Abstract:

The inner architecture and sequence configuration of the Paleogene in Baxian Sag are analyzed. Niudong fault and the related E-W zonation and S-N segmentation divide Baxian Sag into three structure-geomorphic units ( the south, north and middle segment) . The sequence configuration, development degree of provenance system, the depositional system and the genetic type of sand bodies, and the allocation type between the sand bodies and the structure-geomorphy of each segment are apparently different.

Key words: Sangonghe Formation, petrology characteristics, characteristics of porosity and permeability, pore structure, diagenesis, Shawodi area
