Utility model content:
The technical problems to be solved in the utility model be provide one kind can through integration window opening tool, this device realize A time brill windowing task, decreases windowing operation, reduces construction cost, and can after sidetracking construction terminates insertion original old Well, makes old well residue gas continue output, to greatest extent using the surplus value of old well, the built-in one-way flow valve of instrument, There is gas cut thus causing great work accident during preventing from opening a window and bore branch well hole.Overcome existing old street district level The windowing task of well technology needs many brills just to enable, and windowing operation is many, and working performance is low, the high deficiency of construction cost.
Technical solution adopted in the utility model is: one kind can through integration window opening tool, including milling cone, insertion Formula whipstock, fluid cylinder set, central canal and lower contact;Milling cone lower end is set with milling tapered sleeve and is fixed by shear pin, milling tapered sleeve Followed closely by lifting and be connected with through whipstock with being lifted to follow closely, through whipstock lower end inner wall passes through shear pin It is connected with sealing block, sealing block seals through whipstock central passage, the screwed connection of sealing block lower end has one-way flow valve, gold Belong to coil pipe one end and pass through joint with milling cone hydrophthalmia phase welding, the metal coil pipe other end passes through through whipstock side wall and unidirectional stream Port valve is connected, and metal coil pipe is embedded in through whipstock outer wall fluting, through whipstock lower end and fluid cylinder threading Connect, fluid cylinder pipe screwed connection on liquid inboard wall of cylinder liner, fluid cylinder pipe lower end and central canal screwed connection, piston is sleeved on fluid cylinder pipe On, piston is against inverted-proof ring and puts, anti-down ring set lower end and cone screwed connection, and cone is sleeved on central canal and passes through Shear pin is fixed, and inverted-proof ring is placed in cone lower end, and inverted-proof ring, slip spider, packing element are sequentially sleeved on central canal from top to bottom On, slip spider is fixed on central canal by shear pin, and slips is arranged in the groove between slip spider and cone, slips Baffle ring and slip spider screwed connection, on central canal lower end outer wall, ball seat is connected by shear pin for lower contact screwed connection On central canal lower end inner wall, metal ball is sitting on ball seat.
The beneficial effects of the utility model are: this utility model achieves a brill windowing task, decreases windowing operation, Reduce construction cost, and can after sidetracking construction terminates the original old well of insertion, make old well residue gas continue output, maximum The surplus value of the old well of utilization of limit, the built-in one-way flow valve of instrument, there is gas during preventing from opening a window and bore branch well hole Invade thus causing great work accident.
Brief description:
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
Fig. 1 is structural representation of the present utility model.
Specific embodiment:
As shown in figure 1, one kind can through integration window opening tool, include milling bore 1, through whipstock 8, fluid cylinder set 16th, central canal 23 and lower contact 25;Milling is bored 1 lower end and is set with milling tapered sleeve 3 and is fixed by shear pin 2, and milling tapered sleeve 3 passes through Lifting nail 6 is connected with through whipstock 8 with lifting nail 7, and through whipstock 8 lower end inner wall passes through shear pin 10 are connected with sealing block 9, and sealing block 9 seals through whipstock 8 central passage, and sealing block 9 lower end screwed connection has unidirectional stream Port valve 13, joint 4 is passed through with milling cone 1 hydrophthalmia phase welding in metal coil pipe 5 one end, and metal coil pipe 5 other end passes through through deflecting Device 8 side wall is connected with one-way flow valve 13, and metal coil pipe 5 is embedded in through whipstock 8 outer wall fluting, through deflecting Device 8 lower end and fluid cylinder cover 16 screwed connections, and fluid cylinder pipe 18 screwed connection covers on 16 inwalls in fluid cylinder, fluid cylinder pipe 18 lower end and center Pipe 23 screwed connection, piston 21 is sleeved on fluid cylinder pipe 18, and piston 21 lower end is against on anti-down ring set 22, anti-down ring set 22 lower end With cone 27 screwed connection, cone 27 is sleeved on central canal 23 and fixing by shear pin 11, and inverted-proof ring 26 is placed in cone Body 27 lower end, inverted-proof ring 26, slip spider 17, packing element 20 are sequentially sleeved on central canal 23 from top to bottom, and slip spider 17 passes through to cut Cut pin 15 to be fixed on central canal 23, slips 12 is arranged in the groove between slip spider 17 and cone 27, slips baffle ring 19 with slip spider 17 screwed connection, lower contact 25 screwed connection on central canal 23 lower end outer wall, ball seat 28 pass through shear pin 24 are connected on central canal 23 lower end inner wall, and metal ball 14 is sitting on ball seat 28.
This utility model is implemented to be generally divided into two steps:
The first step: instrument grappling and windowing task
This utility model is gone into the well with drill string after specified windowing depth, and turn on pump is suppressed to certain value, and shear pin 11 is cut Disconnected, cone 27 is descending under the promotion of piston 21, and slips 12 opens, after slips 12 complete grappling in sleeve pipe, shear pin 15 cut off, and packing element 20 starts annular space in expanding sealing sleeve pipe, and hydraulic pressure persistently increases, when pressure reaches maximum, shear pin 24 cut off, and ball seat 28 and metal ball 14 drop in lower contact 25, and this utility model Hydraulic Anchorage action in sleeve pipe completes.Under One step pushes drill string, and shear pin 2 is cut off, and milling cone 1 is separated with milling tapered sleeve 3, so far, spuds in and just can carry out window sidetracking operation.
Second step: the old well of insertion
After branch well hole finishing drilling, under enter supporting flush pipe, turn on pump, through whipstock 8 intraclast is rinsed well, then Push flush pipe, cut off shear pin 10, sealing block 9 drops on fluid cylinder pipe 18, through whipstock 8 central passage is beaten Open, old well air ventilation passage is opened.
It is understood that above with respect to specific descriptions of the present utility model, be merely to illustrate this utility model and not It is limited to the technical scheme described by this utility model embodiment, it will be understood by those within the art that, still permissible This utility model is modified or equivalent, to reach identical technique effect;As long as meeting and using needs, all in this reality Within new protection domain.
