| 摘 要： | 岩心分析和测井标定综合分析表明,辽河滩海西部凹陷发育沙三段和沙一二段两套有效烃源岩,主要分布在海南洼陷带。油气输导层主要由断裂(带)、连通的砂砾岩体和不整合面构成,它们或单独、或组合,控制着主要油气富集带的油气输导及聚集成藏。复合圈闭带控制着复合油气聚集带的形成,各复合油气聚集带的成藏条件相互匹配,形成特征油气成藏模式和油气分布规律。

| Abstract: | Hydrocarbon in the West Sag of Tanhai area, the Liaohe Basin was mainly derived from the source rocks of the Es~3 and Es~(1 2) Member. By integrating the methods of well core analyzing and logging calibrating, the effective thickness of source rocks and their distribution were determined. Faults, connec-ting sandstones and unconformities were the three main pathways of petroleum migration in the study area. They singly, or combined with others, controlled the migration and accumulation of oil and gas around main hydrocarbon-bearing zones. Moreover, composite trap zones led to the formation of composite hydrocarbon accumulation zones. Hydrocarbon pool-forming conditions matched with each other, and formed characteristic accumulation models and distribution rules in every composite hydrocarbon accumulation zone. The distribution of oil and gas was clarified for guiding the future petroleum exploration of the area. |
