摘要
塔里木盆地东北部上震旦统—下古生界经历了漫长的沉积演化过程,是一套巨厚的以碎屑岩为主的沉积。根据该区露头、地震资料,结合钻井信息,应用层序地层学理论,对该套地层的沉积演化史进行了分析,认为该区上震旦统—下古生界存在四个不整合面和二个可能的不整合界面,据此可将这套地层划分出5个三级层序,4套完整的生、储、盖组合
Upper Sinian-Paleozoic in northeastern Tarim baisn, which takes a set of thick
    clastic rock as the main sediments, underwent a very long period of sedimentation and
    evolution. Based on outcrop, seismic and drilling data, by the means of the sequence
    stratigraphy theory, the sedimentary evolution history of these strata was analyzed. It is
    considered that there are four unconformable surfaces and two probable unconformable
    surfaces in Upper Sinian-Paleozoic, and moreover, these strata can be divided into five
    microsequences, in which four sets of sourcereservoir caprock assemblages were developed.
