Brief description
Fig. 1 is structural representation of the present utility model.
Fig. 2 is partial enlarged drawing of the present utility model.
Specific embodiment
With reference to the accompanying drawings structural principle of the present utility model and operation principle are described further.
With reference to shown in Fig. 1: sands-proof check oil drainage type oil tube anchor device, including central canal 10, the upper part set of central canal 10
Have a piston 3, the tube wall of central canal 10 on piston 3 right side be provided with the oilhole mouth 22 with sand control screens, central canal 10 upper end with upper
Joint 1 connects, and top connection 1 is locked with piston 3；It is cased with slip sleeve 11, the left end step of slip sleeve 11 connects in the middle part of central canal 10
The cone step of upper vertebral body 9, the spline step of upper vertebral body 9 is connected with the spline step of piston 3, sets on rear side of the inner chamber of upper vertebral body 9
It is equipped with lock ring 8 and covers 6 with lock ring, lock ring 8 is placed on central canal 10 with lock ring set 6；Slip sleeve 11 right-hand member connects the cone of hypocentrum 14
Face, the afterbody of hypocentrum 14 is connected with draining set 16, is provided with closing piece 17 in draining set 16；The lower end of central canal 10 is passed through to connect
19 are connected with lower contact 21.
Rectangle slip groove 23 is provided with described slip sleeve 11, in slip groove 23, is provided with slips 13, slips 13 with
It is provided with flat spring 12, slips 13 is placed on central canal 10 between slip sleeve 11.
The surrounding of described draining set 16 is provided with oil leak hole.
It is provided with sealing ring 1 between described piston 3 and top connection 1.
It is provided with sealing ring 25 between described central canal 10 and piston 3.
It is provided with sealing ring 3 18 between described central canal 10 and lower contact 21.

The spline step of described upper vertebral body 9 is connected by screw 7 with the spline step of piston 3.
Described union joint 19 passes through deblocking pin 20 with lower contact 21 and is connected.
Operation principle of the present utility model is:
The anchoring process of sands-proof check oil drainage type oil tube anchor device:
Sands-proof check oil drainage type oil tube anchor device is connected on down-hole pump, down to design well depth, in well head high pressure pump liquid
In the presence of body pressure, the band sand control screens oilhole 22 through central canal 10 for the hydraulic pressure, plays filtration fine sand, the effect of deposit, prevents
The abrasion of each part of anchor.Hydraulic action, on piston 3, when hydraulic pressure is more than and sets pressure, sets pin 2 and is cut off, live
Plug 3 promotes upper cone 9 descending, slips 13 is strutted and is anchored on sleeve pipe, and piston 3 also promotes lock ring set 6 to make under lock ring 8 simultaneously
OK, retaining mechanism stepping locking in anchoring process, can prevent slips 13 resilience.Now, even if releasing the hydraulic pressure in oil pipe, slips
13 are also in anchoring states all the time, isolate sand grains simultaneously, prevent sand card.
The deblocking of sands-proof check oil drainage type oil tube anchor device and draining process:
Because lower contact 21 is connected also motionless with compression pump, deblocking is cut off in therefore top connection 1, central canal 10 and lower contact 21
Pin 20, hydraulic action pushing mechanism is up, when the closing piece 17 that central canal 10 is connected with lower contact 21 is up to drain pan, closing piece
17 supports losing draining set 16, in the presence of fluid power in tail pipe weight and oil pipe, lower contact 21 is separated with central canal 10,
Drain path is opened, and realizes draining and drives lower cone 14 to move down, and central canal 10 drives upper cone 9 to move up simultaneously,
Slips 13 loses upper cone 9 and the effect of lower cone 14, departs from sleeve pipe under flat spring 12 effect.At lower contact 21 and center
During pipe 10 separates, the sealing ring 18 between lower contact 21 and central canal 10 is destroyed.Progressively going up with down-hole string
Carry and reclaim, the crude oil in oil pipe also progressively lets out down-hole, therefore will not pollute in well head.
