【Abstract】 This paper introduces structure and working principle of a new-style non-slip packer. The packer with simple structure overcomes contradiction between bearing up working pressure and released force of traditional non-slip packer.So, the packer is with high working pressure and long working life span. This packer is mainly used to block water tubing string with other down-hole controlling tools. It can block different kind formation’s water, and it can be used in mechanical finding water, acidization strings selection,ect.更多还原
