17(H)-diahopane are extensively distributed in Yanchang formation source rocks of Ordos Basin, but the content varies greatly. The content of 17(H)-diahopane is pretty low in Chang 7 oil shale, whereas it is very high in Chang 9 mudstones. Low diahopane abundance of Chang 8(1) reservoir extracts and similar crossplots of Ts/C29Ts and C-30 diahopane/C-30 hopane show that Chang 8(1) oils come from Chang 7 oil shale. However, Chang 8(2) and Chang 9 reservoir extracts are similar to Chang 9 source rocks in most of geochemical parameters, which indicates that the oil is derived from Chang 9 source rocks.
