塔里木盆地古隆1井奥陶系恰尔巴克组与一间房组的发现及意义
|
摘要
塔里木盆地古城墟隆起古隆1井首次发现了上奥陶统恰尔巴克组及中奥陶统一间房组,其具有与命名剖面、塔河及沙西地区典型钻井剖面基本一致的岩性组合、电性特征及牙形石带,且其地层层序结构独特。岩石学、沉积构造及古生物群面貌均反映出恰尔巴克组属于斜坡相沉积。地震剖面资料显示恰尔巴克组与一间房组在古城墟隆起西段分布较稳定,且易于追踪对比。其主要分布在隆起边缘的低洼部位及斜坡相的过渡区;在隆起的主体上,分别为沉积缺失与剥蚀缺失。这些发现为古城墟隆起、卡塔克隆起、塘古巴斯凹陷、塔河及沙西地区奥陶系的划分对比、沉积环境及构造运动的分析创造了条件。
The Qrebake Formation of the Upper Ordovician and the Yijianfang Formation of the Middle Ordovician have been found for the first time in well GL1 of the Guchengxü Uplift of the Tarim Basin.They have the same lithologic association,electrical property and conodont zone as name-sections and typical wells in the Tahe and Shaxi regions.Unique stratigraphic sequence has been found in the study region.According to studies of petrology,sedimentary structure and palaeontology,the Qrebake Formation belongs to slope facies sediments.The Qrebake and the Yijianfang Formations distribute stably in the west of Guchengxü Uplift and are favorable for trace comparison on seismic profiles.The 2 formations mainly locate in the lower positions of uplift margin and the intermediate zone of slope.On the uplift,sedimentary gap and degradation vacuity are found respectively.The studies may help the stratigraphic correlation of Ordovician and the analyses of sedimentary environment and tectonic movement in the Guchengxü Uplift,the Katkke uplift,the Tangusbas Sag,and the Tahe and Shaxi regions.
