探讨了库拜煤田下侏罗统塔里奇克组的聚煤特征与聚煤规律。据基础资料,采用层序地层、沉积体系等分析方法,建立塔里奇克组等时地层格架,分析层序格架下煤层发育及分布规律,总结塔里奇克组聚煤的层序地层学模式,预测煤炭资源时空分布。认为塔里奇克组可划分出两个三级层序,分别为SQ1、SQ2;煤层主要分布于SQ1、SQ2的湖扩和高位体系域;SQ1、SQ2中湖扩、高位体系域均有较连续煤层发育,湖扩体系域煤层好于高位体系域的。
The characteristics of coal accumulation and coal accumulation in the Tarim Basin in the Lower Jurassic in the Kibai coal field are discussed. According to the basic data, the sequence stratigraphy and sedimentary system are used to establish the isochronal stratigraphic framework, analyze the coal seam development and distribution under the sequence framework, and summarize the sequence of the Tarim Basin polymetallic coal Stratigraphic model to predict the temporal and spatial distribution of coal resources. It is believed that the Tarim Basin can be divided into two third-order sequences, which are SQ1 and SQ2 respectively. The coal seams are mainly distributed in the lacustrine and highstand system tract of SQ1 and SQ2. In the SQ1 and SQ2, The coal seams in the lake expansion system are better than the upper system tract in continuous coal seam development.
