井喷失控着火事故后果模拟预测

SIMULATE AND FORECAST CONSEQUENCES OF THE OUT-OF-CONTROL GAS WELL FIRE ACCIDENT

以迪那2井为研究对象,运用 CFD 方法模拟预测井喷失控着火事故后果,并根据人和设备所能承受的热辐射通量得出不同伤害等级的伤害半径。通过模拟不同风力等级下的井喷失控着火得出,在风力等级3～4时造成的伤害范围最大,伤害程度最深。研究为制定事故现场逃生预案和救援措施以及井场设备的布置提供了有力依据。

With the Study object of Dina 2 well,this paper has simulated and forecasted consequences of the out-of-control gas well fire accident with the CFD method,obtained the injury radius of different injury grade according to the thermal radiation inten- sity person and equipment can bear.The conclusion that between wind scale three and four the injury ex- tent resulted from the accident will be highest ob- tained through simulating out-of-control gas well fire under different wind scale.Through this research the powerful basis been provided for making of escape plan,rescue measures and arrange equipments.
