Passing shuttle packets are designed to reliable insulation of gas -and -bearing layers and the prevention of interpoplanes. The passage packer descends as part of the casing and does not overlap the inner cavity of the casing. Since the issues of high -quality replacement with a tampon solution of drilling, the destruction of the clay crust before cementing and other problems of reliable separation of the layers have not yet been resolved, the installation of an shock packer, especially in the conditions of a close location of the layers, is often the only solution to the qualitative division of the layers. In addition, shuttle packers are used to divide the layers without cementing. In addition, the nuclear curtain cementing packers are used, which are a symbiosis of
