Description
Technical field
The utility model relates to a kind of mechanical automatic vertical drilling tool.
Background technology
Conventional straight well Anti-inclining mainly is to bore soon with packed hole assembly weight to protect directly, hang up and beat well straightening with light pressure of pendulum assembly, its drawback is with low the pressure of the drill and expensively exchanges little hole deviation for, with hanging down drilling speed assurance wellbore quality, it has larger limitation, is difficult to generally promote.
The utility model content
The purpose of this utility model provides a kind of automatic vertical drilling tool exactly for addressing the above problem, and it can realize in the drilling process the in good time correction to hole deviation.
For achieving the above object, the utility model adopts following technical scheme:
A kind of automatic vertical drilling tool, it comprises housing, housing one end is connected with crossover sub, the other end is connected with drill string, is provided with lower moushroom valve in the shell ends inside that is connected with drill string, lower moushroom valve with housing with drill string rotating; That matches with crossover sub in housing is provided with flow guiding head, and flow guiding head is connected with axle one end; The axle other end is connected with upper moushroom valve, and upper moushroom valve cooperates with lower moushroom valve, is provided with eccentric runner at upper moushroom valve, and lower moushroom valve is provided with pod apertures, and the pod apertures of lower moushroom valve periodically staggers, is communicated with eccentric runner along with rotating; Also be provided with piston rod at housing and lower moushroom valve corresponding end, be provided with piston in it, be provided with relief hole at piston rod, the relief hole position cooperates with the pod apertures position, and lower moushroom valve pod apertures when rotating also periodically staggers, is communicated with relief hole; Be provided with vertically counterweight at the housing parts inwall.
Described eccentric runner is radial arrangement.
The utility model at work, if the well run-off the straight, counterweight will be stabilized in the low limit of inclined borehole under himself Action of Gravity Field, the fan-shaped eccentric runner of upper moushroom valve then is stabilized in the well flash.Drill string drives housing and the rotation of lower moushroom valve.When the eccentric runner of the radial arrangement on the upper moushroom valve when pod apertures on the lower moushroom valve overlaps, the passage that the inside and outside high-low pressure fluid of drill string is asked is opened, cleaner for high-pressure drilling fluid enters piston rod, pushing piston relies on the flash borehole wall, and the reaction force of the borehole wall is so that the cutting output increase of drill bit on the low end hole wall of well.Drill string drives housing and moushroom valve rotates so that the pod apertures on the lower moushroom valve and the fan-shaped eccentric runner on the upper moushroom valve stagger, passage between the inside and outside high-low pressure fluid of drill string is closed, cleaner for high-pressure drilling fluid can not driven plunger rely on the borehole wall, so drill bit can not increase in the cutting output of the low end hole wall of well with exterior domain.When drill string continues rotation, said process moves in circles, piston is by the pressure differential of the inside and outside formation of drill string, periodically rely on the flash borehole wall, drill bit is applied the periodicity lateral force of pointing to the low limit of well, increase the cutting output of drill bit on the low end hole wall of well, realize in the drilling process the in good time correction to hole deviation.
The beneficial effects of the utility model are: automatically respond to hole deviation and carry out the active well straightening when rotary drilling, thereby can effectively reduce the suffered frictional force of drill string and resistance, make the transmission of the pressure of the drill and moment of torsion more effective, also make formed well more smooth, be conducive to reduce the bit freezing risk.Importantly can discharge the pressure of the drill, normally creep into and improve drilling speed.
