| 摘 要： | 在全球范围内，奥陶系海相地层都是重要的烃源层，且在国外研究颇多。近几年来，我国在以奥陶系为烃源层的油气勘探中取得了重要进展，如在塔里木盆地发现了一些主要源自下古生界，特别是奥陶系烃源层的油气藏。由于当时没有高等植物出现，因此奥陶系烃源岩在油气生成上与我国东部中、新生界陆相烃源岩有着明显的不同。本文通过对国内外奥陶系原油地化特征的研究，对涉及奥陶系油气生成的几个问题进行了讨论。同时希望能引起同行们对奥陶系油气生成的重视，从而使我国在台盆区的油气勘探中取得突破性的进展

| Abstract: | Marine Ordovician strata are an important hydrocarbon source in worldwide, and were studied bymany foreign workers.Now, oil and gas exploration for the Ordovician as a Source stratum has been ad-vanced for recent several years, for example, some oilfields have been found in Tarim Basin,of which oilsare from the Palaeozoic source, especially the Ordovician.The generation of hydrocarbons of the Ordovi-cian source is different from that of Mesozoic nd Cenozoic sources since there were on high plants in the Ordovician Period.In the article, several sapects on generation of hydrocarbons of the Ordovician sourcewere discussed base on geochemical features of Ordovician oilsin the world.And it is hoped that this dis-cussion may draw people' s attention to the generation of hydrocarbons of Ordovician strata. |
