The angular contact bearing is arranged between the shell and the swivel head. A well-flushing jet orifice and a swivel jet orifice are arranged at the lower end of the swivel head. According to the special design of a swivel jet runner, the swivel head has a spinning function, so that jet uniformity is guaranteed, and flushing effect is good. Besides, the spinning well-flushing nozzle is simple in structure and easy to detach and has few components. As the well flushing jet pressure is free of affection from spinning, high-pressure direct well flushing can be guaranteed.
Description
Technical field
The utility model relates to the Oil/gas Well cleaning means, particularly a kind of spinning well-flushing shower nozzle.
Background technology
The oil gas field well-flushing mostly is fixed with shower nozzle at present, and this structure exists rinses inhomogeneous, halfway problem, and rare several rotating sprinklers are complex structure mostly, and are not easy to assemble.Therefore, need the well-flushing shower nozzle that a kind of structure is relatively simple and can rotate.
Summary of the invention
The purpose of this utility model is to provide the spinning well-flushing shower nozzle that a kind of structure is relatively simple and can rotate.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of spinning well-flushing shower nozzle comprises connector, shell, swivel head and pair of horns contact ball bearing.Connector and shell are the stairstepping cylindrical structure, and swivel head is provided with cavity for inside and the upper end is penetrating, the stairstepping rotary structure of lower end sealing.The upper end of connector has been provided with the internal thread of connection function, matches by the internal thread of external screw thread with shell upper end setting in the lower end.The outer surface at two ends, swivel head up and down fits with the interior contoured surface of the interior contoured surface of connector lower end and shell lower end respectively.Angular contact ball bearing is arranged between shell and swivel head, and the outer surface of angular contact ball bearing outer ring matches with the interior contoured surface of shell, and the interior contoured surface of inner ring matches with the outer surface of swivel head.The lower end of swivel head is provided with well-flushing jet orifice and the rotary irradiating head piece that is positioned at the differing heights place.The well-flushing jet orifice is the through hole that runs through the swivel head sidewall, and the rotary irradiating head piece comprises connected entrance and go out head piece, and an end of connected entrance is connected with the internal cavities of swivel head, the other end with go out head piece and be connected, and the axis of connected entrance is parallel with the axis of well-flushing jet orifice.The axis that goes out head piece is all vertical with the axis of the axis of connected entrance and swivel head, and goes out head piece and be connected with the space outerpace of swivel head.
Swivel head is the rotary part of said apparatus, and its outer surface is supported on enclosure by the pair of horns contact ball bearing.The rotation of swivel head is to realize by flushing fluid and coordinating of rotary irradiating head piece.When the internal cavities when flushing fluid by connector enters the internal cavities of swivel head and arrives its bottom, part flushing fluid is the connected entrance by the rotary irradiating head piece and flowing out with the perpendicular head piece that goes out of connected entrance axis successively, thereby rotate moment of torsion, the rotation of driven rotary head.Meanwhile, a part of flushing fluid flows out by the well-flushing jet orifice in addition, and the borehole wall is cleaned.The rotary irradiating head piece is positioned at different height from the well-flushing jet orifice, and to avoid its jet disturbance each other, the jet orifice number can be selected according to the practice of construction needs.Connected entrance and the vertical design that goes out the head piece axis make rotation torque can reach larger value.Angular contact ball bearing between swivel head and shell has limited the radial and axial displacement between two parts, and the vibration of whole shower nozzle when effectively reducing jet is particularly suitable for coordinating the lower drilling rod uses of rigidity such as coiled tubing.
Preferably, on the contact surface of connector and shell, be respectively arranged with a plurality of sealing rings on the contact surface of connector and swivel head and on the contact surface of shell and swivel head.Sealing ring not only can be realized the sealing between each parts, can also play to the rotary speed of swivel head certain restriction.
Adopt spinning well-flushing shower nozzle of the present utility model, utilize the particular design of rotating jet runner, make swivel head have the function of automatic rotation, thereby guarantee that jet is even, developing result is good.In addition, this device overall structure is simple, and parts are few, easy to assemble, and the well-flushing jet pressure is not subjected to Effect of Rotation, can guarantee the HVDC well-flushing.
Description of drawings
Fig. 1 is the structural representation of the utility model spinning well-flushing shower nozzle.
Fig. 2 is that A-A in Fig. 1 is to sectional view.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Fig. 1 to 2,1 is connector, and 2 is shell, and 3 is swivel head, and 4 is angular contact ball bearing.Connector 1 and shell 2 are the stairstepping cylindrical structure, and swivel head 3 is provided with cavity for inside and the upper end is penetrating, the stairstepping rotary structure of lower end sealing.The upper end of connector 1 has been provided with the internal thread of connection function, and the lower end is by external screw thread and shell 2) internal thread that arranges of upper end matches.The interior contoured surface of the outer surface of swivel head 3 upper ends and connector 1 lower end fits, and the interior contoured surface of the outer surface of swivel head 3 lower ends and shell 2 lower ends fits.Angular contact ball bearing 4 is arranged between shell 2 and swivel head 3, and the outer surface of angular contact ball bearing 4 outer rings matches with the interior contoured surface of shell 2, and the interior contoured surface of angular contact ball bearing 4 inner rings matches with the outer surface of swivel head 3.The lower end of swivel head 3 is provided with well-flushing jet orifice 301 and the rotary irradiating head piece 302 that is positioned at the differing heights place.Well-flushing jet orifice 301 is for running through the through hole of swivel head 3 sidewalls, and rotary irradiating head piece 302 comprises connected entrance 303 and goes out head piece 304.One end of connected entrance 303 is connected with the internal cavities of swivel head 3, the other end with go out head piece 304 and be connected, and the axis of connected entrance 303 is parallel with the axis of well-flushing jet orifice 301.The axis that goes out head piece 304 is all vertical with the axis of the axis of connected entrance 303 and swivel head 3, and goes out head piece 304 and be connected with the space outerpace of swivel head 3.Be respectively arranged with a plurality of sealing rings 5 on the contact surface of connector 1 and shell 2, on the contact surface of connector 1 and swivel head 3 and on the contact surface of shell 2 and swivel head 3.
