FIELD: oil and gas extractive industry. ^ SUBSTANCE: system has upper and lower packers, each of which has body, shaft, anchor, compactors, and pipes, placed between packers. In shaft of upper packer a copier is made with fixing device of transporting and working position of anchor and a sub. The latter is mounted with possible axial displacement and rotation around the copier. Sub is placed on pipes between packers, mated to lower packer and has no capability for axial rotation and displacement relatively to their axis in operating position of lower packer. On lower packer shaft a copier is made with possible axial displacement with it for interaction with anchor and its displacement from transporting position to operation position. ^ EFFECT: simplified construction, broader functional capabilities. ^ 3 dwg |
