摘要
本文在对现代洪积扇的野外考察基础上,对克拉玛依油田井下三叠系洪积扇砂砾岩体的分布形态、宏观连续性及夹层、隔层分布进行了详细的描述。作者认为洪积扇扇顶砂砾岩储层是一种非典型的具有裂缝—孔隙结构的双重介质。
Based on field investigations of recent alluvial fan bodies,detailed descriptions are made in this paper on their dis-tributing forms and macroscopic continuity of subground Triassic alluvial fan's sand-conglomerate bodies as well asthe distribution of interbeded layers and barriers ,in Karamay oilfield. The author concluded that the sand-conglo -merate reservoirs located at apex of alluvial fan is a non-typical dual medium with fracture-pore texture features.
