Integrated and back-off tubing string for the separate zone production in the reducing well is designed. Y341 and Y441 packer, hydraulically operated releasing tools, diverting switch and other matching bottom tools are developed. The tubing string is formed with highly reliable sealing ability on the confining zones below the diameter-reducing section. This tubing string is used to realize hydraulic setting and pull -to -release, which has the properties of small external diameter of the rigid body, reliable setting and sealing performance, high pressure bearing ability. Success of this technology in field indicates that the technology is worth applying widely.</em></p><p class='subject'><strong>关 键 词：</strong><a href='/subject/article.aspx?id=6747698'
