Abstract:Presented here are differential-based gradient method and Laplace transform method which are used for laminating processing of seismic image.The laminating processing of seismic image can highlight the kinematieal characteristics of seismic wave and favour lamination tracing.The processings of model diffraction record and of ultrasonic record taken from a complex geological model show that gradient method and Laplace transform method favour highlighting reflection boundary and improving image clarity,but low-pass filtering is not suitable to complex image.
