全球常规类大型、特大型油气田主要分布在特提斯域、被动陆缘、前陆冲断带和克拉通等盆地中.非常规类油气田主要分布于前渊斜坡、盆地(坳陷)中心、克拉通向斜区和冻土带等.21世纪以来全球油气勘探重大发现主要集中在被动陆缘深水区、碳酸盐岩、岩性一地层、前陆冲断带、成熟探区、新地区新盆地及非常规油气藏(场)等7大领域.这些重大发现涉及油气勘探中的常规与非常规2类油气资源.常规石油地质强调在单一明确圈闭中的油气运聚和成藏规律;非常规石油地质重点研究非常规资源、非常规储集层、非常规成藏与非常规技术等.非常规油气藏(场)在地质特征、分类方案、研究内容、评价方法和勘探阶段等方面与常规油气藏有明显不同.需要加强非常规石油地质研究,发展非常规石油地质理论.

Large and extra-large oil/gas fields are mainly distributed in Thews areas, passive margins, foreland thrust belts, and craton basins in the world. Unconventional oil/gas fields are mainly distributed in foreland slopes, basin (depression) centers, craton synclines, and tundras. Since the 21~(st) century, the major exploration discoveries across the globe have been mainly concentrated in the deep water area of passive margins, carbonate rock, lithologic-stratigraphic zone, foreland thrust belt, mature exploration area, new basin and unconventional oil/gas reservoir (field). These major discoveries involve conventional and unconventional oil/gas resources. The conventional oil geology stresses the oil/gas migration and reservoir-forming rules in individual traps;the unconventional oil geology focuses on unconventional resource, reservoir, reservoir-formation and technologies. The geological features, classification program, research content, evaluation method and exploration phase of unconventional oil/gas reservoirs (fields) are different from those of conventional ones. Research should be strengthened on unconventional oil geology to develop unconventional oil geological theories.
