塔里木盆地哈德1井区石炭系下泥岩段地层及沉积相研究

Strata and Sedimentary Fades of Lower Mudstone Section in Carboniferous System of Well Hade 1 in Tarim Basin

从岩性、电性及古生物分布等方面着手,深入探讨了塔里木盆地哈德1井区石炭系下泥岩段的地层归属问题,并与邻区进行对比,证明哈德地区下泥岩段应与其邻区下泥岩段砂泥岩层的层位相当。在此基础上,对该地层的层序特征、沉积相展布及储层物性分布作了详细描述,并指出了进一步勘探的方向。

From the aspects of lithology and electric property and distribution of paleontology, stratigraphic subsumption of lower mudstone section in carboniferous system of Well Hade 1 is deeply studied and compared with that of adjacent area. It is proven that the lower mudstone section in the well area is equivalent with the sand-shale level in the lower mudstone section of the adjacent area. On the basis of the study , sequence stratigraphy, distribution of sedimentary facies and distribution of reservoir physical properties are described in detail, by which direction is pointed out for further exploration.
