The specific embodiment
With reference to accompanying drawing 1, the automatic well straightening drilling tool of a kind of pendulum hydraulic type, it comprises upper support seat 1; Pod apertures 2; Upper sphere 3; Arc 4; Swing arm 5; Pendulum 6; Slideway 7; Lower sphere 8; Swing arm 9; Ball valve 10; Lower support seat 11; Arc 12; Liquid flow hole 13; Annular groove 14; Piston 15; Piston baffle 16; Piston rod 17; Spring 18; Pressure relief vent 19; Piston inlet 20; Housing 21.Housing 21 is the cylinder type hollow joint, upper support seat 1 is fixed in the housing 21, on upper support seat 1, be processed with three pod apertures 2 that shape is identical, be processed with semicircle ball chamber at upper support seat 1 center downside, upper sphere 3 is put into semicircle ball chamber, two arcs 4 place the ball chamber from the below of upper support seat 1 with upper sphere 3, and upper support seat 1 and arc 4 form a ball chamber.Pendulum 6 connects and composes a pendulum with upper sphere 3 by swing arm 5 for the spheroid of fluting, pendulum 6, and 21 of pendulum and housings form annular fluid passage; With pendulum 6 diameters is that axle center fluting forms slideway 7, and lower sphere 8 is packed in the slideway 7, and lower sphere 8 cooperates with pendulum 6 above it, and gives and stay the swing arm gap.Be connected by swing arm 9 between lower sphere 8 and the ball valve 10; Lower support seat 11 is fixed in lower end in the housing 21, and lower support seat 11 is made up of two arcs 12, and arc 12 forms a spherical inner chamber, and ball valve 10 is installed wherein; Be processed with liquid flow hole 13 in ball valve 10 bottoms, be processed with an annular groove 14 by horizontal circumferencial direction on the ball valve 10, be processed with 6 holes perpendicular to ball valve 10 centre of sphere directions on annular groove, liquid flow hole 13 is connected with hole on the annular groove 14; Be processed with piston rod 17 on 21 times end housings of housing, piston 15 is installed in piston rod 17, piston baffle 16 is pressed on piston 15 in the piston rod 17 by spring 18, and piston baffle 16 is fixed on the housing 21, and the quantity of piston and piston rod is 3 covers; On piston rod 17, be processed with pressure relief vent 19; Along continuous straight runs is processed with piston inlet 20 on lower support seat 11, piston inlet 20 and piston rod 17 UNICOMs.Housing 21 upper/lower terminals are processed with screw thread and link with drilling tool.When borehole wall run-off the straight, pendulum 6 will be under the effect of himself gravity, be stabilized in the flash of the inclination borehole wall, drive ball valve 10 and tilt, at this moment, annular groove 14 communicates with piston inlet 20, drilling fluid enters annular groove 14 from liquid flow hole 13, enters piston inlet 20 by the runner in the lower support seat 11 again, and drilling fluid just begins to inject piston rod 17, make piston 15 when reaching flash of the borehole wall, produce enough big thrust.Leave pressure relief vent 19 in the piston rod 17, because pressure relief vent 19 diameters are less, drilling fluid can form bigger pressure through out-of-date in piston rod 17, push piston 15 to borehole wall flash, and the reaction force of the borehole wall makes drill bit increase at the sales volume of cutting on low limit.When annular groove on the ball valve 10 14 staggers with piston inlet 20, drilling liquid flow is closed to the passage of piston rod 17, in piston rod 17, can not form the pressure that driven plunger relies on the borehole wall, piston resets under the promotion of spring, and the drilling fluids in the piston rod 17 flow out through pressure relief vent 19, thus drill bit the cutting output with exterior domain can not increase on the low limit of the borehole wall, so move in circles, hole deviation is responded in good time, and reduces gradually, causes well to be tending towards vertical.
