Description
Technical field
The present invention and oil exploitation intelligent well completion process tool, more particularly to a kind of smart well top packer.
Background technology
Intelligent Well Completion by umbilical realize ground in the face of downhole oil gas-bearing formation production control, existing top packer its
Structure is latus rectum in reducing, and on the wall of packer central tube, design vertical line umbilical passes through hole, is oil exploitation intelligent well completion
Technology has played effect, but which haves the shortcomings that following or deficiency simultaneously：1. because top packer will pass through umbilical, cause
In packer, latus rectum diminishes, and enters difficulty under subsequent job instrument；If interior latus rectum 2. will be increased, packer radial thickness can subtract
Little, self-locking mechanism design difficulty is big, it is impossible to provide larger self-lock force；3. the difficulty passed through for reduction umbilical, packer body
Design length should also be shortened as far as possible；4. stress levels are low, during hypertonia below the packing element, may cause removing seal for packer,
Under the higher environment of pressure rating, need to assemble the security that anchor watt just can guarantee that instrument.
The content of the invention
It is an object of the invention to provide a kind of smart well top packer, is provided with vertical line umbilical using the wall of central tube and wears
More hole, middle part is provided with pressure transmission hole and stop collar, lock sleeve, lock ring, spring and pressure cap constitute the structure of self-locking mechanism, effectively
Overcome or avoid shortcoming or deficiency present in above-mentioned prior art.
Smart well top packer of the present invention, including top connection, central tube, slips cover, stage clip, slips, cone,
Regulation ring, packing element, piston, hanging ring, every gland, spacing ring, deblocking pin, stop collar, lock sleeve, lock ring, spring, pressure cap,
Lower contact, it is characterised in that the central tube top is connected with top connection, and bottom is connected with lower contact, outside central tube sequentially
It is connected and installed with peace in slips cover, stage clip, slips, cone, regulation ring, packing element, piston, lock sleeve and pressure cap, piston lower pressing cap
Equipped with every gland, stop collar, lock ring and spring, hanging ring is installed under piston, on gland, pacifies under gland, on stop collar
Lock ring and spring are installed outside equipped with spacing ring, stop collar, in lock sleeve and on lower pressing cap, the wall of central tube is provided with vertical line pipe
Cable passes through hole.
Wherein, the wall of the central tube is provided with least one vertical line umbilical and passes through hole, and middle part is provided with least one pressure transmission
Hole.The stop collar, lock sleeve, lock ring, spring and pressure cap constitute self-locking mechanism.The cone 7 is fixed on by safety pin
On central tube.The stop collar is fixed on central tube by unsealing pin.The upper end of the lock sleeve passes through screw thread with piston
Connection, bottom are provided with interior step, and the interior step bottom is provided with interior lower inclined plane.The lock ring is provided with ramp, the ramp with
The lower inclined plane of lock sleeve is engaged.The pressure transmission hole bottom of the central tube is provided with lower groove, and hanging ring and spacing ring are pacified respectively
Loaded in lower groove on this.The piston and sealing ring is installed every the both sides of gland.The piston, lock sleeve, every gland and
Central tube constitutes sealing space.
The present invention has advantages below or beneficial effect compared with prior art：
（1）, self-locking mechanism through optimization, by the way of lock ring respectively six lobe radially self-lockings and wave spring follow-up, realize
The design of crawl space self-locking mechanism, and larger self-lock force can be provided；
（2）, self-locking mechanism adopt wave spring, substantially reduce the length of instrument, so as to reduce the difficulty that umbilical is passed through.
（3）, larger interior latus rectum can be kept；
（4）, the screw thread that is connected with central tube of top connection be metal sealing button, wall thickness of the wall thickness much smaller than pipe screw 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, it is easy to implement to bottom fastening means effectively to grasp
Control and do not affect the function of packer oil-separating layer；
（6）, optimize solution sealing mechanism, even if the hypertonia below packing element, deblocking pin be still not subject to
Shearing force, can only be unsealed by above carrying packer.
Description of the drawings
Fig. 1 is a kind of example structure schematic diagram of the present invention；
Fig. 2 is A-A cross-sectional views as shown in Figure 1.
Specific embodiment
Refering to Fig. 1-Fig. 2, a kind of smart well top packer, including top connection 1, central tube 2, slips cover 3, stage clip 4, card
Watts 5, cone 7, regulation ring 8, packing element 9, piston 10, hanging ring 13, every gland 16, spacing ring 17, deblocking pin 18, stop collar
19th, lock sleeve 20, lock ring 21, spring 22, pressure cap 23, lower contact 24.2 top of central tube is connected with top connection 1, and bottom is with
Joint 24 is connected, be sequentially connected with outside central tube 2 be provided with slips cover 3, stage clip 4, slips 5, cone 7, regulation ring 8, packing element 9,
Piston 10, lock sleeve 20 and pressure cap 23, are provided with every gland 16, stop collar 19, lock ring 21 and spring in 10 lower pressing cap 23 of piston
22, hanging ring 13 is installed under piston 10, on gland 16, restraining position ring block 17 is installed under gland 16, on stop collar 19, it is spacing
Lock ring 21 and spring 22 are installed outside set 19, in lock sleeve 20 and on lower pressing cap 23, the wall of central tube 2 is provided with vertical line umbilical and wears
More hole 12.
The wall of central tube 2 is provided with least one（4 are expressed as in figure）Vertical line umbilical passes through hole 12, and middle part is provided with least
One（1 is expressed as in figure）Pressure transmission hole 15.Stop collar 19, lock sleeve 20, lock ring 21, spring 22 and pressure cap 23 are constituted from lock machine
Structure.Cone 7 is fixed on central tube 2 by safety pin 6.Stop collar 19 is fixed on central tube 2 by unsealing pin 18.Lock
The upper end of tight set 20 is threaded connection with piston 10, and bottom is provided with interior step, and the interior step bottom is provided with interior lower inclined plane.Lock ring
