海洋地质十号船钻探系统及其在海洋地质调查中的应用

Drilling system on Marine Geology-10 Ship and its application in marine geological survey

摘要:

能源需求持续增长及环境污染防治、应对气候变化要求加快能源结构调整，迫切需要海洋地质调查工作为油气勘探开发提供新的靶区，为天然气水合物商业化勘查开发提供基础支撑。我国自主设计、建造的海洋地质十号船填补了我国小吨位大钻深海洋地质钻探船的空白，提升了海洋地质调查能力，也标志着我国海洋地质综合调查能力跻身世界前列，并为未来的大洋钻探提供了宝贵的经验。海洋地质十号船钻探系统针对不同地层采用不同的取心工具，顺利完成了南海某海域的钻探取心任务(A、B两个钻孔)。针对海洋钻探作业风险，制定的应对措施，保证了海洋地质十号船钻探作业的正常施工。实践证明，海洋地质十号船钻探系统可圆满完成了海洋地质钻探取心任务。

Abstract:

Continued growth in energy demand, prevention and control of environmental pollution, and response to climate change require accelerated energy structure adjustment. Marine geological surveys are urgently required to provide new target areas for oil and gas exploration and development, which provide basic support for the commercial exploration and development of natural gas hydrates. China’s independently designed and built Marine Geology-10 Ship fills the gaps in our country’s small tonnage and large deep marine geological drilling ships, which enhances our marine geological survey capabilities, and marks China’s comprehensive marine geological survey capabilities are among the best in the world and provides valuable experience for the future ocean drilling. The drilling system of Marine Geology-10 Ship uses different coring tools for different strata, and successfully completed drilling A and B holes for coring work in a South China Sea region. In view of the risks of marine drilling operations, the countermeasures formulated by Marine Geology-10 Ship have ensured the normal drilling operations. Practice has proved that the drilling system of Marine Geology〖KG-*8〗-〖KG-*8〗〖KG*9〗10 Ship successfully completed the coring work of marine geological drilling.
