ABSTRACT:
A tubing string testing tool having three separate isolated passageways for allowing separate and independent control over the packer or sealing systems as well as for each of two separate testing fluids. The tool is comprised of a plurality of separateable elements that can be connected together to develop the desired length testing tool to correctly position sealing assemblies along the interior of the tubing string to form annular test cavities within the tubing string to isolate joints and tubing wall sections so that a plurality of joints and tubing wall sections can be simultaneously tested. Each of the separate elements include three internal passageway systems and the connection between each employs three separate annular chambers for interconnecting the passageways together between the elements and along the entire length of the tool or along desired portions of that length.
