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.

Key words: alluvial fan reservoir, sedimentary characteristic, continuity, high-permeability network, flow mecha-nism
