摘要
古生代放射虫硅岩地层中富含浮游相的微体生物化石,这些化石中的脂类物质和有机质在地层中往往形成海相烃源岩而富含油气资源。这类地层的油田已在北极加拿大、美国、澳大利亚和俄罗斯等地发现,特别是俄罗斯的Domanik层(上泥盆统)是目前正在开采的世界上最有名的顶级大油田。我国西南地区的云南、贵州和广西等省区有与世界级大油田相似的古生代放射虫硅岩地层,但在过去的勘探中这类地层从未列入勘探目标,我们相信,在不久的将来,这类地层将成为一个潜在的油气勘探目标。
Paleozoic radiolarian cherty strata contain abundant planktic microfossils which provide rich lipid and organic materials commonly associated with marine hydrocarbon source rocks rich in oil and gas. This type of oil fields has been found in the Canadian Arctic, America, Australia and Russia; especially, Upper Devonian Domanik Horizon of Russia is a famous major oil field recovered at present. Paleozoic radiolarian cherty strata similar with those of the above mentioned major oil fields have been developed in Yunnan, Guizhou and Guangxi, Southwestern China. Although these strata have never previously been used as the target for oil and gas exploration, we believe that they will make such a potential target in not too distant future.
