Utility model content
The purpose of this utility model is to provide a kind of well mouth pressure testing packer, to solve above-mentioned technical problem, to realize
Above-mentioned purpose the utility model uses following technical scheme：
A kind of well mouth pressure testing packer, including upper interface, adapter sleeve, central tube, packing element, clip spring seat, deblocking shear pin, jump ring
Frame, jump ring, setting shear pin, setting piston, oil pressure storehouse, centrum frame, centrum, slips, slip spider, base, deblocking shear pin and under connect
Mouthful, upper interface and lower interface are up big and down small taper, and lower interface radius is less than upper interface, upper interface and lower interface outer wall
On be threaded, and be threadedly coupled with adapter sleeve, central tube is arranged on the inside of packer, interface and lower interface in connection, glue
Cylinder is arranged on interface bottom, and jump ring frame is arranged on packing element bottom, and jump ring inframe wall sets jump ring, and clip spring seat is arranged on jump ring frame
On the outer wall of inside center pipe, and clip spring seat inside sets and unseals shear pin, the setting piston of clip spring seat bottom setting, in setting piston
Portion sets setting shear pin, and setting piston base sets oil pressure storehouse, and oil pressure storehouse sets cone frame, and cone inframe portion is set and jump ring frame
The same jump ring and clip spring seat, cone frame bottom set cone, and cone base sets slips, and slips bottom sets slip spider, card
Installation deblocking shear pin, slip spider bottom set base inside watt seat.
On the basis of above-mentioned technical proposal, the packing element uses the fourth as made from butadiene and acrylonitrile through emulsion polymerization
Nitrile rubber.
On the basis of above-mentioned technical proposal, the packer outer wall uses Inconel925 type nickel-base alloys.
It is reasonable that the packer of the utility model design is effectively carried out oil reservoir and water layer, while uses reasonable material, carries
The persistence and operation stability that height uses, the setting of packer is effectively improved by setting the structure of jump ring and clip spring seat to combine
Effect, by setting centrum frame to effectively improve the crystallized ability of packer, so as to improve the stability of packer, pass through the company of setting
The helicitic texture of female connector, facilitates packer to connect, and improves overall stability.
