It closes, realizes the locking between outer cylinder 302 and connector sleeve 2, at this point, the first segment of elastomer 102 and outer cylinder 302 is in close contact,
Under extruding of the elastomer 102 by the first segment of outer cylinder 302, elastomer 102 gradually extend outwardly and sealing screw air deflector 1 with
Gap between tube inner wall, so that the fluid of underground is flowed into upwardly through the region between anchor block 304 from diversion trench 307
It in electric sealed vortex guiding device, by third through-hole 201, enters in connector sleeve 2, then is flowed by first through hole 201
Enter into the cavity in spiral stream guidance device 1, realizes downhole fluid along the continuous rotating separation of vortex sheet.
Finally, electric sealed vortex guiding device anchoring after, above mention steel wire make bumper jar and delivery tool with it is electronic
It is vortexed guiding device to disengage, electric sealed vortex guiding device is retained in oil pipe and is worked.
At the end of vortex drainage gas production process operation, the electric sealed vortex guiding device out is needed, firstly, logical
Cross on bumper jar to hit and cut pin 312, steel wire drives spiral stream guidance device 1 and connector sleeve 2 to move up so that anchor block 304 no longer with oil
Inside pipe wall is mutually anchored.
Secondly, bumper jar continue on hit, release the locking between self-locking ring 310 and connector sleeve 2, steel wire continues to drive spiral
Air deflector 1 and connector sleeve 2 move up.
Again, bumper jar continue on hit so that elastomer 102 inwardly bounces back, no longer in sealing screw air deflector 1 and oil pipe
Gap between wall, at this point, connector 7 is blocked using delivery tool, by pulling steel wire to fill electric sealed vortex water conservancy diversion
It sets and is taken out from well.
The above is merely for convenience of it will be understood by those skilled in the art that technical solution of the present invention, not to limit
The present invention.All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in this
Within the protection scope of invention.
