单筒三井技术在涠洲6-1油田的应用

单筒三井技术在国内首次应用于海上油田开发,不仅如此,涠洲6-1油田的开发难度与世界其他单筒三井的应用相比难度也较大。结合涠洲6-1油田的实际情况,系统阐述了单筒三井技术的工艺特点,介绍了单筒三井相关的重要技术,即单筒三井井口技术、表层钻进技术、表层套管的下入要点以及表层固井作业等。涠洲6-1油田单筒三井技术的成功应用是一个重大的突破,为今后同类井的应用积累了宝贵的作业经验。

Application of three-in-one drilling technology in Weizhou6-1 oilfield

Weizhou6-1 oilfield applies three-in-one technology for the development of ocean oilfield as the first one in domestic.Moreover,the application of three-in-one technology in the oilfield is more difficult than that in other oilfield in world.According to actual conditions of Weizhou6-1 oilfield,process features of three-in-one technology are systematically described,meantime,many most important elements such as three-in-one wellhead technology,surface drilling technology,main points of surface casing running in,surface cementing operation,and so on are introduced.Successful application of three-in-one technology of Weizhou6-1 is a significant breakthrough,offering some precious operation experience for such wells in future.
