辽河东部凹陷油燕沟潜山带石油地质条件研究

Research on Petroleum Geology of Youyangou Buried Hill in Eastern Liaohe Depression

以现有资料为基础,通过对区域构造、储层、烃源岩特征等基础石油地质条件的研究,认为油燕沟潜山发育中、古生界两套储层,中生界岩性以火成岩为主,古生界以碳酸盐岩为主。二界沟洼陷沙三中段暗色泥岩是本区的主要烃源岩,北东向驾掌寺断裂为主要油源断裂。潜山整体油气成藏条件优越,预测石油资源量约5000×104t,具有较好的勘探前景。

Based on available data, the study on regional structure, reservoir and source rock characteristics shows that it developed the Mesozoic and the Paleozoic reservoirs in Youyangou buried hill. The volcanic rock is the main reservoir in the Mesozoic and the carbonate rocks in the Paleozoic. The main source rock is the third member mudstones of Shahejie Formation in Erjiegou sag. Jiazhangsi fault Northeast trending played the roles of the faults connected with source rocks. There are superior hydrocarbon accumulation conditions and demonstrates preferable exploration prospect in the buried hill, which has about 5000 ×10^4t estimated petroleum resource.
