| 摘 要： | 腰英台油田区是松辽盆地南部近几年发现的具有超亿吨级储量规模的大型含油气区。结合勘探实践对腰英台地区青山口组油气成藏条件分析表明,油气成藏的主控因素包括烃源、储层和输导三个方面。油气成藏主要围绕乾安次凹生烃中心,烃源岩控制油藏的聚集与分布;断裂一方面作为输导体系,另一方面控制着不同类型油藏的平面分布;沉积微相控制砂体的平面分布以及砂体的储集物性。最终指出了近源带、断裂带、砂体发育带三者叠置区是下步勘探的有利方向。

| Abstract: | Yaoyingtai Oilfield is a big scale hydrocarbon region in the south of Songliao Basin discovered in recent years.According to analysis of hydrocarbon accumulation conditions in Qingshankou formation in Yaoyingtai region,major control factors of the formation of oil reservoirs includes source rocks,reservoir and migration.The oil reservoirs are mainly located around Qian’an sag which is the hydrocarbon generating center,and the accumulation and distribution of oil reservoirs is controlled by source rocks.Faults are not only the pathways for hydrocarbon migration,but also control the distribution of different types of oil reservoirs,and the distribution of sand body and reservoir physical properties are controlled by sediment microfacies.The main target for exploration of next step is the region near the hydrocarbon generating centers,faulted zone and sand body development zone. |
