Abstract: In order to study sedimentary facies partition of sparse well area, and analyze the sedimentary environment, frequency division interpretation technology is used for processing analysis, the purpose is to solve the above problems. Frequency division interpretation technique converts seismic data from time domain into the frequency domain using the discrete Fourier transform method in order to observe sandstone transverse discontinuity, which plays a role of lateral prediction. Based on the principle of frequency division interpretation technique, it depicts the channel sand body in the HST of the second section of Damoguaihe late formation in Sue Nenol. Comparing with conventional seismic attributes, frequency division has a good response to identify channel sand body boundary, plane distribution morphology, and lateral discontinuity. It is a better guide for the classification of sedimentary facies on sparse well area. Finally, the conclusion is that the HST of the second section of Damoguaihe late formation in Sue Nenol mainly developed in Anastomosing River Delta. In sparse well area, it developed the features of distributary channels, characteristic is very clear and it overcomes the problem of non-well constraint.
