摘要： A differential pressure indicator (DPI) for use with a downhole isolation valve includes a tubular mandrel for assembly as part of a casing string and for receiving a tubular string. The mandrel has a stop shoulder and a piston shoulder. The DPI further includes a tubular housing for assembly as part of the casing string and for receiving the tubular string. The housing is movable relative to the mandrel between an extended position and a retracted position and has a stop shoulder and a piston shoulder. The DPI further includes a hydraulic chamber formed between the piston shoulders and a coupling in communication with the hydraulic chamber and for connection to a sensing line. The housing is movable relative to the mandrel and to the extended position in response to tension exerted on the DPI.
