Analysis of blowout misfire and damage to emergency personnel in oil and natural gas wells

In the process of drilling or repairing oil and gas wells, sudden blowout fires may lead to huge economic losses, personnel injuries and environmental damage. In order to understand the effects of flame changes and high temperatures on the surrounding environment and human body during the blowout fire, a simulation model was established to analyze the situation according to the different blowout volumes and wind speeds. The results show that the increase of the blowout volume will aggravate the burning degree of the flame, and the larger the blowout volume, the more likely the flame vortex will occur. The wind speed tilts the flame, changing the shape of the flame, which affects the flame burning. When rescuing and repairing without precautions, the flame temperature and radiation will cause burns or even death to emergency responders in a very short period of time.
