针对巴彦乌拉地区赛汉组沉积微相的电测井响应特征进行分析,并分析该地区的沉积微相特征. 结果表明,巴彦乌拉地区的赛汉组属于辫状河沉积,河道砂体发育,单层砂体及多期河道叠置砂体厚度大,砂岩胶结物少,连通性和渗透性好,是良好的铀矿目的层.但由于泛滥平原微相不太发育,泥岩在局部地段薄,对形成理想的砂泥结构不利.

This paper analysises the electrical logging response features of sedimentary microfacies and the sedimentary environment of Saihan formation in Bayanwula area. The results show that Saihan formation is the sediment of braided river, sandbodies of the single and superimposed channel in the formation are of thick depth and good connectivity and permeability which are very favorite for uranium minerallization. But perfect mudstone-sandstone-mudstone structure was not well developed due to the thin mudstone of juvenile flood plain.
