Abstract: The tectono-sedimentary differentiation through geologic history has an important influence on the tectonicsedimentary filling processes of the carbonate strata and the geological conditions for hydrocarbon accumulation in large petroliferous basins. Through the high-density 2D seismic data and logging-drilling data covering the whole area，the uplift and sag patterns and paleogeographic evolution of eastern Sichuan Basin during the depositional period of Triassic Jialingjiang Formation were described in detail. The results show that: (1) Linshui-Fengdu intra-platform depression was identified from the characteristics of seismic section，stratigraphic and lithological combination. Its slope is about 1°-2°，and the slope on the left is greater than the slope on the right. (2) LinshuiFengdu intra-platform depression and other paleogeological units jointly controlled the paleogeographic pattern and tectono-sedimentary differentiation during the depositional period of the second member of Triassic Jianglingjiang Formation (T1 j2). The intra-platform depression controlled the distribution of shoal around it during the early and middle period of T1 j2，and a large area of gypsum lagoons developed in the intra-platform depression during the late period. (3) The Linshui-Fengdu intra-platform depression，with around micro-paleo-geomorphology， controlled the distribution of grain shoals during the early depositional period，and high-quality dolomite reservoirs were more likely to be formed in the high parts of the peripheral structure. The continuous arid and evaporative environment formed a regional cap layer. (4) In general，the T1 j2 has good reservoir-forming geological conditions and is expected to be a strategic exploration area for searching as shoal-facies monoblock gas reservoirs. It is recommended that the high-energy intra-platform shoal facies development belt around the Linshui-Fengdu intraplatform depression should be the key exploration area of Jialingjiang Formation in eastern Sichuan Basin in the future.

Key words: tectono-sedimentary differentiation, lagoon, dolomite reservoirs, intra-platform shoal, Jialingjiang Formation, Triassic, Linshui-Fengdu intra-platform depression, eastern Sichuan Basin
