Features：
The cup packer is a special kind packer that designed for the demand of on-site well situation .Due to the oil surface is shallow ,other tools do not have the better sealing capacity ,however the cup packer can solve this problem .The cup packer is a kind of self-sealing packer ,seal the oil sleeve annulus by means of the surface of packing leather and casing inner wall ,the packing leather stretch sealing annulus under the action of the pressure difference in the well,only endure the larger pressure difference in unidirection.The key part of cup packer is cone cup, it is formed by valcanization with the rubber on the metallic framework,lowering into the wall with other downhole tool ,when the tools reach the designed postion, they can seal by means of the contraction of the packer leather and inner wall of casing and the pressure difference,pull up the tubular column directly to relieve the sealing dureing the well reparing.the cup packer our company manufactured adopt the high abasive resistance pack leather which use the manganese steel as framework as sealing element .It has the feature of long duration and simple structure ,easy operation and the practicability is perfect.
