摘要
海洋石油钻完井作业风险高,极易发生井漏、井喷等井完整性事故。在役生产井生产年限越来越长,高温高压气井越来越多,环空带压问题日益突出。为了有效预防井完整性问题,提出基于安全屏障的井完整性问题分析模型,采用安全屏障、蝴蝶结、故障树与"人机物环法"5要素分析相结合的方法,分析事故发生及处理过程。
Offshore oil drilling and completion has high risk,easily occuring accidents of lost circulation,blowout and other well integrity problem.The production well age becomes longer and longer,and more HPHT wells bring more sustained casing pressure(SCP)problems.In order to effectively prevent and systematically analyze the causes and treatment of the well integrity problem,a model of well integrity problem analysis based on safety barrier is proposed.Combined with safety barrier,bow-tie,fault tree and“people,machine,material,environment,regulation”five element analysis,this paper analyzes accident occurrence and treatment process.
