| 摘 要： | 通过对东南亚主要含油气盆地沉积、构造特征的研究，揭示其烃源岩具有多期发育的特点.其中，始新统、渐新统和中新统是东南亚主要的3套烃源岩；前新生代生油岩分布局限，但具有一定的生烃潜力.以新生代河流-三角洲近岸沉积环境、含陆源干酪根的煤系和碳质页(泥)岩为主，其次为湖相和海相沉积环境泥岩和页岩.有机碳含量均已达到中等-好的源岩标准，以Ⅱ-Ⅲ型干酪根为主，大部分烃源岩都处于成熟到过成熟阶段.新生代烃源岩主要受盆地演化阶段和沉积环境两大地质因素控制，与区域海侵作用的方向和规模密切相关.烃源岩有机质类型的不同和热演化程度的差异，是形成东南亚地区多类型油气藏的重要因素之一.

| Abstract: | Based on the research of the sedimentary and structural features, hydrocarbon source rocks in the main sedimentary basins in Southeast Asia can be defined into multi-phases and those in Miocene, Oligocene and Eocene are the most important three sets. The pre-Cenozoic source rocks have certain potentials, but with limited distribution. The three sets are mainly fluvial facies to paralic delta with terrigenous kerogen-based coal and carbonaceous shale (mudstone), followed by lacustrine and marine depositional including mudstone and shale. The total organic carbon in these rocks has reached to intermediate to good dominated by Ⅱ-Ⅲ type of kerogen, and most of them are in the stage of mature to over-mature. The generation and distribution of the source rocks are mainly controlled by two geological factors, namely, tectonic evolution and depositional environments of the basins, and closely related to the direction and scale of regional transgression. Therefore, the fractionations in the type and the thermal evolution degree of hydrocarbon source rocks are the most important factors contributing to the various types of oil and gas reservoirs in Southeast Asia. |
