In detailed study on sedimentary characteristics of Fu Yang reservoir around Threezhao area, based on the theory of high resolution sequence stratigraphy of the base level cycle isochronous contrast, regard short-term base-level cycle as the minimum isochronous contrast comparing unit, this paper has carried on the fine high-resolution isochronous contrast of the reservoir in the studied area, and the high resolution[1] sequence division of different orders of base-level cycle of Fuyu oil layer and Yangdachengzi oil layer. The Fuyu reservoir is divided into one complete long-term base-level cycle and three complete medium-term base-level cycle; while Yangdachengzi reservoir is divided into a long-term base-level rise hemicycles and 3 middle-term base-level rise hemicycles. According to mud logging, well logging and core analysis data, the sands group stratified mark of the Fuyu reservoir has been determined.
