摘　　要：塔里木盆地满加尔凹陷石炭系中泥岩段发育一套在干燥、炎热气候条件下形成的潮坪沉积。哈得逊地区由于其特殊的古隆起背景,高潮淹之,低潮露之,形成潮间坪沉积。在特大潮富砂期,古隆起上沉积厚度薄、面积大、连通好的砂席。砂席在潮汐和波浪的簸筛作用下,使其几何形态、厚度、物性特征均有改变。砂席是优质储集层,并且可能富含油。Tidal flat deposit formed under dry and hot climate occurs in Carboniferous shale segment of Mangal sag in Tarim basin,in which Hadeson area appears to be inter-tidal flat deposit for its particular old uplift setting that was submerged or come out depending on the high tide or low tide.During the super-tide with enriched sandstone,sand sheet with thin deposit,large area and better connection was de-posited on the old uplift.Under the winnowed and sieve processes,geometry,thickness and physical property of the sand sheet were all changed.It is believed that the sand sheet is a high quality of reservoir,and may contain enriched crude oil.
