Description
Technical field:
The utility model relates to a kind of oil field window sidetracking technical field of operation, particularly a kind of slips inserted link one lead oblique window opening tool.
Background technology:
At present, in petroleum well workover operation, when oblique window sidetracking is led in use, lead oblique instrument many employings slips anchoring, the position of thus leading oblique instrument need be selected at the intact position of sleeve pipe, then can not use to lead tiltedly window for casing failure or perforated interval.
Utility model content:
The technical problems to be solved in the utility model be to provide a kind of slips inserted link one lead oblique window opening tool, the arrangement achieves and the position of window can be selected in the optional position of sleeve pipe, break the present situation that side-drilling windowing the window's position can only be confined to the intact position of sleeve pipe, make position satisfied exploitation and well workover requirement to greatest extent of windowing.Overcome the deficiency that existing position of windowing can only be selected at the intact position of sleeve pipe.
Technical solution adopted in the utility model is: a kind of slips inserted link one lead oblique window opening tool, comprise top connection, send into pipe assembly, steel ball I, cover plate, lead italic and steel ball II, top connection lower end connects sends into pipe assembly, leading italic is fixed on feeding pipe assembly by hold-down screw, send into pipe assembly lower end and connect ball seat, ball seat sidewall connects swivel tee, the side of swivel tee is logical to be inserted in tap and to be sealed by sealing ring II, tap is arranged on leads in italic, lead in italic and connect cover plate, send into pipe assembly and pass through ball seat, swivel tee, tap is connected with the inner flow passage of leading italic, lead italic lower end, upper fluid cylinder, lower fluid cylinder, lower end joint, inserted link connects in turn, inserted link has opening, pressure tube upper end is connected to leads in the inner flow passage of italic, pressure tube lower end is inserted in the center flow channels of upper cone, between upper cone and upper fluid cylinder, lock dog is installed, upper cone is connected by screw upper slips, upper slips can stretch out fluid cylinder, in lower fluid cylinder, lower cone is installed, adapter sleeve is provided with between upper cone and lower cone, bar of blocking is welded in adapter sleeve, between lower cone and lower fluid cylinder, lock dog is installed, lower cone is connected by screw lower slips, lower slips can stretch out lower fluid cylinder, lower cone inwall is connected by shear pin and shears ball seat.
The beneficial effects of the utility model are: the utility model is owing to have employed the mode of slips and the dual grappling of inserted link, thus having can the effect of the position of window selection in the optional position of sleeve pipe, break the present situation that side-drilling windowing the window's position can only be confined to the intact position of sleeve pipe, make position satisfied exploitation and well workover requirement to greatest extent of windowing.
Accompanying drawing illustrates:
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Fig. 1 is overall schematic of the present utility model.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is bottom of the present utility model enlarged diagram.
Detailed description of the invention:
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of slips inserted link one lead oblique window opening tool, comprise top connection 1, send into pipe assembly 2, steel ball I 10, cover plate 11, lead italic 12 and steel ball II 24, top connection 1 lower end connects sends into pipe assembly 2, leading italic 12 is fixed on feeding pipe assembly 2 by hold-down screw 3, send into pipe assembly 2 lower end connect ball seat 5 and sealed by sealing ring I 4, ball seat 5 sidewall connects swivel tee 8 and is sealed by sealing ring III 9, the side of swivel tee 8 is logical to be inserted in tap 6 and to be sealed by sealing ring II 7, tap 6 is arranged on leads in italic 12, lead in italic 12 and connect cover plate 11, send into pipe assembly 2 by ball seat 5, swivel tee 8, tap 6 is connected with the inner flow passage of leading italic 12, lead italic 12 lower end, upper fluid cylinder 15, lower fluid cylinder 27, lower end joint 28, inserted link 31 connects in turn, inserted link 31 has opening, pressure tube 14 upper end be connected to lead italic 12 inner flow passage in and sealed by sealing ring IV 13, the center flow channels that upper cone 20 is inserted in pressure tube 14 lower end is interior also by sealing ring V 19 sealing, lock dog 18 is installed between upper cone 20 and upper fluid cylinder 15, sealed by sealing ring VI 21 between upper cone 20 and upper fluid cylinder 15, upper cone 20 connects upper slips 16 by screw 17, upper slips 16 can stretch out fluid cylinder 15, in lower fluid cylinder 27, lower cone 25 is installed, adapter sleeve 23 is provided with between upper cone 20 and lower cone 25, bar 22 of blocking is welded in adapter sleeve 23, between lower cone 25 and lower fluid cylinder 27, lock dog 18 is installed, lower cone 25 connects lower slips 26 by screw 17, lower slips 26 can stretch out lower fluid cylinder 27, lower cone 25 inwall is connected by shear pin 30 and shears ball seat 29.
Go into the well after the utility model and drilling tool connect to design attitude, turn on pump adds hydraulic pressure, and hydraulic pressure arrives the utility model through drilling tool.Hydraulic drive upper cone 20 moves, promotes lower cone 25 and move down, upper cone 20 and lower cone 25 promote upper slips 16 respectively and lower slips 26 generation moves radially and is anchored on sleeve pipe, and lock dog 18 locks grappling.Continue to increase pump pressure and cut off shear pin 30, shear ball seat 29 and move down, now pump pressure bust is zero, and liquid, by inserted link 31 returns, forms circulation canal.Workover fluid is by drilling tool and the utility model return to ground.
Hydraulic Anchorage is used, without the need to cementing when sleeve pipe is intact.Inserted link 31 cementing grappling is used when casing failure.During cementing, between the utility model and sleeve pipe, annular space place sends into cement paste, rotates forward drilling tool and cuts off hold-down screw 3, send into pipe assembly 2 to be separated, instrument is slipped out of the hand, and circulation workover fluid washes out superfluous water mud, trip out feeding part, inserted link 31 grappling after cement slurry sets, carries out lower step construction.
Be understandable that, above about specific descriptions of the present utility model, the technical scheme described by the utility model embodiment is only not limited to for illustration of the utility model, those of ordinary skill in the art is to be understood that, still can modify to the utility model or equivalent replacement, to reach identical technique effect; Needs are used, all within protection domain of the present utility model as long as meet.
