摘要
In Yuanba area of the northeastern Sichuan Basin, the reef-bank is characterized by deep burial depth and great lateral variation, hence is method. Based on well-seismic calibration and spectral decomposition of sh form, the frequency range of different facies is figured reef complex changing with frequency are described scientific guiding for petroleum exploration. in the Permian Changxing Formation difficult to predict by conventional ort windowed discrete Fourier trans- out. The form and plane distribution of platform margin The boundary of lithologic reservoir is confirmed, providing.
