An inflatable packer system for use in a well testing or treating tool which is attached to a drill string. The inflatable packer system comprises a pump subassembly operated by rotation of the drill string, a check/relief valve subassembly, valve subassembly, packer deflate subassembly, at least one inflatable packer, at least one flow subassembly, at least one recorder subassembly, and a drag spring unit. The packer system may also incorporate a straddle by-pass extension assembly for additional spacing between packers in a two packer straddle test. The inflatable packer system is used to isolate any desired zone or zones in a well bore so that multiple tests involving inflation and deflation of the packer(s) without removing the tool from the well may be performed.
