Abstract
The utility model relates to a recovery type high temperature and high pressure packer which is an oil and water well completing tool used in oil fields and solves the problems that slips are easy to fall off, solitary anchorage is not firm and safety accidents are easy to occur. The utility model is formed by the connection of a hydraulic anchor body, a liner tube, a sealing ring, anchor palms, a spring, a pressing plate, a pin, an upper contact, a valve sleeve, a valve body, a sealing packing, an upper protective sleeve, a rubber barrel, an upper central tube, a rubber tube spacer ring, an inner central tube, a lower protective sleeve, a slip seat, a fall-off screw bolt, a slip, a slip retaining sleeve, an outer hoop sleeve, a connection clamping hoop, a centralizing position changing sleeve, a friction sheet upper sleeve, a friction sheet, a sheet-shaped pressure spring, a friction sheet lower sleeve and a lower central tube. The utility model has the advantages that a well back flushing passage of the packer is short, and the blocking and clamping problems are solved; the work efficiency is high, and the anchorage is reliable; the slip retaining sleeve has an integral structure, so that the slip can be effectively prevented from falling off.
