摘　　要：利用海上移动式平台开展钻修井作业,具有风险高、作业场地受限、逃救生难度大等特殊风险,冬季施工作业环境恶劣,井控风险、海上作业风险等多类风险叠加,一直是油气田及工程技术服务企业安全环保风险管控的重点,需要进行专门的风险评估,采取针对性防控措施。开展移动式钻修井平台冬季作业安全风险评估,需要充分掌握作业海域气象环境条件、平台技术参数等基础资料,辨识冬季钻修井作业特殊性的危害因素,分析低温条件下设备设施完整性和可靠性,检查安全管理制度、操作规程等的落实情况,评估平台结构抗冰性能、设备设施维护情况及外部资源等方面的风险,明确海上移动式钻修井平台冬季作业的基本安全条件,并提供风险管控措施建议。Drilling and workover operations are carried out using offshore mobile platforms,which has the special risks,such as high risk,limited working area,difficult to escape and rescue.The working environment is bad in winter,such as well control risk and offshore operation risk and other types of risks superimposed,which has always been focus of safety and environment risk management for oil and gas fields,engineering and technical service enterprises.It is necessary to conduct specialized risk assessment and take targeted prevention and control measures.To carry out the safety risk assessment of winter operation on drilling and workover platforms,the basic data such as the meteorological environment conditions of the operating sea area and the technical parameters of the platform need to be fully mastered.The hazard factors of the particularity of drilling and workover operations in winter need to be identified.The integrity and reliability of equipment and facilities under low temperature conditions need to be analyzed.The implementation of safety management system and operation regulations need to be checked.The ice resistance performance of platform structure,maintenance situation of equipment and facilities and external resources and other risks need to be evaluated.The basic safety conditions of winter operation on offshore mobile drilling and workover platforms need to be clarified,and suggestions on risk control measures also need to be provided.
