摘　　要：深水钻井具有高风险、高技术和高投入的特点。介绍了深水钻井中的主要风险，包括：恶劣环境、浅层气、浅层水流动、天然气水合物、不稳定海床、狭窄压力窗口引起的井喷或井漏、远距离后勤支持等。对深水钻井风险进行了分析评估，并根据评估结果给出应对策略。研究结论对深水钻井作业风险控制具有实用意义。High-risk, high-tech and high investment are specific characteristics of deepwater drilling. In this paper, main risks of deepwater drilling are introduced and classified, such as harsh environment, shallow gas, shallow water flow, gas hydrates, unstable seabed, well blowout or well loss caused by narrow pressure window, and long-range logistical support. Furthermore, deepwater drilling risks are analyzed respectively. Finally, according to the assessment results, some practical and functional risk control measures are put forward, which are potentially useful in the field of deepwater drilling.
