| 摘 要： | 在总结二连盆地马尼特坳陷伊和勘查区钻遇地层与烃源岩发育特征的基础上,通过对揭示二叠系的钻井油气显示与油气层测试情况,以及对不同井区原油物性与地球化学特征的分析,认为YH3井天然气、YH8井区轻质原油与中生界烃源岩无关,探讨了与石炭系—二叠系烃源岩有关的油气赋存信息,为二连盆地石炭系—二叠系油气地质调查与勘探提供重要信息。

| Abstract: | Based on comprehensive understanding upon the drilling strata and the characteristics of hydrocarbon source rocks of Yihe exploration area in Manit depression of Erlian basin, hydrocarbon exploration potential of this basin has received large attention in recent years. This paper provides Permian hydrocarbon information from well-drilling data and hydrocarbon reservoir test, combined with comparative analysis of crude oil physical properties and geochemical characteristics between different well areas. It indicates that the natural gas obtained from the Well YH3 and the light crude from the Well YH8 has nothing to do with Mesozoic hydrocarbon source rocks. Besides, this paper discusses the information of hydrocarbon occurrence which is related to Carboniferous- Permian source rocks, thus providing an important clue in response to geological survey and exploration for Carboniferous-Permian hydrocarbon resources in Erlian basin. |
