含硫气井的公众防护距离的判定法则研究

Determinant principle study of high sour gas well safety distance

高含硫气田井喷有毒气体扩散对周围居民的危害很大,通过安全防护距离的方法保护井口周边群众是国内目前比较认同的做法。但如何确立有效的安全距离既能有效的保护周边群众的生命安全又能减轻企业的经济负担成为比较难的课题。这要求对于计算硫化氢的扩散范围要相对准确,对于区域距离的判定更加符合实际情况。本文通过采用大涡模拟的方法来模拟事故的发生扩散情况,并在此基础上提出毒性负荷分析,来研究解决这一问题。

Poison gas from High sulfur gas field blowout is so dangerous to dweller nearby. It was deemed right to prevent the people from death in inland that setting up safety distance abound the well head. But how to confirm the effective safety distance is so difficult if we want to both protect people nearby and reduce the economy burden. To solve the problem, forecasting of gas diffusion must be more exactly and the determinant of the safety distance must accord the nature. In this article, we try to use LES module to simulate the gas diffusion of accidents and put forward the toxic load analysis.
