| 摘 要： | ＳＺ３６－１－１井碳酸协质砾岩段长期以来被划归东营组。在详细观察并分析岩心，岩屑的基础上，综合运用微体古生物，微量元素，粘土矿物和测井的资料，认为该砾岩段应划归上寒武统，其成因与黔东，湘西地区中，上寒武统碳酸盐重力流砾屑灰岩成因相似，应为深水斜坡上固结程度较差的薄层灰岩在重力作用下，形成具层流特征的粘性碎屑流缓慢进入泥质环境中，成为准同生碳酸盐质砾泥岩或碳酸盐质砾岩。

| Abstract: | The 1, 537-1, 654. 22 m interval which is mainly carbonate conglomerate at the well of SZ 36-1-1 has been divided intoDongying Formation for many years. Based on the examination of cores and cuttings and combined with the data ofmicrofossils, microeIements, thin sections, clay minerals and log analysis, the paper proposes that the 1, 537-1, 654' 22 minterval should belong to Upper Cambrian. The characteristic of this interval is similar to that of the calcirudites of carbonategravity flow in the Upper Cambrian in Qiandong and Xiangxi regions. .It is believed that they have the similar origin'Viscosity debris flow formed by unconsolidated thin bedding limestones on deep water sloped under gravitation, flew into amuddy environment where pe necontemporaneous carbonate gravel mudst ones or ca rbo na te congl ome rates formed. |
