摘要
应用高斯烟羽模型计算在井喷失控条件下天然气的扩散浓度,并通过典型高山地形烟流运行轨迹规律,对烟羽模型进行修正,得出山地井喷流扩散模型。选取合适的扩散模型各参数的求取方法,其测算的数据与现场有较好拟合,为高含硫气田井喷后的救援提供了参考数据。
In this paper, Gauss Plume model was applied to calculating the concentration of natural gas diffusion under the condition of uncontrolled blowout. And the model was modified by the law of plume trajectory of typical alpine terrain to establish gas diffusion model of blowout in mountainous region. Suitable methods were adopted to calculate parameters of the diffusion model, resulting in good matching between the calculated ones and the field data. Therefore, this study provides a reference for the rescue of blowout of high-sour gasfield.
