1. well control product and the characterization processes of well head set-up under high temperature gas medium state is characterized in that:

  • comprise a, detected member is installed on the pick-up unit, detected member is connected with pressue device again that described detected member is a by-pass valve control;

    B, detected member inner cavity chamber air themperature is heated to 60 ℃

    -121 ℃

    of high temperature rated, and temperature is remained on the rated temperature value;

    C, unlatching pressue device are forced into rated operating pressure 1-140MPa with detected member;

    D, voltage stabilizing 0.5-2 hour, gather the temperature and pressure value of detected member, judge that according to the undulating quantity of temperature and pressure value detected member quality and performance be whether qualified after, pressure is reduced to 0MPa, the completion detection.
