Abstract：Lithostratigraphic reservoir is the most potential field of reserve increase.In recent years,the proportion of reserve of lithostratigraphic reservoir in discovered oil/gas reserve in China as a whole has been over 50%.The acquisition and processing of high-resolution seismic data,sequence stratigraphy,reservoir description and 3-D visualization have become main identifying techniques of lithostratigraphic traps.Through the study works of multiple objects in new oil/gas fields,the paper summarized a set of associated techniques identifying lithostratigraphic traps in different areas and implementation steps.The key of the works is to find out accurately the flood plane and sequential boarder,because the max flood plane and sequential boarder are main factors controlling developing level of lithostratigraphic traps.
