摘要:

为了保证海底油气管道安全运营,实现海底油气田安全生产和可持续发展,需要对海底油气管道进行风险评估.根据国外标准规范和工程经验,阐述了评估海底油气管道稳定性风险的技术思路,就危险辨识,后果评估,频率分析和风险矩阵等4个因素探讨了管道风险的评估方法,重点研究了影响海底油气管道稳定性的风险情况和相应的评估准则.最后结合海底管道的特点总结了影响海底油气管道稳定性的危险因素,使用半定量评估法和定性评估法对海底油气管道稳定性风险进行了评估,给出了稳定性风险评估的主要项目和相应的推荐权重值.研究结果对推进我国海底油气管道风险评估技术进步具有一定的参考意义.

Abstract:

Pipeline stability is an important parameter of subsea pipeline service. In order to ensure the safe operation of the subsea oil and gas pipeline, so as to a chieve the safe production and sustainable development of subsea oil and gas field, risk evaluation of the subsea pipeline is required. research the technical methodology of subsea pipeline stability risk evaluation based on the worldwide standard and engineering experience. Firstly, four objects are described regarding to the risk evaluation, i.e., risk recognition, result evaluation, frequency analysis and risk matrix. Then the risk condition and evaluation methodology of subsea oil and gas pipeline stability are researched. Finally, the risk factors of subsea oil and gas pipeline stability are summarized based on the particularity of subsea pipeline. The semiquantitative evaluation method and qualitative evaluation method are used for subsea oil and gas pipeline stability risk evaluation. The results can be used for improving the accuracy of oil and gas pipeline risk assessment and promoting the related technical progress in.

Key words: subsea pipeline, oil and gas pipeline, risk evaluation, risk matrix, evaluation weight
