technical field

The invention relates to the technical field of control systems, in particular to a control system for blowout simulation training.

Background technique

Blowout is a very taboo accident in oil or petroleum gas extraction. When drilling, mud is injected into the wellbore to balance the pressure of the underground formation. However, when the underground pressure test is inaccurate during the survey, or the density of the injected mud is too low, or the formation pressure suddenly increases, the oil or gas in the formation flows into the wellbore and is ejected out of the ground uncontrollably, resulting in a blowout. Often accompanied by toxic gas, causing greater harm to the environment and people.
