Development of the hydroulic packer for dissociation the intervals of open trunk of the well in case of wells multistage completion

Work on development of behind-the-casing hydraulic packer for isolation the segments of not surrounded trunk in a horizontal well in case of multistage pumping of a well by hydraulic fracturing was carried out The received results are given, benefits of the provided design of a packer and its technical characteristics are described. The main arising problems in operation of the packer equipment in an open trunk of a well and methods of their decision are considered.
