| 摘 要： | 辽河断陷以碳酸盐岩和砂页岩为主的古潜山地层一直全部划归中、新元古界。由于在该套地层的部分岩石薄片中发现交代残余的动物化石碎片，因此提出辽河断陷有古生界存在的新观点。通过牙形石、微古植物、动物化石和岩性组合的研究，对这套地层进行了重新厘定，建立了古生代寒武纪、奥陶纪、石炭纪和二叠纪地层层序。研究成果表明，辽河断陷存在古生界储层，古生代潜山并非单斜．而是由被断裂改造的褶皱组成的断块。这一成果为重新认识潜山的内幕构造特征和油气储层分布规律奠定了基础。 |

| Abstract: | The strata of buried hills in the Liaohe fault depression consist mainly of carbonate rocks and sandstone-shale, which were all assigned to the Meso- and Neoproterozoic. A new view of the existence of the Paleozoic in the Liaohe fault depression was put forward as residual animal fossil fragments were found in some rock sections from the strata. This succession of strata was redefined and the stratal sequence of the Cambrian, Ordovician, Carboniferous and Permian was established on the basis of a study of conodonts, microfloras, animal fossils and rock associations. The results of this study indicate that Paleozoic reservoir rocks exist in the Liaohe fault depression, and that the buried hills of the Liaohe fault depression are not a monocline but a complex faulted block composed of a part of a fold reworked by faults. The conclusion is a new basis on which a new knowledge of the structural features and hydrocarbon reservoir distribution characteristics of the Paleozoic inside the buried hills of the Liaohe fault depression may be gained. |
