摘要

 During the Silurian, there was a relative flat and shallow marine basin of Tarim Basin, filling with clastic shoreline debris and delta system, which can been classified into 5 3th order sequences from bottom to top. The depositional sequence of Silurian in Tazhong and Tabei areas shows an obvious differential architecture, in which the 3th order sequeces of Kepingtage Formation (SQ-Skp₁, SQ-Skp₂ and SQ-Skp₃) developed well in Tabei area, filling with tidal flat, shallow marine mudstone,shoreline and delta systems. The tectonic evolution of Tazhong and Tabei areas controlled the development of sedimentary sequence and reservoir-seal combination. There is lack of the lower reservoir-seal combination in Tazhong area.
