Drilling practices of deepwater well in West of South China Sea
南海西部海域W区块的深水钻井作业中，低温高压和狭窄的安全密度窗口给钻井工程带来了较大的困难，容易引起井漏、溢流、环空带压、生成水合物等问题，且附近海域经常出现由内波流引起的突发性强流。针对这些问题，结合W区块的钻井地质特征，开展了深水井井身结构优化技术、随钻扩眼技术、深水井钻井液防水合物及防漏堵漏技术、环空压力预测与管理技术、内波流应对技术等方面的研究，解决了深水钻井容易发生的井漏与溢流并存、水合物堵塞管线、环空压力高和内波流损坏水下设备等问题，…查看全部>>
During the deepwater drilling operation of W block in the sea areas in the west of South China Sea, the low-temperature, high-pressure and narrow safety density window has brought about great dififculties to the drilling engineering, and may easily lead to lost circulation, overlfow, annular pressure, hydrate generation and other problems, and the sudden strong current arising from the internal wave current frequently occurs in the nearby sea areas. Based on…查看全部>>
