Control of relatively low paleogeomorphology on sandbodies (Taking PSS5 of BZ26 area as an example). a is the seismic reflection characteristics of distributary channel sandbodies in cross section (Section location is shown is Fig. 14d); b shows the seismic reflection characteristics of distributary channel sandbodies in vertical distribution (Section location is shown in Fig. 14d); c is a 3-D display of PSS5 palaeogeomorphology. Obviously river channel marked in the figure provided good geomorphologic background for the distributary channel sandbodies of Fig. 14d; d is the stratal slicing of root mean square amplitude of PSS5
