安全管理首要基础是准确信息的快速、持续获得。能提供连续、系统、动态、可远程监控的录井技术正是这样的信息技术，其成为石油天然气钻探过程中最大的风险之——井控风险的安全管理中必不可少的环节，主要体现在井控安全管理的四大环节中最重要的一环——避免恶性应急发生的预警，应急发生后的动态决策依据提供，即避免发生应急、或发生应急时影响与损失最小化的临界控制环节。该项技术在钻探井控风险安全管理中广泛应用，通过技术集成、总结，正日趋成熟。通过该技术在防微杜渐，源头避免井控应急发生或发生后积极控制的应用分析，为企业重要安全管理环节的技术受控提供参考。

AbstractThe primary basis for safety management was the rapid and continuous access to accurate information.Logging technology was such information technology which could provide continuous,systematic, dynamic and remote monitoring.It was one of the greatest risks in the process of oil and gas drilling—the essential link in the safety management of well control, which was mainly reflected in the most important link of the four aspects for the safety management of well control—the early warning to avoid the occurrence of malignant contingency, and the basis of dynamic decision-making after the emergency.That is the critical control link of avoiding the occurrence of emergency, or minimizing the impact of emergency response and loss.The technology is widely used in drilling risk management and safety management, which is maturing through technology integration and summary.The technology provides a reference for the technical control of the important safety management through its application in the prevention of the slightest, the avoidance of well control emergency and the positive control after the occurrence.

1.引言

石油钻探过程中，钻遇高压油气流处置不当，造成井喷失控，轻则影响勘探开发部署，重则造成设备烧毁、人员伤亡、环境污染，后果严重，影响恶劣，恢复困难，因此井控工作是石油钻探安全工作重中之重，相关配套技术尤显重要，录井技术就是其中一项关键技术。

2010年4月20日22:00左右，BP公司位于美国路易安那州墨西哥湾的“深水地平线(Deeperwater Horizon)”钻井平台Missssppi Canyon 252#-01井钻至井深20,000 ft (1 ft = 0.305 m)，准备在8000多英尺井筒处打水泥塞，BP公司采用先替海……
