Claim:
A downhole jet cutting tool comprising: a housing having an upper end for connection to a conduit string for running the downhole jet cutting tool into a well, the housing having a passageway for communicating a cutting fluid pumping down the conduit string to the downhole jet cutting tool; an inflatable member operatively associated with the passageway whereby the inflatable member is inflated by the cutting fluid, the inflatable member having an initial position and a plurality of inflated positions; and a jet nozzle assembly, the jet nozzle assembly comprising a cutting head having a nozzle for expelling the cutting fluid, the jet nozzle assembly being disposed on an outer wall surface of the inflatable member so that as the inflatable member moves from the initial position to the plurality of inflated positions, the jet nozzle assembly moves from a retracted position to a plurality of corresponding extended positions, wherein the passageway of the housing and the nozzle of the cutting head are in fluid communication with each other such that the cutting fluid can flow from the passageway and out of the nozzle at a pressure sufficient to cut a cutting surface disposed within the well.
