井喷硫化氢扩散分析

Analysis on dispersion of H_2S during well blowout

井喷有毒气体扩散对周围居民的危害很大[1],由于井场所位于的山区地形下垫面特殊,气体扩散的过程比较复杂,无法用普通的烟羽模式进行模拟,本文采用大涡模型以及贴体网格技术、卫星遥感技术,对某地区发生泄漏进行研究并进行三维数值模拟,模拟结果显示了气体扩散的时空分布以及对人员的危害,通过模拟结果,可以对井场地区的安全情况作出评价,能够对应急人员疏散策略及安全区域规划的制定提供帮助。

It is so danger to people who lived mon plume mode can not be used to simulate ous area. In this article, some methods were analysis, satellite remote sensing technology, disaster occurrence was studied by dynamics. an accident in some mountainous area. can be drawed through the example that safety planning, disaster prevention and nearby the place where poison gas blowed out from sour gas well. The cornthe dispersion, because process of gas dispersion is complex over mountainapplied to improve LES computation technology such as body - fitted grid 3D automated adaptive refinement of all element meshes. The mechanism of The space and time gas distribution of blowout was processed by simulating of disaster was obtained through the result of simulation. The conclusion numerical simulation can goes a step further with policy - making support about emergency response.
