Abstract
The utility model relates to a radial hydraulic vibrator. The radial hydraulic vibrator comprises an upper switching short joint, a body, a lower switching short joint and a rotor arranged inside the body. A spiral structure is further arranged inside the body, the rotor is of an eccentric spiral structure, the lead of the rotor is matched with that of the spiral structure inside the body, and the two ends of the rotor are of a hollow flow passing structure. Flow passing holes are formed inside the upper switching short joint and the lower switching short joint. The rotor rotates eccentrically in the body under the action of liquid flow pressure, so that the body is driven to vibrate in the radial direction. Friction resistance between a drill stem and a well wall can be effectively reduced, and well drilling speed can be increased.
Description
Technical field
The utility model relates to the radially hydraulic vibrator of power tool, particularly one in water of oil-gas field horizontal well and directional well drilling construction.
Background technology
In petroleum drilling operation, particularly, in horizontal well and directional well drilling operation, horizontal segment and gradient section drill string frictional resistance are large, have a strong impact on normally exerting pressure of drill string, have hindered the lifting of bit speed.Therefore, solve horizontal segment and the slow problem of gradient section rate of penetration, just must reduce the frictional resistance between drill string and the borehole wall.Therefore on market, be badly in need of a kind of instrument that can effectively alleviate drill string frictional resistance, promote bit speed.
Summary of the invention
The utility model can provide a kind of radially hydraulic vibrator that effectively alleviates drill string frictional resistance, promotes bit speed.
The utility model is by adopting following technical proposals to realize:
One is hydraulic vibrator radially, comprises the top conversion pipe nipple, body, the bottom conversion pipe nipple that connect successively, and is arranged at the rotor of body interior, and described body interior is also provided with helical structure; Described rotor is eccentric helical structure, and its helical pitch coordinates with the helical structure helical pitch of body interior, and what two ends of rotor portion was hollow crosses flow structure; The inside of described top conversion pipe nipple and bottom conversion pipe nipple is provided with flowing hole.
Further, the two ends of top conversion pipe nipple and bottom conversion pipe nipple are provided with screw thread; The lower end that pipe nipple is changed in the upper end of described top conversion pipe nipple and bottom is screw threads of petroleum drilling tools, is connected with oil drilling tools; The lower end of described top conversion pipe nipple is connected with the threaded engagement at body two ends with the upper end of bottom conversion pipe nipple
Further, the helical structure of described body interior is rubber structure, and to cast form and the body engagement of glue.
Further, the internal diameter of described flowing hole is less than the external diameter of rotor, prevents rotor shifting.
Further, the upper end of described bottom conversion pipe nipple is provided with hard alloy surface, and described hard alloy surface is that plane coordinates with the flow structure excessively of rotor tip.After bottom conversion pipe nipple is connected with body, automatically forms and coordinate.
Brief description of the drawings
Below in conjunction with embodiment accompanying drawing, the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model device.
In figure: 1. top conversion pipe nipple 2. body 3. rotor 4. helical structure 5. bottom conversion pipe nipple 6. flowing hole 7. hard alloy surfaces
Detailed description of the invention
Radially hydraulic vibrator of one as shown in Figure 1, comprises the top conversion pipe nipple 1, body 2, the bottom conversion pipe nipple 5 that connect successively, and is arranged at the rotor 3 of body 2 inside, and described body 2 inside are also provided with helical structure 4; Described rotor 3 is eccentric helical structure, and its helical pitch coordinates with helical structure 4 helical pitches of body 2 inside, and what rotor 3 both ends were hollow crosses flow structure; The inside of described top conversion pipe nipple 1 and bottom conversion pipe nipple 5 is provided with flowing hole 6.The internal diameter of described flowing hole 6 is less than the external diameter of rotor, prevents rotor shifting.The helical structure 4 of body 2 inside is rubber structure, and to cast form and the body engagement of glue.
Upper and lower part conversion pipe nipple is connected with the form of screw thread with body, and the lower end that pipe nipple 5 is changed in the upper end of described top conversion pipe nipple 1 and bottom is screw threads of petroleum drilling tools, is connected with oil drilling tools; The lower end of described top conversion pipe nipple 1 is connected with the threaded engagement at body 2 two ends with the upper end of bottom conversion pipe nipple 5.The upper end of described bottom conversion pipe nipple 5 is provided with hard alloy surface 7, and described hard alloy surface 7 coordinates with the overcurrent structural plan of rotor 3 ends, and it,, after bottom conversion pipe nipple 5 is connected with body 3, automatically forms and coordinate.
Below the use procedure of the utility model device is illustrated:
In the time that current pass through body, the pressure of water makes rotor 3 in the interior generation eccentric rotary of body 2, in rotor 3 in the time there is eccentric rotary, have an effect with the helical structure 4 of body 2 inside, make whole radially hydraulic vibrator produce footpath vibration upwards, drive drill string to depart from the borehole wall, thereby play the frictional resistance reducing between drill string and the borehole wall, promote the effect of bit speed.
Finally it should be noted that: above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art should be appreciated that its technical scheme that still can record previous embodiment modifies, or part technical characterictic is wherein equal to replacement; And these amendments or replacement do not make the essence of appropriate technical solution depart from the spirit and scope of technical solutions of the utility model.
