Wherein, the wall of described central tube is provided with at least one vertical line umbilical and passes through hole, and middle part is provided with at least one pressure transmission hole.Described stop collar, lock sleeve, lock ring, spring and pressure cap form self-locking mechanism.Described cone 7 is fixed on central tube by safety pin.Described stop collar is fixed on central tube by deblocking pin.Upper end and the piston of described lock sleeve are threaded connection, and bottom is provided with interior step, and this interior step bottom is provided with interior lower inclined plane.Described lock ring is provided with ramp, and this ramp matches with the lower inclined plane of lock sleeve.The pressure transmission hole bottom of described central tube is provided with lower groove, and hanging ring and spacing ring to be installed on this in lower groove respectively.Described piston and be provided with sealing ring every the both sides of gland.Described piston, lock sleeve, form seal cavity every gland and central tube.
The present invention has the following advantages or beneficial effect compared with prior art:
(1), self-locking mechanism through optimization, adopt lock ring divide equally six lobe radially self-lockings and wave spring follow-up mode, realize the design of crawl space self-locking mechanism, and larger self-lock force can be provided;
(2), self-locking mechanism adopts wave spring, substantially reduces the length of instrument, thus reduces the difficulty that umbilical passes through.
(3), larger interior latus rectum can be kept;
(4), the screw thread that is connected with central tube of top connection is metal sealing button, and wall thickness is much smaller than the wall thickness of gas thread, but intensity is very high and can seal, and can increase the interior latus rectum of instrument to greatest extent;
(5), when suspension stays well casing post and oil-separating layer to pass through umbilical, easily and effectively manipulation is implemented on bottom fastening means and does not affect the function of packer oil-separating layer;
(6), optimize solution sealing mechanism, even if the hypertonia below packing element, deblocking pin still can not bear shearing force, can only by carry packer and carry out deblocking.
Accompanying drawing explanation
Fig. 1 is a kind of example structure schematic diagram of the present invention;
Fig. 2 is for by the A-A cross-sectional view shown in Fig. 1.
Detailed description of the invention
Consult Fig. 1-Fig. 2, a kind of smart well top packer, comprise top connection 1, central tube 2, slips cover 3, stage clip 4, slips 5, cone 7, adjustable ring 8, packing element 9, piston 10, hanging ring 13, every gland 16, spacing ring 17, deblocking pin 18, stop collar 19, lock sleeve 20, lock ring 21, spring 22, pressure cap 23, lower contact 24.Central tube 2 top is connected with top connection 1, bottom is connected with lower contact 24, central tube 2 is outer is connected and installed with slips cover 3 in turn, stage clip 4, slips 5, cone 7, adjustable ring 8, packing element 9, piston 10, lock sleeve 20 and pressure cap 23, be provided with in piston 10 lower pressing cap 23 every gland 16, stop collar 19, lock ring 21 and spring 22, piston 10 times, hanging ring 13 is installed on gland 16, every gland 16 times, stop collar 19 is provided with spacing ring 17, outside stop collar 19, in lock sleeve 20 and on lower pressing cap 23, lock ring 21 and spring 22 are installed, the wall of central tube 2 is provided with vertical line umbilical and passes through hole 12.
The wall of central tube 2 is provided with at least one (being expressed as 4 in figure) vertical line umbilical and passes through hole 12, and middle part is provided with at least one (being expressed as 1 in figure) pressure transmission hole 15.Stop collar 19, lock sleeve 20, lock ring 21, spring 22 and pressure cap 23 form self-locking mechanism.Cone 7 is fixed on central tube 2 by safety pin 6.Stop collar 19 is fixed on central tube 2 by deblocking pin 18.Upper end and the piston 10 of lock sleeve 20 are threaded connection, and bottom is provided with interior step, and this interior step bottom is provided with interior lower inclined plane.Lock ring 21 is provided with ramp, and this ramp matches with the lower inclined plane of lock sleeve 20.Pressure transmission hole 15 bottom of central tube 2 is provided with lower groove, and hanging ring 13 and spacing ring 17 to be installed on this in lower groove respectively.Piston 10 and be provided with sealing ring 11 every the both sides of gland 16.Piston 10, lock sleeve 20, form seal cavity every gland 16 and central tube 2.
During operation, smart well top packer is connected on operating tool string, be lowered into the precalculated position of oil well, then operating tool string is just suppressed, current by pressure transmission hole 15 flow into piston 10, lock sleeve 20, every gland 16, central tube 2 form seal cavity, promote piston 10 up, thrust is delivered in cone 7 by packing element 9, when pressure reaches setting numerical value, safety pin 6 is cut off, and cone 7 is up, promote slips 5 externally to open, be fixed on sleeve pipe, packing element 9 is squeezed and outwards expands simultaneously, the packing of both sides up and down of packing element 9 is opened.While piston 10 is up, drives lock sleeve 20, lock ring 21, spring 22, pressure cap 23 up, and prevent piston 10 descending by auto-lock function.Like this, packer completes setting.
Connect lower tool because hydraulic line or cable pass through hole 12 through the umbilical of central tube 2, to the execution of instrument manipulation below packer, and can not affect the function of packer oil-separating layer on ground; When packer needs deblocking, on put on joint 1, because packer is setting, all parts of central tube 2 outside are in stationary state relative to sleeve pipe, only have central tube 2 meeting up, thus cut off deblocking pin 18, all parts of central tube 2 outside move down, and slips 5 is regained under the effect of stage clip 4, and packing element 7 affranchises state, the parts of central tube 2 outside are suspended on central tube 2 by hanging ring 13, and packer completes deblocking.Can lower tool be connected, and on the ground other execution of instrument be manipulated.
