摘要
Lower submember of the 8th of Middle Permain Shihezi Formation is quartz sandstone and lithic quartz-sandstone with higher compositional and textural maturity and light grey-white color, and is one of the main reservoirs in the basin with the thickness generally 15~40 m, tempesitites frequently occur in some well cores. According to thickness of single tempesitite bed,grain size, fragment contents of external land carbonaceous mudstone and coal, profile feature, especially the scale of hummocky crossbedding and pot cast,and more or less of the stacked tempesitites and so on, three ended type tempesitites could be divided approximately by varying degrees of energy stone wave current in cores.
