There are many important oil-gas resources in Feixianguan Formation of northeast Sichuan. Based on an analysis of rock core, field cross section, logging, well logging and thin-section observation data, the authors studied the sequence-lithofacies paleogeographic characteristics of Feixianguan Formation in south sector of Liangping-Kaijiang ocean trough. The result indicates that the sedimentary model of the study area belongs to the attached land platform which includes the platform, sloping ground, and residual ocean trough facies. With the system tract as the unit of the sequence-lithofacies paleogeographic map, this paper discusses in detail the lithofacies paleogeographic characteristics and evolution of various sequence system tracts.
