The formation mechanism and recognizing method of high resolution strata architecture boundary of single sand bed in fluvial strata were analyzed.The results show that the fluvial channel incises former sediments and gets accommodation first,and then the accommodation is filled,and after the flood mud is deposited,a single bed is formed.On the basis of the analysis,5 types of superimposed style and correlation modes of channel sand body are summarized,and it is considered that the superimposed style of channel sand body is controlled by A/S.On the basis of the analysis of reforming and effects of auto cycle on different cycles in fluvial strata.The recognizing mark of high resolution strata architecture boundary of single sand body scale and the correlation method in fluvial strata were summarized,in which auto cycle was correlated under the control of different cycles.
