Application of combining tech of perforation with passing pressure by bypass valve and APR test tool
Keywords:
APR testing tool, Perforation and test combination techAbstract
Conventional TCP tech is only limited to the combination of that with MFE tool which accomplishes opening or closing the down valve by hoisting up or setting down testing string and not suits for operation of special well to cause low successful ratio and safe reliability. Combining tech of perforation with passing pressure by bypass valve and APR testing tool, by applying annulus pressure to execute perforation and make true operation of open and close well, rises up the successful ratio greatly and upgrade operational safety.
