摘要: 本文在对现代洪积的野外考察萎础上,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一孔隙结构的双重介质。

Abstract: 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 as the distribution of interbeded layers and barriers, in Karamay oilfield.The author concluded that the sandconglo-inerate reservoirs located at apex of alluvial fan is a non-typical dual medjum with fracture--pore tex(ure features.
