| 中文摘要:随着渤海油田开发的深入，深井、大位移井等高难度井作业大量增加，为保证安全，在井内下入尾管或者完井时下入防砂筛管等成为必然要求。但这类作业一般处于井的深部井段，实施困难较大，为保证尾管、筛管的顺利下入，利用扩眼器将实际井眼扩大成为解决问题的主要技术措施。介绍了单球投入式扩眼器的结构组成及工作原理，并通过实例阐述了该扩眼器在随钻扩眼、钻后扩眼（倒划扩眼、下划扩眼）的应用情况，对扩眼器在不同工作模式下的使用效果进行了分析。 |

| Abstract:Along with the development of Bohai oilfield, deep wells, extended-reach wells and some other high difficulty wells operation are greatly increasing. It is an inevitable requirement to run liner into the well or land sand screen after well completion. But this operation is generally carried out in deep well section with great difficulty, reaming becomes the main technical measure. The paper introduces the landed single ball reamer about its structure composition and working principle, elaborates the application in reaming while drilling and reaming after drilling (back reaming and underreaming) with example and analyzes the application effects in different operation models. |
