本文综合应用了波动方程旅时反演和波形反演法,根据井间地震数据重建了井中速度分布图。该反演法称之为WTW,它保留了全波反演和旅时反演的优点。例如,它的特性可通过适当的快速收敛确定,且与起始模型无关;它可以分辨速度模型的细节。该方 In this paper, the wave equation inversion and waveform inversion are applied in a comprehensive way, and the well velocity profile is reconstructed from the crosswell seismic data. The inversion method is called WTW, which retains the advantages of full-wave inversion and travel-time inversion. For example, its properties can be determined by appropriate fast convergence, independent of the starting model; it can distinguish the details of the speed model. The party
