摘要

To further improve interwell prediction accuracy of single channel of fluvial facies, a fine prediction method of thin sand body in single channel of fluvial facies using combined well-seismic data is proposed in this paper. According to attribute response and spectrum analysis of seismic data, the energy body with discrete frequency is extracted with frequency division processing technique based on wavelet transform, which can reflect thickness grade of single sand body. After calculation of channel edge detection attribute, the pre-analysis of spatial patterns of single-layer is conducted with horizontally slicing technique, and the prediction of single channel is finally completed based on well calibration.
