在油气勘探和开发过程中不可控井喷是最危险的事故之一。一些重大的HSE问题涉及到作业人员的安全风险、潜在的健康伤害以及对环境的影响。通过特定模型评价井喷,商业软件往往分析不够详细而且容易低估井喷的后果。文献中提到的一些井喷事故不能得到充分的处理,因此为了全面分析和扩展特定数据库以及开发和验证简单模型.实验或计算流体力学研究是必要的、有效的。意大利埃尼石油公司1998年就已经制定了一个专门的研究与发展计划。本文应用计算流体力学方法描述了一些井喷模拟。喷射到大气中的气流在形态和浓度方面严重影响了云层的演变,并且伴随着热量辐射传播可燃性有毒气体。
Uncontrollable blowout in the exploration and development of oil and gas is one of the most dangerous accidents. Some major HSE issues relate to worker safety risks, potential health hazards, and environmental impacts. Evaluating blowout through a specific model, commercial software often fails to be analyzed in sufficient detail and can easily underestimate blowout consequences. Some of the blow-out incidents mentioned in the literature can not be adequately addressed, so experimental or computational fluid dynamics studies are necessary and effective in order to fully analyze and extend specific databases and to develop and validate simple models. Eni oil company in Italy in 1998 has developed a special research and development plan. In this paper, some well blowout simulations are described using computational fluid dynamics. The air stream injected into the atmosphere severely affects the evolution of clouds in terms of morphology and concentration, and propagates flammable toxic gases with heat radiation.
