摘要: 日本地区主要的含油气盆地为典型的弧前盆地和弧后盆地,其主要受太平洋板块、北美板块、菲律宾海板块以及欧亚板块构造运动的共同影响,作用时间长,地质构造复杂。通过对日本地区主要含油气盆地的大地构造背景、沉积特征及油气田开发数据等进行研究,表明研究区盆地构造演化经历俯冲期、盆地发育期、沉降期和挤压变形期4个阶段,其中沉降期为新近纪中新世,是油气生成的关键时期。目前已发现油气主要赋存于以构造圈闭、岩性圈闭及复合圈闭为主的新近纪地层中,同时前新近系基底裂缝性储层油气亦较为丰富,平面上油气分布呈现出明显的零星式分布,且纵向上油气分布呈现出明显的不均一性。研究区存在三大油气成藏模式,即垂向运移-断裂通道式、侧向运移-斜坡通道式和自生自储式,且以垂向运移成藏模式为主。以成藏组合为评价单元,对研究区含油气盆地8个成藏组合进行油气资源潜力分析,表明新泻盆地、关东盆地、庆尚盆地和北上盆地是日本地区未来主要的油气勘探区。

Abstract: The principal petroliferous basins in Japan are typical fore-arc basins and back-arc basins. They have complex geological structures that were formed under the joint effects of the tectonic movements of Pacifc Plate, North America Plate, Philippine Sea Plate and Eurasian Plate for a long time. In this paper, these principal petroliferous basins were investigated from the aspects of tectonic setting, sedimentary characteristics and development data. It is shown that the structural evolution of these basins can be divided into four stages, i.e., subduction, basin development, subsidence and compression deformation. The subsidence stage in the Miocene of Neogene is the key period for hydrocarbon generation. The oil and gas discovered are mainly preserved in structural traps, lithologic traps and complex traps of Neogene, as well as the basal fractured reservoirs of pre-Neogene. The oil and gas are horizontally scattered and vertically inhomogeneously distributed. The hydrocarbons in the study area were mainly accumulated in three patterns, i.e., vertical migration-fracture pathway, lateral migration-slope pathway, and self generation-self preservation, with the predominance of vertical migration hydrocarbon accumulation. Plays were taken as evaluation units. Eight plays in the petroliferous basins of the study area were analyzed from the aspect of resource potential. It is indicated that the Niigata Basin, the Kanto Basin, the Gyeongs Basin and the Kitakami Basin are the major oil and gas exploration areas within Japan in the future.
