Under a fixed seismic frequency，wavelet side lobes may increase the difficulty of interpreting and recognizing thin sand bodies. To investigate the impacts of wavelet side lobe effects，we design a series of forward models and produce synthetic seismic profiles using zero phase Ricker wavelets of different frequencies. The purpose is to identify the relationship of sand body location and frequency with side lobe effects. This study also aims at exploring the relationship between amplitude attributes and the description of thin sand bodies. The results show that，an integrated use of multiˉfrequency profile and amplitude attributes can reliably interpret and describe thin sand bodies of braided river facies which are thicker than1/8wavelength.
