深水气井泄漏量化风险评估方法研究

Research on Quantitative Risk Assessment Method for Deepwater Gas Wells Leakage

深水气井泄漏是油气勘探开发中的重要安全问题,随着生产时间的增加,泄漏风险日益增高,可能造成严重后果。因此,文章基于故障树及风险矩阵法,构建深水气井泄漏量化风险评估方法,并以南海某深水气井为例进行分析。研究表明,该井泄漏可能性较高,泄漏后果为一般,风险等级为8,属于C3类井,应加强监控或采取预防和降低风险的控制措施。该方法能够有效评估深水气井泄漏的风险水平,为海洋油气勘探开发提供决策支持。

Deepwater gas wells leakage is an important safety problem in oil and gas exploration and development.With the increase of production time,the risk of leakage is increasing day by day,which may cause serious consequences.Therefore,based on fault tree and risk matrix method,this paper constructs a quantitative risk assessment method for deepwater gas well leakage,and takes a deepwater gas well in the South China Sea as an example,the research shows that the well has a high probability of leakage,and the consequences of leakage are general,the risk level is 8,and it belongs to class C3 well.It should strengthen monitoring or take control measures to prevent and reduce the risk.This method can effectively assess the risk level of deepwater gas well leakage and provide decision support for offshore oil and gas exploration and development.
