OSTI ID:5358261
This patent describes a packer for running on coiled tubing inside a well tubing that can be set by reciprocation of the tubing. It comprises a mandrel for attaching to the end of the coiled tubing, a lower packer head attached to the mandrel, an annular packing element on the mandrel supported by the packer head, an upper packer head having a conical outer surface, a slip assembly carried by the mandrel and including slips and means for engaging the well tubing and frictionally resisting movement of the slip means through the well casing, and means connecting the slip assembly to the mandrel to limit upward movement of the slip means relative to the mandrel as the packer is being run into the well tubing and upon reciprocation of the mandrel for allowing the mandrel to move upwardly moving the outer conical surface of the upper packer head under the slips forcing the slips into engagement with the well tubing to hold the upper packer head against further upward movement to allow continued upward movement of the mandrel to compress the packing element between the upper and lower packer heads and force the packing element into sealing engagement with the mandrel and the well tubing.
