摘要
In sand and shale interbedding strata, seismic reflection shows good stratification. So the relative high tuning energy in frequency spectrum imaging is often used to identify reservoir distribution. But for reef, volcanic vents and other special geological bodies, seismic reflection is complex. In terms of reverse thinking, the distribution of low tuning energy in spectrum imaging can reveal special geological bodies. The technology is now available and deployable. The results have been achieved by using the method for predicting reef and igneous reservoirs, which provides a framework and methodology for discovering special geological bodies.
