摘要
运用地震、测井等手段,结合岩石学、生物地层学地层对比方法,将塔里木盆地中—下奥陶统层序划分为1个二级层序(SSQ6),4个三级层序:SQ1、SQ2、SQ3、SQ4。对层序地层、沉积相特征研究发现,构造运动、海平面升降和古气候变化为塔里木盆地中—下奥陶统层序发育主要控制因素。
Dividing the sequence of Lower-middle Ordorician in Tarim basin by using seismic and logging,combining with the method of stratigraphic correlation based on lithostratigraphy, biostratigraphy.One second-order sequence（SSQ6）, four third-order sequences（SQ1, SQ2, SQ3, SQ4）have been distinguished in Lower-middle Ordorician,the features of sequence stratigraphy and facies are analyzed in this paper.The research shows that tectonic movement,sea level eustacy and paleoclimate are the major controlling factors about sequence evolution of Lower-middle Ordorician stratigraphic sequence,Tarim basin.
