Combining with regional seismic profiles, the paper makes thorough study on single well and interwells, then carries on detailed research to the plane distribution and vertical evolution characteristics of lithofacies palaeogeography characteristics of Middle Permian Shihezi Formation in southern ce prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" />ce w:st="on">ceName w:st="on">NorthceName> ceName w:st="on">ChinaceName> ceType w:st="on">BasinceType>ce>. Finally, a research about lithofacies palaeogeography and reservoir, cap rock characteristics of Shihezi Formation in southern ce w:st="on">ceName w:st="on">NorthceName> ceName w:st="on">ChinaceName> ceType w:st="on">BasinceType>ce> was operated on the basis of research result stated above and synthetical analysis data. The results provide a reliable geological data for the distribution regularity of favorable reservoir and oil-gas prediction of southern ce w:st="on">ceName w:st="on">NorthceName> ceName w:st="on">ChinaceName> ceType w:st="on">BasinceType>ce>.
