基于FLUENT的海上平台天然气泄漏扩散分析

为了解平台天然气泄漏和扩散情况,针对实际生产风险提出改善建议,对3个真实海上平台及环境进行调研,通过FLUENT软件进行泄漏和扩散模拟。模拟结果显示,强风向作用下泄漏气体的影响范围较小、影响的设备也较少。当N风向风速为9 m/s以及E风向风速为7 m/s时,泄漏可燃气体残留体积相对较大,影响的范围也相对较大。4口井的总体泄漏量小,泄漏影响范围不大。

In order to understand the natural gas leakage and diffusion of the platform,some suggestions are put forward to improve the actual production risk,three real offshore platforms and environments are investigated,and the leakage and diffusion are simulated by FLUENT software.The simulation results show that under the action of strong wind,the influence range of gas leakage is smaller and the influence of equipment is also less.When the wind speed in N direction is 9 m/s and the wind speed in E direction is 7 m/s,the residual volume of combustible gas leakage is relatively large,and the range of influence is also relatively large.The overall leakage of the 4 wells is small,and the scope of leakage influence is not large.
