CFX软件在含硫天然气开发环境风险评价中的应用

The Application of CFX Numerical Simulation on the Environmental Risk Assessment during the Sulfur-containing Natural Gas Development

结合目前国内外对气体泄漏、扩散仿真分析的研究现状,对CFX软件在含硫天然气开发过程中的环境风险定量评估进行了介绍。并以某气田开发为实例,采用CFX软件对4类天然气泄漏风险事故进行了仿真计算,得到定量分析结果。该方法的应用将有助于含硫天然气在开发过程中的环境风险评价,并为风险搬迁与应急疏散范围的确定提供计算依据。

Combined with the research status of gas leakage and diffusion simulation,the application of CFX numerical simulation software is introduced for the environmental risk quantitative assessment during the sulfur-containing natural gas development.A gas filed development project was taken for an example while using the CFX to simulate four different gas leakage situations and drew a quantitative result.This application will be conductive to environmental risk assessment during the sulfur-containing natural gas development and provide the calculation support for the decision of relocating distance and the scope of emergency evacuation.
