摘　　要：在对川东南地区茅口组沉积背景认识的基础上,通过对野外剖面的详细观察,结合录井、测井资料,对岩性剖面结构进行细致分析,将其划分为3个三级层序。并从地质、测井方面,阐明了层序关键界面识别与划分的标志,认为茅口期相对海平面升降幅度不大,三个三级层序均为II型层序,在此基础上建立了川东南地区茅口组三级层序地层格架。Based on the knowledge of the sedimentary setting of the Maokou Formation in southeast area of Sichuan,with the outcrop observation,core log, electrical log,the author analysed the configuration of the lithological profile,and identified 3 third--order sequences. The signs for recognizing and dividing the key sequence interface in Maokou Formation were analyzed by using geology and log methods. After that, the author suspected that the sea--level change isn＇t obvious ,and every third-order sequence is Type II sequence. Finally, the third--order sequencesstratigraphic framework is established.
