摘要
高含硫天然气井一旦发生井喷,含硫气体会迅速扩散,对人员的生命健康和环境安全造成巨大威胁。准确模拟井喷后高含硫气体的扩散过程,有助于掌握和了解有毒气体的扩散规律并制订有效的应急措施,进而避免或降低高含硫气体扩散造成的危害。为此,在大量文献调研的基础上,分析了影响高含硫气体扩散的内部和外部因素,系统综述了高含硫气体扩散模拟技术的原理及其主要特点,最后展望了复杂地形和气象条件下井喷后高含硫气体扩散模拟技术的发展趋势。研究结果表明:①影响井喷后高含硫气体扩散的主要因素包括泄漏源、气象、地形地貌和物理化学作用等,需要综合考虑内外部因素的耦合作用才能准确模拟高含硫气体的动态扩散规律;②研究高含硫气体扩散规律的主要方法包括现场模拟试验、风洞模拟试验、数值模拟分析、数学模型及专业软件等,合理选择研究手段或方法可以更加准确地模拟高含硫气体的动态扩散规律,对指导应急和救援措施的制订与实施具有重要意义;③针对复杂地形和气象条件下的井喷后高含硫气体扩散问题,未来应结合人工智能技术,开发具备高含硫气体扩散模拟、泄漏监测预警、应急决策支持功能的综合性软件系统,发挥模拟—监测一体化作用。结论认为,提出的井喷后高含硫气体扩散过程模拟软件系统可为高含硫天然气勘探开发的安全性评价、应急和安全防控措施制订提供重要支撑,对于保障人民生命安全和保护自然环境具有重要作用。
Once a blowout occurs in a high-sulfur gas well,sulfur gas will spread rapidly,posing a great threat to human life and health and environmental safety.Accurate simulation of sulfur gas diffusion after blowout is helpful in understanding the diffusion pattern of toxic gas and thus formulate effective emergency measures to avoid or reduce the possible damage caused by the diffusion of sulfur gas.Based on literature review,the internal and external factors affecting the diffusion of sulfur gas are analyzed.The principles and features of sulfur gas diffusion simulation technology are expounded.Finally,the prospect of simulation technology of sulfur gas diffusion after blowout under complex terrain and meteorological conditions is proposed.The following results are obtained.First,the main factors for sulfur gas diffusion after blowout include leakage source,meteorology,topography,and physical and chemical interactions.The coupling of internal and external factors should be considered to accurately simulate the dynamic pattern of sulfur gas diffusion.Second,the pattern of sulfur gas diffusion is mainly investigated by field simulation,wind tunnel simulation,numerical simulation,mathematical model,professional software,or other means,which can be rationally selected to provide a more accurate simulation of sulfur gas diffusion,thereby guiding the development and implementation of emergency and rescue measures.Third,to deal with sulfur gas diffusion after blowout under complex terrain and meteorological conditions,an integrated software system incorporating sulfur gas diffusion simulation,leakage monitoring and early warning,and emergency decision support will be established in conjunction with artificial intelligence technology.This system will allow for integrated simulation and monitoring.It is concluded that the proposed simulation software system for sulfur gas diffusion after blowout can greatly support the safety assessment and the preparation of emergency response and control measures in sulfur gas exploration and development.It plays an important role in ensuring people's life safety and natural environment.
