     Stratigraphic division and comparison of the Yingmaili condensate gas reservoir is a basic and important issue for terrestrial formation reser- voir geology and development engineering, and is also a key technical problem to be resolved. This paper follows the principle of ＂Start from standard co- ring wells, use cores to demarcate well logging, find auxiliary marker beds to do cycle comparison, control level by level, make division and comparison of interbeds in the identical cycle of sedimentation, determine sublayers by interbeds, and compromise the near and c~ose ＂. We redetermine the gas bear- ing formations, sand bodies and sub-layers which are suitable for gas field development. And we identify the unconformities between the Cretaceous and the Paleogene, the top boundary of the bottom sandstone in the Kumugeliemu Group and interbeds used to be supplementary means of stratigraphic division and comparison. This resolves well the problem of stragigraphic division and correlation of the Bashijiqike Formation-Kumugeliemu Group, which provides guidance for the late development of the Yingmaili condensate gas reservoir.
