曾母盆地为一非典型的前陆盆地,盆地的类型决定了地层沉积模式,同时也决定了含油气盆地成藏的基本条件。盆地内多旋回的持续沉降形成了多套有利的生储盖组合,包括区域生储盖组合和各层序内的生储盖组合。相区在空间的分布具有三分性,最有利的含油相带区为西部台地—碎屑岩混合相区、南部碎屑岩相区和北部台地相区,优越的构造岩相带使其具备了形成大型油气田的基本条件。
The Zengmu Basin is an atypical foreland basin. The type of the basin determines the sedimentary model of the formation and also determines the basic conditions for hydrocarbon accumulation in the petroliferous basin. Multiple cycles of subsidence in the basin have resulted in the formation of several favorable reservoir-cap assemblages, including the regional reservoir-cap combination and the reservoir-cap combination within each sequence. The distribution of facies in the space has a trisection. The most favorable oil-bearing facies belts are the western Taiwan-clastic mixed facies, the southern clastic facies and the northern Taiwan terraces, and the superior tectonic facies belt The basic conditions for the formation of large oil and gas fields.
