摘要: 综合利用地震、测井及测试资料对辽河滩海西部古近系油气输导体系进行了分析,认为古近系发育连通砂体、断裂及不整合3种油气输导基本要素,相互配合形成砂体-断裂、不整合-砂体、不整合-断裂及砂体-断裂-不整合4类油气输导组合样式,东部陡坡带以断裂-连通砂体-不整合输导体组合为主,输导类型主要为“S”型;西部斜坡区以连通砂体-断裂输导组合为主要油气运移通道,输导类型主要为阶梯型?平面上,断裂及“构造脊”是油气运移的主要路径,不同时期油气优势运移指向存在一定差别,总体来看,海南洼陷北部生成的油气主要向笔架岭地区及海南仙鹤地区运移,而南部次洼的油气主要指向葫东斜坡。

Abstract: This paper,based on seismic,logging,and assay data,analyzes the Paleogene hydrocarbon passage system in western Liaohe beach,concludes that three basic passage systems,connecting sandbodies,faults and unconformity, which comprise four combinations,sand-fault,unconformity-sand,unconformity-fault,and sand-fault-unconformity.Fault-sand-unconformity system dominates in the eastern steep slope displaying an”S”shape,sand-fault system in the western slope displaying a stage pattern.On plane,fault and structural ridge is a major path for oil-gas migration, which varies with periods.The hydrocarbon formed in the northern migrates to Bijialing and Xianhe areas,and that in the southern sub-depression migrates to Hudong slope.

Key words: passage system, hydrocarbon migration, Paleogene, Liaohe beach
