摘要
围绕中国大陆动力学基础地质研究的重大关键问题——板块汇聚边界的深部动力学、重要的矿产资源集聚区的成矿背景、成矿条件和深部找矿前景、盆山结合带对油气资源制约以及火山地质灾害预防等方面开展地质、地球物理研究、大比例尺地质调查科研填图和科学钻探选址预研究。在此基础上,运用不同技术方案在条件成熟的选区实施7口先导孔的科学钻探;开展“科学超深井钻探技术方案预研究”,提出一整套深孔和超深孔钻探技术方案;完成2~3个不同深度级别、不同应用场合及地层条件的科学钻孔的总体设计。
Geological and geophysical investigations and large-scale geological mapping will be carried out for site-selection of the pilot holes.The project is focusing on the key problems related to continental dynamics in China,such as deep dynamics along the convergent plate boundaries,geological background of major mineral resource regions,metallogenetic conditions and deep ore-prospecting,basin-range junction belt and its restriction on the formation of oil and gas resources,and prevention of volcanic disasters from a geological view.Seven 2000~3000 m deep pilot holes will be drilled for this new scientific drilling project,aimed at future site-selection of deep holes(over 10000 m deep)and preparation of deep drilling technique.Advanced techniques will be used for the 7 pilot holes and,on the basis of the achievements gained in“the pilot-research on deep scientific drilling technique”,two or three scientific drill sites with different depths,geological backgrounds and technical conditions will be designed for an integral plan of deep drilling in future.
