Abstract
The utility model relates to a multifunctional blowout control box blowout preventer for sealing rod pump wellhead in the field of oil producing oilfield, mainly solving the problems that current packing boxes are seriously abraded when a polish rod is not concentric with the wellhead, resulting in eccentric abrasion of the polish rod and reduced service life of the packing box. The blowout preventer comprises a packing barrel connected with a packing barrel cap, and an eccentricity adjusting ball seat connected with a blowout preventer, wherein the packing barrel is internally provided with a spiral packing; an upper pressing cover and a lower pressing cover are respectively arranged at the upper end and the lower end of the spiral packing; a polish rod passes through a central hole of the blowout preventer; the lower pressing cover is connected with a ball rod body which passes through a hole at the lower end of the packing barrel; the lower part of the ball rod body is spherical, and is in rotating fit with the eccentricity adjusting ball seat with a spherical internal surface and a ball cap; a valve seat sleeve communicated with the internal chamber of the eccentricity adjusting ball seat is fixed on the sidewall of the eccentricity adjusting ball seat; and a movable blowout preventing ball and a valve seat are arranged in the valve seat sleeve; a spring is arranged in the valve seat; and the difference between the diameter of the blowout preventing ball and the small aperture of the eccentricity adjusting ball seat is a positive value. The blowout preventer can automatically adjust the eccentricity, so that the polish rod can be concentric with the wellhead, so the polish rod can be prevented from being eccentrically abraded, and the blowout prevention function is achieved; and liquid in the well can be prevented from spraying out of the wellhead when the polish rod is separated, and the packing is simple and convenient to arrange.
Description
Technical field
The utility model relates to the used packing box of sucker rod pumping well head in the oil recovery field, oil field, a kind of specifically blowout prevention, automatic aligning and the quick multi-functional blowout prevention box blowout preventer of changing packing.
Background technology
In the sucker rod pumping process, reveal from well head in order to prevent crude oil, mechanical dynamic seal formula packing box is housed at the well head place, realize sealing to polished rod.Common packing box after well head installs, with the well head center line with regard to relative fixed, can't realize horizontal centering and inclination angle adjustment longitudinally.Owing to be difficult to guarantee theoretic concentric requirement when oil pumper suspension point, polished rod and well head are installed; The influence of the various destabilizing factors in back of in addition going into operation; All there is the situation of the suspension point and the well head disalignment of oil pumper polished rod eye in most of oil well, therefore has following problem: 1. because suspension point and well head center line misalign, will cause packing and polished rod generation eccentric wear; Along with the eccentric wear of packing makes the poorly sealed and leakage of oil of well head, also shorten the application life of packing; In case 2. the phenomenon of blowout owing to the effect of down-hole pressure, also can take place in the polished rod mill section of taking off, and causes serious environmental pollution, the wasting of resources and unnecessary workover treatment; 3. because dish with the box structural reason, when changing packing, shift out polished rod, old packing is plucked out, waste time and energy, influence the oil pumper actual effect.
Summary of the invention
In order to address the above problem, the utility model provides a kind of multi-functional blowout prevention box blowout preventer.This multi-functional blowout prevention box blowout preventer can horizontal, vertically be adjusted, and makes polished rod and well head concentric, avoids producing the eccentric wear phenomenon, has the blowout prevention function again, when preventing the polished rod section of taking off, and liquid ejection well head in the well, and it is quick and convenient to install packing additional.
The technical scheme of the utility model is: a kind of multi-functional blowout prevention box blowout preventer; Comprise packing tube that is connected with packing tube cap and the tuningout ball seat that is connected with blowout preventer, described packing tube is built-in with Screw disk-seal tube, and the upper and lower end of Screw disk-seal tube is equipped with upper press cover and lower cover respectively; Polished rod passes the centre bore of this multi-functional blowout prevention box blowout preventer; Wherein, described lower cover with pass the packing tube under the club body of stomidium be connected, the bottom of club body is spherical in shape and be rotatably assorted with tuningout ball seat and ball cap with spherical inside surface; The fixing valve seat cover that communicates with inner chamber on the sidewall of tuningout ball seat; The valve seat cover is built-in with movably spray-proof ball and valve seat, and valve seat is built-in with spring, and the small-bore of the diameter of spray-proof ball and tuningout ball seat difference on the occasion of.
The cervical fixation of said club body supports the cap of pulling of packing tube, pulls back-up wrench on the cap; The port of described valve seat cover is equipped with sealing mat and connects plug; Be equipped with sealing ring between the spherical of described tuningout ball seat and club body bottom.
The beneficial effect of the utility model is: owing to adopt technique scheme; The club end of packing tube lower end adopts spherical structure to cooperate with tuningout ball seat and ball cap; Have the automatic aligning function,, just can realize the center line centering of packing box and polished rod and well head automatically through effective cooperation of several parts; Avoid polished rod generation eccentric wear phenomenon, and prolong the application life of packing; By linking with spanner with the packing tube, can change fast exposing the packing that is sealed in polished rod, needn't shift out polished rod, directly packing is got final product on polished rod, simple to operation, do not influence the work actual effect of oil pumper; Owing in the ball cover cavity spray-proof ball is set, once polished rod comes off, the pressure in the tube upwards impacts spray-proof ball, makes its central hole that withstands on the tuningout ball seat in addition, prevents liquid ejection well head in the well, reduces contaminated environment.
