Abstract: Based on the sedimentary facies map with well data, the prediction accuracy can not accurately describe the exact location of the sand bodies. Inoue information has a high vertical resolution, seismic information can reflect the distribution of geological information in the plane, with a certain horizontal resolution, well seismic combination of sedimentary facies fine description of the sand body distribution and river distribution patterns, and combined with well data to verify the relationship between the wells sand body, so as to obtain more accurate geological information, more effective to achieve the plane sedimentary facies characterization, to provide the basis for further production and development.
