The beneficial effect of the utility model is: the utility model has been owing to adopted the mode of positioned internal system, thereby has the function of positioning of rotating automatically, and directly orientation is lowered to whipstock and locatees, and has improved efficiency of construction.
Description of drawings:
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Accompanying drawing is the structural representation of the utility model.
The specific embodiment:
Shown in accompanying drawing, a kind of whipstock anchoring device of rotatable location comprises slip spider 1, slips 3, cone 4, packing element 6, parent tube 10 and top connection 22; Parent tube 10 outsides connect slips 3 through slip spider 1, and cone 4 places slips 3 upper ends and is connected on the parent tube 10 through pin, and cone 4 upper ends are provided with packing element baffle ring 5; Packing element baffle ring 5, packing element 6, power transmission outer tube 18 are sleeved on the parent tube 10 from bottom to up successively, and power transmission outer tube 18 upper ends connect piston 19, and fluid cylinder 21 is connected with piston 19 through piston pin 20; Fluid cylinder 21 upper ends are threaded with top connection 22 lower ends, and fluid cylinder 21 is sleeved on piston 19 and sends into pipe 17 outsides, and sending on the pipe 17 of piston 19 upper ends has pressure transmission hole; Send into pipe and contiguous block 9 is installed on 17, contiguous block 9 outsides are connected with parent tube 10 inner threads, send into piston 15 and are contained in and send into also support and connection pieces 9 of pipe 17 inboards; Send into piston 15 upper end outer walls and be provided with groove, send into pipe 17 corresponding piston 15 groove location of sending into and have pressure transmission hole, send into piston 15 inboards and be provided with ball seat 12; Send into piston 15 and can keep relative slip, send into piston 15 lower ends and be provided with and cut ring 8, cut ring 8 and manage 17 and be connected with sending into through ball seat pin 7 with ball seat 12; Ball seat 12 outer walls with cut ring and 8 be threaded; Send into pipe 17 lower end inwalls and be provided with baffle ring 2, positioning pipe 16 lower ends are threaded with location slip spider 14, and location slip spider 14 connects location slips 13; Location slips 13 connects parent tube 10 through grappling pin 11, and grappling pin 11 places in the circumferential chute of parent tube 10.
In Multilateral Wells is windowed process, be lowered to the utility model precalculated position in the well through drilling tool, 10Mpa is suppressed in pitching, under the promotion of power transmission outer tube 18, cuts off the cone pin, and packing element 6 expands, and slips 3 sets simultaneously, and the seat of implementation tool is hung; Continue to suppress 18Mpa, cut off ball seat pin 7, it is descending that piston 15 is sent in ball seat 12 drives, and contiguous block 9 is fallen in the groove of sending into piston 15, throws off with parent tube 10, accomplishes the action of giving up.Tubing string is sent in proposition, and the adjustment orientation is bored orientation with another time and is lowered to whipstock, and positioning pipe 16 automatic rotations align with whipstock and are connected; Press down 8 tons on drilling rod, cut off grappling pin 11, location slips 13 sets; The anchor tool navigation system realizes that orientation sets; Continue to be depressed into 16 tons, send into drilling rod and cut off, propose whipstock and send into drilling rod with the pin that is connected of whipstock.
