摘要：

松辽南部早白垩世断陷期地层地震相分析显示,该时期冲积扇、三角洲、水下扇及扇三角洲沉积体系十分发育,是深部油(气)聚集的有利场所。登娄库组可分出:浅埋弱压实成岩相、晚表生溶蚀成岩相、深埋溶蚀成岩相、深埋压溶成岩相,以前二者为油气聚集的有利成岩相。

关键词: 断陷期, 沉积相, 地震相, 成岩作用, 成岩相

Abstract:

The seismic analysis of the Early Cretaceous fault-subsidence stage in South Songliao Basin suggests that the depositional system including alluvial fan-delta, subaqueous fan, delta and fan-delta developed well, and they are favourable for oil and gas accumulation. The Denglouku Formation in the study area could be divided into shallow buried-weak compacted diagenetic factes,supergene dissolution diagenetic factes, deep-buried dissolution diagenetic factes and deep-buried compaction-dissolution diagenetic factes. The first two kinds are favourble factes for hydrocarbon accumulation.
