钻前检验是排查安全隐患,提供安全预警的重要手段。论述了钻前检验的主要检验项,将检验结果分为关键问题、主要问题和一般问题三类;对近三年南海东部地区海上钻井设施具体检验结果进行了统计分析,并针对新旧平台存在的问题提出相应的预防措施和建议。研究表明:近三年,关键问题的比例和数量均呈逐年递减趋势,钻前检验可有效的发现关键问题并通过整改从而降低安全风险,为钻完井作业提供有力的保障;新平台三类问题平均值均多于老平台,实际工作中要加大对新平台的钻前安全检查;针对新旧平台提出了各类问题的主要防治措施和建议,为南海东部海上设施后期的钻前检验和安全预防工作奠定了一定基础。
Pre-drilling inspection is to investigate potential safety hazards and provide an important means of safety early warning. The main test items of pre-drilling test are discussed. The test results are divided into three categories: key problems, general problems and problems. The statistical analysis of the specific test results of offshore drilling facilities in the eastern South China Sea in recent three years is carried out. The problem put forward the corresponding preventive measures and suggestions. The research shows that in the recent three years, the proportion and number of key problems have been declining year by year. The pre-drilling inspection can effectively identify key problems and rectify them so as to reduce the safety risk and provide strong protection for drilling and completion operations. The average value of the problems are more than the old platform, the actual work to increase the new platform pre-drill safety inspection; proposed for the old platform for a variety of major preventive measures and suggestions for the South China Sea in the late offshore pre-drilling test and Safety prevention laid a solid foundation.
