Abstract

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.
