摘要：

通过系统总结柴达木盆地“十二五”以来主要勘探发现和重要地质认识，提出了盆地未来油气勘探从浅层向深浅层结合、从构造向构造—岩性结合、从碎屑岩向多种岩性复合、从常规向常规与非常规结合的四大转变。系统分析盆地四大含油气系统，结合成藏主控要素，按照战略准备、战略突破和战略展开3个层次，共梳理出13个有利油气勘探方向和3个非油气矿产的勘探方向，系统梳理柴达木盆地油气勘探地质、工程技术、管理等方面面临的主要挑战并提出对策，为推动柴达木盆地油气勘探转型发展、强改造型盆地油气地质理论技术提升和盆地综合资源勘探持续发现提供支撑。

Abstract: The major discoveries and geological understanding in petroleum exploration since the 12^th Five-Year Plan period are summarized in detail. Four major changes are proposed for future petroleum exploration, i.e., from shallow formation to both deep and shallow formations, from structural to structural-lithologic traps, from clastic rock to multi-lithologic composite reservoir, and from conventional to both conventional and unconventional oil and gas reservoirs. Based on the systematic analysis of the four major petroleum systems in the basin, and combined with the main controlling factors for hydrocarbon accumulation, a total of 13 favorable oil and gas exploration orientations and 3 types of non-oil and gas minerals are identified in Qaidam Basin as in three levels of strategic preparation, strategic breakthrough and strategic deployment. In addition, the main challenges in geology, engineering technology, and management restricting petroleum exploration are systematically summarized and countermeasures are put forward, which provide support for promoting the transformation and development of petroleum exploration, improving petroleum geological theory and technology of strongly transformed basin and the continuous discovery of comprehensive resources in Qaidam Basin.
