Rotating control head (test tree) is mainly used to control the ground pressure of DST and the flow of liquids and gases, open wells in the beginning of a very short period of time to lift more than conventional tools stratigraphic pressure. Since flow resistance is small, high-pressure oil and gas wells in the test easy to plug, more truly reflect the formation fluid flows. In addition, the device path for the whole structure, and its diameter can be passed to meet the needs of downhole tools.
