Abstract：A conglomerate reservoir bed, which, eroded,pinches out and overlies on the basalt reservoir,was discovered in Abei region of Erlian, Neimenggu.The middle section of the conglomerate reservoir has high r}si stivity and apparent negative spontaneous potential, The top and bottom of the conglomerate reservoir produce stronger and continuous reflections,but there is no reflection inside it.The reflections from the host conglomerate bed are in imbricate configuration,whose down dip direction indicates flow direction.The interval velocity of this conglomerate bed is 2，700-2，900 mjs.The interval velocity varies obviously in vertical and lateral directions, which means the change of lithofacies.Several isolated oil fields have been discovered in his region,and their reservoirs underlie the erosion surface and are controlled by the surface.It is obvious that Abei region may be a eroded unconformity oil bearing area.
