摘要
随着油气田的不断开发与发展,越来越多的油气井由于长期运行存在套管失效、封隔器失效、井下安全阀故障、井口采油树老化等各种安全隐患,针对油气井失效模式开展油气井完整性定量风险分析尤为重要。油气井完整性定量风险分析方法在国内是一项全新的技术,是油气井完整性管理的一项重要组成部分,它贯穿于油气井整个生命周期的全过程。油气井完整性定量风险分析是通过油气井井屏障现状分析,识别泄漏途径,分析泄漏后果,最后确定风险等级的一种方法。
With the continuous exploration and development of oil and gas fields,various potential risks such as casing failure,packer failure,subsurface safety valve failure and wellhead tree aging tend to occur in more and more oil and gas wells due to their long-term operation.Therefore,aiming at the failure modes of oil and gas wells,it is especially important to carry out quantitative risk analysis of oil and gas well integrity. Quantitative risk analysis of oil and gas well integrity is a brand-new technology in our country which is an important part of oil and gas well integrity management. It is involved in the whole life cycle of oil and gas wells. Through analyzing the present situation of the well barrier,quantitative risk analysis of oil and gas well integrity can identify leakage ways,analyze leakage results and finally determine the risk levels.
