Abstract: Based on the synthetic analysis and evaluation of remote sensing data in petroleum geology in southeastern margin of Tarim basin, it is suggested that the study area has undergone three evolutional stages- Paleozoic platform, Mesozoic foreland basin and Cenozoic depressional basin. There are well-developed source-reservoir-cap assemblage and favourable oil-gas migration and accumulation condition. Five circular structures interpreted from Landsat MSS images are favourable prospecting play.
