Firstly, from the analysis of the packer's development in the world. Understanding of the problems encountered by the packer and the future direction of development. Re-analysis of the structure and working principle of several typical hydraulic compression packer. Design, Analysis of the packer rubber tube material, the cross section bevel, side bevel and other combination of sealed cones, Select the packer rubber tube material for the hydrogenated nitrile rubber 更多：https://www.bmcx.com/ , Face angle is 30 ° ~ 40 °, the side shape is cylindrical, And glue one end of the cylinder with nylon 10 production of plastic outburst prevention device - add a shoulder. The shoulder pad and cones with vulcanizingFirmly glued together. And then calculate the part size and checking the strength, according to the size of a cad drawing, complete the design.

This article starts with the analysis of development of Packer, Packer now encountered issues and future directions. Analysis describes several kinds of hydraulic compressed-Packer's structure and how it works. To programme design, Analysis of the material of the sealing rubber of the Packer, section bevel, bevel side of the packer combination effect of sealing, Selected Packer rubber cylinders are made of hydrogenated acrylonitrile-butadiene rubber, Beveled 30 ° ~40 ° end 更多：https://www.bmcx.com/ , side shape of a cylinder, And glue one end of the tube to add a plastic made with nylon 10 "outburst" devices-shoulder, Vulcanization molding with the shoulder and Packer,Firmly stuck together. Calculation of checking the size and strength of the parts, CAD drawing according to size, complete the design.

This paper from the analysis of the packer and developing situation of domestic and foreign, packer and now know the problems and the future development direction. analyzes again introduces several kinds of typical hydraulic compression packer and type of structure and work principle. thus to design program, analyzes the packer and glue tube material, cross section bevel,Profile of glue tube diagonal combined sealing influence, chose the packer and glue tube material for hydrogenated butadiene acrylonitrile rubber, 30 ° to end bevel ~ 40 ° 更多：https://www.bmcx.com/ , side shape for the cylinder, and one end of the tube glue to add a with nylon 10 production of the plastic "the outburst" device-protecting shoulder, the protecting shoulder rubber vulcanization molding and cylinder together,Firmly stuck together. again calculate the parts size and checked strength, again according to size CAD drawing, complete the design.
