从海相油气形成的生烃物质、储烃物质和封烃物质3个方面,阐述这些物质的聚集特征和分布规律。海相生烃物质的分布与古构造、古沉积环境、古气候、古海洋等变化密切相关,其发育层位总是出现于大地构造格局、沉积盆地性质发生重大变革的转换期,在产出层位上与全球性缺氧事件紧密联系;海相储烃物质的分布主要受沉积、成岩、构造3种作用的控制,优质储集层的分布通常与二级海平面变化的低水位体系域和高水位体系域后期密切相关;海相封烃物质的分布与海相区域烃源层的分布基本一致,但它的类型要比区域烃源层丰富。
From the three aspects of hydrocarbon generation, hydrocarbon storage and sealing hydrocarbon formed by marine oil and gas, the characteristics of aggregation and distribution of these substances are expounded. The distribution of marine hydrocarbon-generating substances is closely related to paleostratigraphy, palaeo-sedimentary environment, paleoclimate and paleoceannorm. The developmental stratum always appears in the tectonic framework, and the sedimentary basin undergoes the transformation of major transformation. In the output layer Which is closely related to the global anoxic event. The distribution of marine hydrocarbon reservoirs is mainly controlled by three functions of sedimentation, diagenesis and tectonics. The distribution of high-quality reservoirs is usually related to the low level system tract The distribution of marine sealing hydrocarbons is basically the same as the distribution of hydrocarbon source zones in marine areas, but its type is more abundant than the hydrocarbon source in the area.
