随着世界深水油气资源不断发现,近几年来深水钻探工作量越来越大。随着水深的增加和复杂的海况环境条件,对钻井工程提出了更高的挑战,钻井技术的难度越来越大。从目前国内外深水钻井实践出发,对深水的钻井设备、定位系统、井身结构设计、双梯度钻井技术、喷射下导管技术、动态压井钻井技术、随钻环空压力监测、钻井液和固井工艺技术和钻井隔水管及防喷器系统等关键技术进行了阐述,对深水的钻井设计和施工进一步向深水钻井领域发展具有重要导向作用。
As more and more oil and gas resources are discovered in deepwater worldwide, the deep water drilling has become more and more in recent years. It requires more on drilling engineering and drilling technologies due to the increased 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, including the drilling equipment, the positioning system, the casing program design, the dual-gradient drilling technology, the technology of jetting and lower circuit, the dynamic killing and drilling technology, the technology of annulus pressure detection while drilling, the technology of drilling fluid and cementing, the drilling raiser technology, and the blowout preventer system. All the technologies play an important role in enabling drilling design and construction to expand into deep water.
