Abstract
A retrievable double grip well packer having an elongated tubular body, longitudinally spaced, upwardly holding and downwardly holding expander and slip mechanisms and an intermediate, elastomeric deformable packing which are sequentially expanded into anchoring and sealing engagement with the well casing upon relative longitudinal movement between the body and the upwardly holding and downwardly holding slip and cone mechanisms. The body is locked in position holding the packer set and anchored. The downwardly holding slip and cone mechanism is connected to the body by a releasable connection and the elastomeric packing is supported by a telescopic sleeve which enables the slip and cone mechanism to be easily released from the casing. The body and the upwardly holding slip and cone mechanism are constructed to enable the packer to be run on pipe and mechanically actuated by shifting the body relative to casing engaging friction means which effects expansion of the slip and cone mechanisms and the packing. The body and the upper slip mechanism are also structured to be actuated by fluid pressure from within the pipe acting on a pressure setting mechanism for setting the packer. In addition, the upwardly holding slip and cone mechanism and the body are constructed to receive an electric wire line setting tool for setting the packer.
