【摘要】 视反射率估计是地震数据处理解释中的一项重要内容,通常采用反演的方法得到.本文以地震偏移和地震线性反演理论相结合为基础,并利用保幅单程波传播算子和保幅波动方程叠前偏移算法以及成像空间中的角度域波动方程偏移成像和照明补偿等方法技术,提出了一种利用单程波波动方程偏移进行地下反射面视反射率估计方法,并进行了理论模型的数值试验.这种估计方法得到的视反射率估计是一种近法向入射的小角度反射率.更多还原

【Abstract】 The apparent reflectivity estimation is a fundamental issue in seismic data processing,usually it is obtained by the inversion approach.In this paper,based on the combination of seismic migration and seismic linear inverse theory,and using the preserved amplitude one-way wave propagator,the preserved amplitude wave equation prestack migration algorithm,and the techniques of angle-domain wave equation migration and illumination compensation in imaging space,an apparent reflectivity estimation method for subsurface reflector is presented through the one-way wave equation migration.Some numerical tests on theoretical model are implemented.The apparent reflectivity estimation obtained by the method presented in this paper is the reflectivity of small incident angle close to the normal direction.更多还原
