Abstract:

The fluvial-delta-lacustrine depositional system develops for long in Chang 101 stage of Triassic Yanchang Formation in Ordos Basin. The sedimentary microfacies as braided channel and meandering channel of fluvial facies, braided subaqueous distributary channel, land distributary channel, subaqueous distributary channel and mouth bar of delta facies all develop sandstones. Based on the sedimentary facies study, the sedimentary characteristics of each sedimentary microfacies sandstone are deeply studied. The result shows that scour surface, trough cross-bedding, tabular cross-bedding and parallel bedding mainly developed in sandstone of braided channel, braided distributary channel and braided subaqueous distributary channel distributed in the west of the basin with fining-upwards normal cycle as the dominate feature. The grain-size probability curve of sandstone mostly has two steps or three steps. In the east of the basin, scour surface, trough cross-bedding, tabular cross-bedding, parallel bedding and sand bedding mainly developed in sandstone of meander channel, land distributary channel, subaqueous distributary channel and mouth bar with finingupwards normal cycle as the dominate feature while coarsening-upward inverse cycles can be recognized as well. The grain-size probability curve of sandstone mostly has two steps or three steps, moreover, four steps. Further comparative analysis indicates that sand bodies are mostly developed in braided channel, braided distributary channel, meandering channel and land distributary channel, followed by braided subaqueous distributary channel, subaqueous distributary channel and mouth bar in Chang 101stage.
