【摘要】 经过油储地球物理和油气勘探二次创业前后18年的研究,基于保结构方法和拟微分算子技术,提出了算子运算转化为函数化运算、乘法运算转化为代数加法运算的波场有效表示方法,促进了快速有效的地震波场计算和资料处理方法的产出。高精度速度-深度建模、非对称走时时间偏移、叠前谱分解预测多次波、弹性参数反演、反假频重建等方法技术,正在实际资料试验研究中不断完善。更多还原

【Abstract】 The eighteen years of research on oil reservoir geophysics during the second round of hydrocarbon ex- ploration provided a sound basis for the proposition of an effective expression of wave field based on structure preserved algorithm and pseudo-differential operator technique.The expression transfers operator calculation into function calculation and multiplication into summation and promotes the development of rapid and effective methods of seismic wave field calculation and data processing.Various techniques such as high-precision depth- velocity estimation,asymmetric travel-time migration ,multiple prediction through pre-stack spectrum decomposi- tion,elastic inversion,and dealias reconstruction,are continuously sharpening in the process of practical applica- tions with real data.更多还原
