摘要
随着世界海洋油气资源勘探开发水深的不断增加,海况环境变得更加复杂,钻井难度越来越大,对钻井工程提出了更高的要求。针对深水钻井面临的难点,对喷射下导管技术、动态压井技术、双梯度钻井技术以及微流量控制钻井技术等深水钻井技术进行了阐述,分析了各自特点和适用性,为国内海洋钻井设计和施工进一步走向深水提供指导。
More is required on drilling engineering and drilling technologies due to increasing water depth and complicated marine conditions.Based on the practice in deep water drilling both at home and abroad,some key technologies are discussed in this paper,the technology of jet type guide,the dynamic killing technology,the dual-gradient drilling technology and the micro flow control technology.The characteristics and applicability of all the technologies are analyzed,which play an important role in enabling drilling design and construction to further deeper water drilling.
