| 英文摘要 | Trying to use the dynamic method and aiming at enhancing the analysis and assessment of seismic survey, we present a one-way wave equation based angle domain illumination analysis method. This method can be used to design seismic survey and has significances to pre-stack images evaluation, pre-stack amplitude compensation and AVA inversion. The angle-varied seismic incident intensities of the horizontal and slant layers at the subsurface targets are gotten through analyzing of the wave field forward/backward propagated from a point-scatter located at the subsurface targets. Since the one-way wave equation methods can be used to model the wave propagation in complex velocity models well, and get the wave-fields with quite correct amplitudes and multiple arrivals, they are used during the forward/backward propagating to make use of the correct amplitudes and multiple arrivals concisely. The method in this article can illuminate the subsurface targets under complex overburden. Moreover, the geometric divergence of illumination energy is compensated to highlight the evenness and extension of illumination in angle domain, which makes the analysis results can be used directly to the AVA analysis and compensation. A fast one-way wave equation modeling scheme, frequency and velocity dependent varying-step depth exploration theme, is introduced according to the characters of the illumination analysis. Numerical tests show the effectiveness and feasibility of the illumination method in this article. |
