upper press cover clockwise, compressible packing makes it to seal polished rod.Clockwise precession primary seal device both sides push rod can make the sealing block in it hold polished rod tightly, when sealing block or packing filling wearing and tearing need to change, can be behind left alone without help oil pumper, close two stage sealing device, then, take out the top packing filling, use special tool to take out the interior sealing block of primary seal device, pack into new packing and sealing block screw upper press cover, hold out against primary seal, open secondary seal, start is produced.When polished rod ruptured, the spring in the blowout hookup pushed steel ball in the blowout prevention box, utilizes oil well pressure to seal well head, can play the effect that prevents blowout and pollution.
The utility model is rational in infrastructure, reliable operation, easy to operate, have anti-partially, multiple functions such as sealing, blowout prevention, utilize it can solve problems such as pumpingh well polished rod unbalance stress, polished rod, airtight and watertight padding eccentric wear and maintenance load are big, reduce labor strength and cost of production, prevent blowout and environment pollution, be suitable for and apply.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.Number in the figure " 25 " is the pumpingh well polished rod.
The specific embodiment: enforcement of the present utility model is described further below in conjunction with accompanying drawing.
As shown in the figure, the utility model is made up of deck 1, lower cover 2, tuningout seat 3, packing 4, middle segmentum intercalaris 5, two stage sealing device 6, blowout prevention box 7, blowout hookup 8, primary seal device 9, packing box 10, upper press cover 12.Its structure assembled relation is as follows: deck 1 top inner headed face and the tuningout seat 3 bottom peripheries that sealing ring is housed on it suit that matches, its external application lower cover 2 are tightened with screw thread, and tuningout seat 3 top inner headed face round platforms are to be equipped with packing 4 in the epicoele; Tuningout seat 3 top peripheries are connected with the middle segmentum intercalaris 5 of screw thread with its top, and the two stage sealing device 6 of middle segmentum intercalaris 5 and top thereof, blowout prevention box 7 and primary seal device 9 be welding mutually successively, and blowout prevention box 7 one sides between the two-stage sealing device are equipped with blowout hookup 8; In the packing box 10 of primary seal device 9 tops packing 11 is housed, upper press cover 12 is equipped with in the upper end.Wherein primary seal device 9, two stage sealing device 6 physical dimensions are identical, form by end covers at two sides 13 and the spring 15, jacking block 16, sealing block 18, positioning bolt 19 and the connecting bolts 20 that are arranged in the housing 17, left and right sides symmetry, sealing block 18 usefulness rubber are made.Blowout hookup 8 is by housing 21 and place spring 22, ball seat 23 and steel ball 24 in it to form.
