摘要： 通过对塔里木盆地北部寒武系的层序关键界面识别、层序延续时间分析、沉积相划分、地层叠置结构分析，以三级层序为单元勾绘了其台地边缘相带的展布，明确了其有利勘探区。研究结果表明：①塔里木盆地北部寒武系可识别出10个三级层序，自下而上为SQ1—SQ10，下寒武统SQ1—SQ2时期发育缓坡沉积，为Ⅰ型层序； SQ3—SQ5时期发育缓坡型碳酸盐岩台地，均为Ⅱ型层序；中寒武统SQ6时期发育碳酸盐岩台地，为Ⅱ型层序；中上寒武统SQ7—SQ10时期发育碳酸盐岩镶边台地，SQ7和SQ9为Ⅰ型层序，SQ8和SQ10为Ⅱ型层序。②研究区SQ3层序的台地边缘相带分布范围广，在柯坪隆起—沙雅隆起一线呈近东西向展布，自沙雅隆起—顺托果勒近南北向展布； SQ4—SQ10台缘相带主要呈近南北向展布，具有较好的继承性，台地边缘不断向斜坡—盆地推进，有明显的前积特征； SQ3—SQ10时期台缘高能礁滩相带展布较宽，台缘礁滩相储层面积大。③研究区塔深2井以东呈南北向延伸的台缘相带是储层发育的有利区带，与寒武系主烃源岩具备良好的空间配置关系，为最有利的勘探区带。

Abstract: Based on the identification of key sequence boundaries，analysis of sequence duration，sedimentary facies division and analysis of stratigraphic superposition structure of Cambrian in northern Tarim Basin， the distribution of platform margin belt was sketched out with the third-order sequence as a unit， and its favorable exploration areas were defined. The results show that： （1）Ten third-order sequences were identified in the Cambrian strata in the northern Tarim Basin，and they were numbered from SQ1 to SQ10 from bottom to top. Gentle slope sediments are developed in the SQ1-SQ2 period of the Lower Cambrian， which are type Ⅰ sequences. In SQ3- SQ5 period，carbonate platforms of gentle slope are developed，which are type Ⅱ sequences. Carbonate platforms are developed in SQ6 period of Middle Cambrian，which are type Ⅱ sequences. Carbonate rimmed platforms are developed during SQ7- SQ10 period of Middle and Upper Cambrian. SQ 7 and SQ 9 are type Ⅰsequences，and SQ8 and SQ10 are type Ⅱ sequences.（2）The platform margin facies belt of SQ3 sequence in the study area shows wide spatial distribution. It is distributed along Keping uplift to Shaya uplift in near EW direction，and along Shaya uplift to Shuntuoguole uplift in near N-S direction. The platform margin facies belt of SQ4-SQ10 is distributed along N-S direction， showing good successive development characteristics， with the platform margin pushing towards the slope-basin area and displaying clear progradation pattern. High-energy reef shoal facies belt of SQ3-SQ10 is widely distributed， and the reef shoal facies reservoir area on the platform margin is large.（3）The platform margin facies belt in the study area extending in the N-S direction，located in the east of well TS2，is the most favorable zone for reservoir development. It is also the most favorable exploration area because of its good spatial relationship with Cambrian main source rocks.

Key words: third-order sequence, sequence stratigraphic framework, carbonate rock, tidal flat facies, reef shoal facies, lagoon facies, platform margin belt, Cambrian, northern Tarim Basin
