井喷事故后果严重,特别是当井喷物质中含有H_2S等有毒气体时,会造成重大的人员伤亡和财产损失。为了研究含H_2S天然气井喷事故后的安全疏散问题,建立了含H_2S天然气井井喷事故模型,对含H_2S天然气井喷事故进行数值模拟。模拟得到了含H_2S天然气井喷事故中井喷气体的浓度场分布情况。以此为依据确定安全疏散时间和最小安全疏散半径的计算方法,并通过模拟算例验证了方法的可靠性。
Blowout serious consequences, especially when the blowout substances containing H 2 S and other toxic gases, can cause significant casualties and property losses. In order to study the safety evacuation after H_2S natural gas blowout accident, a blowout accident model of H_2S natural gas well was established to simulate the blowout accident of H_2S natural gas. The concentration field distribution of well blowout gas during well blowout with H_2S gas was simulated. Based on this, the method of calculating the evacuation time and the minimum evacuation radius were determined. The simulation results show the reliability of the method.
