摘　　要：高含硫天然气井喷扩散将造成严重安全问题。为此文章分析了影响有毒气体扩散的因素包括气体扩散模式、泄露源类型、地理环境、气象条件等;为了准确评估含硫天然气扩散造成的影响,对几种常见气体扩散模型进行了比选,最终选用高斯模型和API模型计算出给定条件下高含硫天然气持续井喷的危害范围及后果。最后对模型的计算结果作了分析讨论,并提出了高含硫天然气井喷的防范措施。Blowout diffusion of natural gas with high sulfur may cause serious safe problems. The paper analyzes the factors effecting on poison gas diffusion, including gaseous diffusion models, types of leakage source, geographic setting, weather factors and gas properties. In order to accurately estimate the effect caused by the diffusion of gas with high sulfur, several models of common gas diffusion are selected. Eventually Gaussian model and API model are adopted to figure out the harzard scope and results of continuous blowout of high-sulfur gas under the given condition. Finally, calculation results are analyzed so as to propose some precautions against the blowout of high-sulfur gas .
