| Abstract: | This paper is to analyze the influence of ignition time of high-sulfur well blowout.First investigated a serious accident of high-sulfur content blowout in China,Second large eddy simulation method was adopted for simulating the gaseous diffusion in blowout,and the calculation result was compared with the actual investigation result on the spot.Through calculation to the disastrous aftermath caused in the accident at different ignition time,the influence of ignition on the disaster was got.Through calculation to the diffusion distance with various meteorological conditions,reasonable ignition time standard was put forward.A conclusion that ignition at 15 minutes is optimal is drew. |
