Description
Technical field
The utility model packer technology field, specially a kind of anchor packer.
Background technology
Packer meant with elastic sealing elements, and whereby between packing various sizes tubing string and well and tubing string it
Between annular space, and completely cut off payzone, to control to produce（Note）Liquid, protects the downhole tool of sleeve pipe.Packer is used in petroleum production engineering
To be layered, oil channel is designed with packer, when setting, piston bush is up, and oil channel is opened；After setting, upper lamination
Power is acted on dummy piston, pushes up packing element, makes deblocking pin from shearing force；During deblocking, by the friction of packing element and sleeve pipe
Power cuts deblocking pin, and piston bush is descending, closes oil channel.Wel packing plug water construction operation is reduced, can be easily
No killing well operation without open flow is realized, and two-way can bear high pressure, long service life.The conventional cup packer in oil field is self-styled
Formula.Its leather cup external diameter is more than casing inner diameter, and the sealing of packer, resistance when going into the well are realized by the interference fit of leather cup and sleeve pipe
Greatly, leather cup is easy to wear and scratches, so as to lose sealing.With the deep understanding to oil reservoir, it is imperative that thick oil pay is taped the latent power, together
When requirement higher is also proposed to downhole packer.Anchor packer is used so that packer enters into well in whereabouts simultaneously
The downslide of packer can be intercepted during bottom so that packer is easy to fix.
Utility model content
The purpose of this utility model is to provide a kind of anchor packer, with asking for solving to propose in above-mentioned background technology
Topic.
To achieve the above object, the utility model provides following technical scheme：A kind of anchor packer, including track centers
Pipe, described track centers pipe one end is provided with top connection, and the top connection right side is provided with and is placed on track centers pipe and by between spacer ring
Every sebific duct, sebific duct right side is cased with glue tube base, the cone for fitting in track centers pipe outer wall, institute is provided with the glue tube base
State cone side and be provided with slips, the slips side is provided with spring, and the spring side is provided with card in slip sleeve, the slip sleeve
Friction transposition body is connected to, the friction transposition body side is provided with friction plate, and the friction plate inner side is provided with friction plate leaf spring, described
Friction plate one end is provided with cuff under friction plate, and cuff inner side is provided with the transposition set for fitting in track centers pipe under the friction plate,
The transposition set is fixed on track centers pipe by reversing pin.
Preferably, positioned by fixing pin between the glue tube base and cone and fixed.
Preferably, it is fixedly connected by countersunk head screw between the slip sleeve and friction transposition body.
Preferably, the track centers pipe right-hand member is provided with variable buckle lower contact.
Compared with prior art, the beneficial effects of the utility model are：The utility model can have by the use of slips
What is imitated causes that packer easily can be fixed in well when in use, while can easily be received when packer is proposed outside well
Rise and cause the convenient proposition of packer so that the performance of packer is greatly improved.
