摘要： 通过分析若参 1 井岩心、录井、测井资料,结合新的地震资料解释成果,对塔东南坳陷侏罗系各组沉积特征及其沉积相展布进行了详细研究,并探讨了沉积相变化与构造演化之间的关系。认为若羌凹陷早-中侏罗世是断陷盆地,早侏罗世发育冲积扇和辫状河三角洲,中侏罗世以辫状河三角洲和湖泊沉积为主;晚侏罗世演变为坳陷盆地,以河流沉积为主。若羌构造带和民南构造带是较有利的油气勘探区带。

Abstract: Based on the core, logging and well log data, integrated with available seismic interpretation results, in-depth study of sedimentary characteristics and sedimentary facies distribution of Jurassic in southeast depression of Tarim basin is made, including the relations between sedimentary facies variation and tectonic evolution. The study shows that in Early-Middle Jurassic, Ruoqiang sag was a fault basin with alluvial fan and braided river delta deposits in Early Jurassic, braided river delta and lacustrine deposits in Middle Jurassic; in Late Jurassic, it became a downwarping basin dominated by fluvial deposit. Ruoqiang structural belt and Minnan structural belt are favorable areas for petroleum exploration

Key words: Tarim basin, southeast depression, Jurassic, sedimentary feature, tectonic/structural evolution
