Abstract
The utility model discloses an instrument of rightting that vibrates that hinders falls in horizontal well abrasionproof, including two female gyro wheel centralizer sleeves, the centralizer gyro wheel, the centralizer roller shaft, the hydraulic motor, go up footstep bearing, the axle takes place for eccentric excitation, lower footstep bearing, two male joints, produce eccentric power through the eccentric excitation rotation of axes of hydraulic motor drive, thereby this instrument and the drilling string that links to each other produce periodic vibration under the effect of off -centre power, make between the drilling string and the wall of a well pressure because of the vibration periodic reduction, make the static friction between the drilling string and the wall of a well become the dynamic friction, thereby make axial stiction become dynamic friction power, showing and reducing rubbing of drilling string and hinder and the moment of torsion, thereby it drags the pressure and glues smooth vibration because of what the friction produced to reduce the drilling string, mechanical drilling speed has been improved.
Description
Technical field
The utility model relates to oil, gas drilling field of tool, particularly relates to a kind of horizontal well abrasionproof and falls resistance vibration centralizing tool.
Background technology
At high angle hole, in horizontal well and extended horizontal well drilling process, the drill string of large gradient section and horizontal segment is because Action of Gravity Field causes, the drill string of non-perpendicular section leans against on the borehole wall, non-perpendicular section longer drill string weight is wherein larger, the frictional force producing between drill string and the borehole wall is larger, thereby the frictional resistance of drill string and moment of torsion are larger, cause the pressure of the drill and moment of torsion to be applied to fully and on drill bit, produce backing pressure and stick-slip vibration, backing pressure can cause drilling speed to reduce, stick-slip vibration can cause the pendulum angle of drill bit excessive because of the abrupt release of moment of torsion, cause the too early damage of drill bit, more likely cause the generation of down hole problem.
Summary of the invention
The utility model object is to reduce the frictional force of non-perpendicular section of drill string, reduce because friction causes backing pressure and stick-slip and vibrate, thereby improve rate of penetration and ensure drilling safety, use this instrument can greatly reduce non-perpendicular section of the pressure of the drill because of frictional resistance loss of drill string, therefore this instrument can meet in horizontal well and extended horizontal well drilling process the pressure of the drill because of friction loss in tolerance interval.
The technical solution of the utility model is as follows:
The utility model provides horizontal well abrasionproof to fall resistance vibration centralizing tool, this instrument comprises: two female rolling wheel centralizer sleeves 1, centralizer roller 2, centralizer roller shaft 3, fluid-power motor 4, upper thrust bearing 5, eccentricity excitation generation axle 6, lower thrust bearing 7, two male joints 8, described two female rolling wheel centralizer sleeve 1, the two male joints 8 in bottom of eccentricity excitation generation axle 6 and lower end are hollow setting, instrument hollow diameters can ensure that drilling well arrives shaft bottom smoothly, and can not produce creeping into influential pressure drop, it is characterized in that, this instrument comprises erection device, fluid-power motor and eccentricity excitation generation axle, wherein: fluid-power motor 4 is between the two male joints in the bottom of two female rolling wheel centralizer sleeves and lower end, for the rotary power of eccentricity excitation generation axle is provided, eccentricity excitation generation axle is connected by universal drive shaft with fluid-power motor, eccentricity excitation generation axle is by upper thrust bearing 5, lower thrust bearing 7 is installed in the cavity of two female rolling wheel centralizer lower cartridge, its fluid-power motor drives the two female rolling wheel centralizer sleeve inward turnings of eccentricity excitation generation axle to change the line of production and gives birth to periodic exciting eccentric force, eccentricity excitation generation axle one end connecting fluid force motor, the concentric segments of the other end extends in the two male joints in bottom, support effect and the axial location effect to eccentricity excitation generation axle and lower straight thrust bearing played in simultaneously two male joints. tool interior adopts hollow setting, and the drilling fluid pressure drop that tool bore produces can not exert an influence to drilling fluid in the effect in drilling process.
Brief description of the drawings
Fig. 1 is that resistance vibration centralizing tool structural representation falls in horizontal well abrasionproof of the present utility model; Fig. 2 is that horizontal well abrasionproof of the present utility model falls resistance vibration centralizing tool A to cutaway view; Fig. 3 is that horizontal well abrasionproof of the present utility model falls resistance vibration centralizing tool B to cutaway view; Wherein: two female rolling wheel centralizer sleeves 1, centralizer roller 2, centralizer roller shaft 3, fluid-power motor 4, upper thrust bearing 5, eccentricity excitation generation axle 6, lower thrust bearing 7, two male joint 8.
Detailed description of the invention:
Resistance vibration centralizing tool falls in the horizontal well abrasionproof that the utility model provides, drive 6 rotations of eccentricity excitation axle to produce eccentric force by fluid-power motor 4, thereby this instrument and the drill string that is connected produce periodically vibration under the effect of eccentric force, pressure between drill string and the borehole wall is periodically reduced because of vibration, make the static friction between drill string and the borehole wall become dynamic friction, thereby make axial static frictional force become kinetic force of friction, significantly reduce frictional resistance and the moment of torsion of drill string, thereby reduce backing pressure and stick-slip vibration that drill string produces because of friction, reduce the pressure of the drill loss causing because of frictional resistance, thereby raising rate of penetration, drill string passes in the middle of idler wheel centralizing 1 simultaneously, reduce the contact area of drill string and the borehole wall, reduce the friction of drill string and the borehole wall, that has played abrasionproof prevents the effect of mule foot a bit to neutralization, improve the service efficiency of drill bit. this tool body length is reasonable, and eccentricity excitation part is not used any seal and rubber parts, has ensured reliability and the service life of instrument.
