| 摘 要： | 塔里木盆地北部震旦纪－古生代层序地层格架中，发育着６个可作为生油层的大型密集段或复合密集段。密集段在层序格架中有４种叠置型式，即进积组合，退积组合，加积组合和上超组合。不同的叠置型对应于不同的海平面变化过程。相应地，密集段的发育规模及时空展布有着明显的差别，其中，在退积层序组合和进积层序组合中，密集段垂向上相互叠置，侧向上彼此邻接，构成层数与厚度复杂多变的复合密集段，是盆地中的主力生油层。

| Abstract: | According to the analysis of sequence stratigraphy,six condensed sections or compo_ site condensed sections, which correspond to source rocks, can be identified in Sinian-Paleozoic of North Tarim Basin. Four types of superposition patterns of condensed sections exist in sequence stratigraphic framework, that is, transgression, regression, aggradation and onlap associations. The different types of stacking patterns reflect different processes of sea level changes, corresponding, the thickness and distribution regularities of condensed sections are evidently different. The composite condensed sections stacked vertically and linked laterally in regression and transgression associations are main source rocks in North Tarim Basin. |
