Abstract
The utility model relates to a continuous oil pipe used self-rotating spray head. The common rotating spray head mainly adopts a damping fluid for limiting speed, the structure is complex, and the seal is difficult. The continuous oil pipe used self-rotating spray head consists of a center tube, an outer barrel, a rolling bearing, a sliding sleeve, a nozzle rotating shaft, a friction block and a locking nut. The spray head is rotated by an eccentric nozzle; the friction block limits the speed; a hollow cavity is enclosed by the center tube and the outer barrel; the rolling bearing is mounted in the hollow cavity; the nozzle rotating shaft is mounted between the outside of the sliding sleeve and the outer barrel; the nozzle rotating shaft is provided with a thin and narrow upper part and a broad and thick lower part; and the locking nut locks the sliding sleeve and the nozzle rotating shaft in the hollow cavity enclosed by the center tube and the outer barrel. The friction block is a split-type block with two parts mounted in the outer barrel. After a liquid is fed into the spray head, the axial jet of a front nozzle spalls the sand bed at the front end, and an oblique impact nozzle generates turning pair to rotate the spray head and stir the settled sand, thereby facilitating rushing out of the sand. The self-rotating spray head has the advantages of simple structure, small size and light weight, and can effectively spall the sand bed and float the settled sand to be brought out of the ground.
Description
Technical field
The utility model relates to a kind of coiled tubing spinning shower nozzle, is mainly used in sand washing, scale removal and the cleaning of oil well, belongs to the wellbore tool in the petroleum recovering machinery.
Background technology
The shower nozzle that coiled tubing is commonly used has single injector and a plurality of nozzles at present, and fixed sprinkler is arranged, and rotating sprinkler is also arranged, but rotary nozzle often adopts the damping fluid speed limit, complex structure, and sealing difficulty is big.
The utility model content
The purpose of this utility model is to provide a kind of coiled tubing spinning shower nozzle, and this shower nozzle adopts eccentric nozzle that shower nozzle is rotated, and realizes speed limit by the brake pad speed limiting mechanism, and is simple in structure, good seal performance.
The utility model adopts following technical scheme, it is a kind of coiled tubing spinning shower nozzle, by central tube, urceolus, rolling bearing, sliding sleeve, the nozzle rotating shaft, brake pad and lock nut constitute, it is characterized in that central tube top has the pipe shoulder, urceolus is by being bolted to the pipe shoulder bottom of central tube, central tube and urceolus surround cavity, the central tube at cavity top is set with rolling bearing outward, on the central tube outer wall in the cavity sliding sleeve is housed, sliding sleeve is spacing by the rolling bearing bottom surface, outside the sliding sleeve and between the urceolus heterotypic spray nozzle rotating shaft is housed in the cavity, this heterotypic spray nozzle rotating shaft top is carefully narrow, in the cavity in the urceolus between thin narrow part in heterotypic spray nozzle rotating shaft top and urceolus brake pad is housed, the bottom of the heterotypic spray nozzle rotating shaft that urceolus bottom sliding sleeve is outer is broad and rough, heterotypic spray nozzle bottom outer diameter is identical with the outer diameter of urceolus, the lower surface of urceolus is spacing to the top of the broad and rough part in heterotypic spray nozzle bottom, central tube, have the spray orifice of connection between the capacitor of the broad and rough part of sliding sleeve and heterotypic spray nozzle rotating shaft bottom, lock nut is with sliding sleeve and the nozzle rotating shaft is locked at central tube and urceolus surrounds in the cavity.
Coiled tubing of the present utility model spinning shower nozzle, its brake pad are split type, and shared 2, in addition, its nozzle rotating shaft top cooperates with the brake pad profile, is installed in the urceolus.
The utility model operating principle, after liquid is squeezed into coiled tubing usefulness spinning shower nozzle, enter front nozzle 10 and oblique impact nozzle 11 by central tube, the axial jet of front nozzle is used to smash the casting bed of front end, oblique impact nozzle and nozzle shaft are to being not unison angle, be responsible for producing turning pair drive shower nozzle and rotate, the sand that will be deposited on net horizontal section simultaneously stirs, and is convenient to going out of sand.Damper adopts the rotating speed of the method control shower nozzle of friction catch, and rotating speed is high more, and the centrifugal force of brake pad is big more, and the frictional force of brake pad and urceolus is also big more, thereby realizes the purpose of control rotating speed.
The utility model coiled tubing is simple with the spinning nozzle structure, size is little, in light weight, can effectively smash casting bed, and sand setting is floated, help taking sand setting out of ground.
