摘要： 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。

Abstract: The accumulation characteristics and distribution rules of marine hydrocarbon source materials as foundations for hydrocarbon accumulation are extremely important and basic geologic conditions for exploration, which are elaborated in terms of hydrocarbon- generating material, hydrocarbon-storing material and hydrocarbon-sealing material for forming the marine hydrocarbons. The distribution of marine hydrocarbon-generating material is closely related to the changes of paleo-structure, paleo-sedimentary environment, paleo- climate and paleo-ocean. The developed horizons or levels always appear in transform stages of significant changes of tectonic framework and sedimentary basin in nature, with close relations to the global anoxic events. The distribution of marine hydrocarbon-storing material is mainly controlled by sedimentation, diagenesis and tectonic movement. The distribution of premium reservoir is commonly and closely related to low-level system tract and late high-level system tract in terms of second-class sea level change. The distribution of marine hydrocarbon-sealing material is coincident to that of marine regional source rocks, but the former is more plentiful than the latter in type.

Key words: marine hydrocarbon, material accumulation, hydrocarbon-generating material, hydrocarbon-storing material, hydrocarbon-sealing material
