Abstract
The utility model relates to the technical field of horizontal well coiled tubing sidetracking, in particular to a full hydraulic coiled tubing whipstock, wherein a locking piece of the device is embedded between a lock ring and a feed-in tube; an unlocking ring sleeves the lock ring and blocks the locking piece; the unlocking ring is connected to the inner wall of an oblique surface through a shear pin I; the lower end of the lock ring is in screwed connection with a seal ring; the lower end of the oblique surface is connected with a connecting body; the inner wall of the lower end of the connecting body is connected with a mandrel I; the lower end of the mandrel I is connected with a mandrel II; the outer wall of the lower end of the connecting body is connected with an outer cylinder; two pistons sleeve both the mandrel I and the mandrel II respectively; a retaining ring and a standby cap are mounted at the outer end of each piston; an upper clamp tooth and a lower clamp tooth are connected with the upper and lower pistons through shear pins II respectively; the upper clamp tooth and the lower clamp tooth are exposed out of a passage on the side wall of the outer cylinder; the lower end of the outer cylinder is connected with a guide shoe. By utilizing the full hydraulic coiled tubing whipstock, setting and releasing can be realized by only pumping and cycling drilling fluid to build up pressure without the need of ball throwing and rotating. The full hydraulic coiled tubing whipstock overcomes the deficiencies that the present coiled tubing sidetracking and windowing can't achieve rotating, ball throwing and releasing.
Description
Technical field:
The utility model relates to a kind of continuous-tube sidetrack horizontal well technical field, particularly a kind of full hydraulic continuous-tube whipstock.
Background technology:
Sidetrack horizontal well is the novel oil exploitation technology growing up on sidetracked hole, horizontal well basis, for original oil zone enhancing efficiency by relying on tapping internal latent power provides a highly effective approach, become in recent years domestic each oil field and closed down that well reproduces and oil reservoir is taped the latent power, improve one of ripe important technical of the rate of oil and gas recovery.
Conventional sidetracked hole is windowed, the mode that after whipstock adopts pitching to build the pressure more, rotation is put aside; And continuous-tube sidetracked hole is windowed, because continuous-tube can not rotate, so can not apply rotational release mode; Again due to the built-in cable of continuous-tube, can not pitching, so can not apply the pitching mode of giving up.
Utility model content:
The technical problems to be solved in the utility model is to provide a kind of full hydraulic continuous-tube whipstock, and this device has been realized without pitching and rotation, only needs turn on pump circulating fluid to build the pressure and just can realize setting and give up.Overcome the deficiency that existing continuous-tube sidetracked hole is windowed and can not be rotated and can not pitching give up.
Technical solution adopted in the utility model is: a kind of full hydraulic continuous-tube whipstock, and comprise and send into pipe, connector, urceolus, inclined-plane and joint, send into pipe and insert in inclined-plane, send into pipe upper end jointing, lock dog is embedded in locking ring and sends in pipe, release ring set is contained on locking ring and blocks lock dog, separating lock ring is connected on inclined-plane inwall by shear pin I, locking ring lower end screwed connection joint ring, lower end, inclined-plane connects connector, connector lower end inwall connects axle I, axle I lower end connects axle II, connector lower end outer wall connects urceolus, in axle I and axle II, be all set with a piston, piston outer end is provided with retaining ring and standby cap, upper card tooth and lower card tooth are connected on upper lower piston by shear pin II, upper card tooth and the passage of lower card tooth from outer tube side wall expose, urceolus lower end connects guide shoe.
The beneficial effects of the utility model are: the utility model, without pitching and rotation, only needs turn on pump circulating fluid to build the pressure and just can realize setting and give up, easy to operate, safe and reliable.
Accompanying drawing explanation:
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
As shown in Figure 1, a kind of full hydraulic continuous-tube whipstock, comprises and sends into pipe 1, connector 7, urceolus 8, inclined-plane 18 and joint 19, sends into pipe 1 and inserts in inclined-plane 18, sends into pipe 1 upper end jointing 19, lock dog 3 is embedded in locking ring 4 and sends in pipe 1, separating lock ring 2 is sleeved on locking ring 4 and blocks lock dog 3, separating lock ring 2 is connected on inclined-plane 18 inwalls by shear pin I 6, locking ring 4 lower end screwed connection joint rings 5, 18 lower ends, inclined-plane connect connector 7, connector 7 lower end inwalls connect axle I 12, axle I 12 lower ends connect axle II 13, connector 7 lower end outer walls connect urceolus 8, in axle I 12 and axle II 13, be all set with a piston 9, piston 9 outer ends are provided with retaining ring 14 and standby cap 15, upper card tooth 10 and lower card tooth 11 are connected on upper lower piston 9 by shear pin II 17, upper card tooth 10 and the passage of lower card tooth 11 from urceolus 8 sidewalls expose, urceolus 8 lower ends connect guide shoe 16.
The utility model is divided into two parts: the one, and setting part, card tooth relies on shear pin II 17 to be fixed on piston 9, when piston 9 is subject to thrust, shear pin II 17 is cut off, and push card tooth distending, blocks internal surface of sleeve pipe, realizes setting; The 2nd, the part of giving up, sends into pipe 1 and fixed by lock dog 3, and lock dog 3 is embedded in locking ring 4, and the outer release ring 2 that is with of locking ring 4, relies on shear pin I 6 to be fixed on inclined-plane 18.
During site operation, by continuous-tube, this instrument is lowered to the assigned address of down-hole, turn on pump circulating fluid builds the pressure, and when pump pressure reaches about 12Mpa, shear pin II 17 is cut off, and promotes piston 9 motions, makes card tooth distending, realizes setting; Continue to build the pressure, when pump pressure reaches about 20Mpa, shear pin I 6 is cut off, and promotes to separate lock ring 2 and moves downward, and lock dog 4 is discharged, and realization is given up, thereby extract, sends into pipe 1.
Be understandable that, above about specific descriptions of the present utility model, only for being described, the utility model is not limited to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can modify or be equal to replacement the utility model, to reach identical technique effect; As long as meet, use needs, all within protection domain of the present utility model.
