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。

Abstract: Tidal flat deposit formed under dry and hot climate occurs in Carboniferous shale segment of Mangal sag in Tarim basin, in which Hade son 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 deposited 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.

Key words: Tarim basin, Mangal sag, Carboniferous, tidal flat, tide, sand sheet
