摘　　要：渤海油田相关区块的首批开发井作业过程中普遍存在着下尾管困难等情况,直接影响了钻井时效,对海上油气开发带来了不利影响。介绍了渤海油田相关区块的首批开发井作业过程中尾管下入困难的原因,分析了机械偏心式随钻扩眼器技术应用的可能性。实践表明,机械偏心式随钻扩眼器的应用可以有效确保海上油田大位移钻井作业中的安全。Difficulties in lowering the tail pipe during the operation of the first development wells in the relevant blocks of the Bohai Sea oilfield are common,which directly affects the drilling time and has a negative impact on the offshore oil and gas development.The reasons for the difficulty in lowering the tail pipe in the first development wells in the Bohai oilfield are presented,and the possibility of applying the mechanical eccentric hole expander technology is analysed.It is shown that the application of mechanical eccentric follow-through hole expander can effectively ensure the safety of large displacement drilling operations in offshore oil fields.
