Well piston.The described upper press ring lower end being connected with packing element axle be sequentially installed with upper packing element, test seal up pressure ring, test the lower pressure ring of envelope,
Lower rubber cylinder, lower pressure ring, lower pressure ring lower end female thread connects upper piston.Packing element axle pushes ring formation with testing to seal up pressure ring and test envelope
Install in ring cavity and test envelope piston by test that envelope shear pin connects, test envelope piston and connect with testing to seal outer intercommunicating pore and test intercommunicating pore in envelope
Logical, packing element axle and central canal are provided with hollow shear pin, are connected with testing envelope piston upper end by hollow shear pin.Test and seal up pressure ring, test
Envelope pushes interannular and is provided with tests envelope lock piston.
The threaded upper ends of above-mentioned upper piston connect lower pressure ring, the threaded adapter sleeve in its lower end, and lobe is opened in adapter sleeve lower end
Threaded central canal, by with lower contact with setting the lower piston support that shear pin is connected.
This utility model has the following characteristics that first, testing envelope shear pin and open and test sealing mechanism using testing envelope piston and cutting off, here
During, the closing chamber that two-stage packing element sets formation does not affect to test envelope piston and opens and normally opens it is ensured that testing sealing mechanism；Second,
It is connected with upper piston and lower pressure ring using connecting set upper side, lower end is connected with central canal using the screw thread opening lobe, is propped up by lower piston
Support, sets problem when lower piston does not suppress startup it is impossible to occur being hampered by mistake.

Specific embodiment
From testing envelope water injection packer, including central canal 23, the top connection 1 being connected with central canal upper end, well-flushing cylinder barrel 2, flat
Weighing apparatus plug 4, the lower contact 22 being connected with central canal lower end, lower cylinder barrel 21, sealing-plug 18, upper cylinder barrel 17, by unseal shear pin 29 and
Central canal connect packing element axle 24, the upper press ring 5 being connected with packing element axle, contiguous block 13, lock 15, lock 14, packing element axle and on
The well-flushing piston 3 installed between pressure ring and well-flushing cylinder barrel.Described upper press ring 5 lower end being connected with packing element axle 24 is sequentially installed with
Upper packing element 6, test and seal up pressure ring 7, test envelope lower pressure ring 10, lower rubber cylinder 11, lower pressure ring 12, lower pressure ring 12 lower end female thread connects lives
Plug 16, the threaded adapter sleeve in upper piston 16 lower end 19, the threaded central canal 23 of lobe is opened in adapter sleeve 19 lower end, by with connect
22 are supported with setting the lower pistons 20 of shear pin 30 connection.
Packing element axle 24 is sealed up pressure ring 7 and testing and is installed by testing what envelope shear pin 25 was connected in the ring cavity that the lower pressure ring 10 of envelope is formed with testing
Test envelope piston 9, test envelope piston 9 lower end and seal outer intercommunicating pore 27 and test intercommunicating pore 28 in envelope and connect with testing, packing element axle 24 and central canal
