摘要:
为研究海上钻探平台井喷燃爆事故后果，运用FLACS软件对某深海钻探平台井喷爆炸事故进行模拟，研究在不同事故场景下气云爆炸发展过程及平台荷载分布规律，讨论井喷速率、风向、点火位置等对爆炸超压的影响。研究结果表明：随泄漏速率增加，爆炸强度和爆炸范围均增大，爆炸严重程度不仅与井喷速率密切相关，同时也受平台结构影响；点火位置会对爆炸超压产生影响，在可燃气体与空气混合气体比例为化学理论当量比处点燃气体，生活区承受的爆炸超压最大；在设施及建构筑物分布较为密集、拥塞度较高的地方产生的爆炸超压更大。研究结果可为可为平台的阻隔防爆性能设计与应急响应提供指导。
Abstract:
In order to study the consequence of blowout and explosion accidents on the offshore drilling platforms,the FLACS software was used to simulate the blowout and explosion accident on a deep-sea drilling platform.The development process of gas cloud explosion and the distribution law of platform load under different accident scenarios were studied,and the influence of blowout rate,wind direction,ignition position,etc.on the explosion overpressure was discussed.The results showed that as the leakage rate increased,both the intensity and range of explosion increased,and the severity of explosion was not only closely related to the blowout rate,but also affected by the platform structure.The ignition position would affect the explosion overpressure,and when the gas mixture ratio of combustible gas and air was ignited at the chemical theoretical equivalent ratio,the explosion overpressure in the living area was the largest.Where the facilities and buildings were densely distributed and the congestion degree was higher,the explosion overpressure was greater.The research results can provide guidance for the barrier explosion-proof performance design and emergency response on the platform.
