Inside Blowout Control Tools
During the drilling process, when the local formation pressure exceeds the static hydraulic column pressure of the drilling fluid, in order to prevent the drilling fluid from spraying upwards along the water hole of the drilling column and prevent the faucet from being damaged due to high pressure, internal blowout prevention tools need to be used. The commonly used internal blowout control tools for downhole operations mainly include Kelly valves, Tubing valves, fully open safety valves(FOSV), IBOP, check valves, float valves, bypass valves, etc.
