英文摘要Quantitative analysis of geological complexity in terms of seismic imaging is an important way to measure the coherent interaction of geological heterogeneity spectra with the migrator used. Based on previous studies, we introduce several new strategies to evaluate the complexity of subsurface heterogeneous media, the main features of which are use of a velocity co-occurrence matrix for velocity variations and use of the Hough transform for dip-angle calculations. First, the velocity co-occurrence matrix is created by statistically classifying adjacent-point velocity contrasts, after which the scaling characteristics of migrators are directly incorporated into the matrix for presenting seismic imaging complexity. Second, vertical velocity variations are also taken into account using a depth-velocity co-occurrence matrix. Third, we apply the high-precision Hough transform to locate geological interfaces and estimate the dip angle of each point before calculating angular complexity. Finally, considering the indivisibility of the effect of both lateral/vertical velocity variations and dip angles, we define a comprehensive coefficient to assess the seismic imaging complexity of complex geological structures. Tests on the 2D SEG slat model and field data demonstrate that the new strategies proposed for evaluating geological complexity are reliable and applicable to different degrees of geological complexity due to the sensitivity of the method for detecting small and large velocity contrasts as well as dip-angle variations.
