摘要
本文结合传统3D抛物Radon变换(PRT)和AVO数据正交多项式拟合,给出了3D高阶抛物Radon变换方法(HOPRT).该变换增加了描述AVO数据变化的梯度信息和曲率信息,拓展了传统3D抛物Radon变换方法,使其在具有AVO特征的数据重建中具有更高的准确度,从而提高AVO分析的可靠性.文中给出了3D高阶抛物Radon变换进行地震数据保幅重建的流程.理论模型和实际地震资料的重建结果显示了本文方法的优点.
3D high-order parabolic Radon transform（HOPRT）method for amplitude preserving reconstruction is proposed on the basis of the traditional 3D parabolic Radon transform and orthogonal polynomial fitting techniques.The information on the amplitude and its gradient and curvature of the AVO data are taken into account in the 3D parabolic Radon transform,which makes the proposed method have higher accuracy for AVO data.We present a workflow for seismic data reconstruction with amplitude preserved by the method of HOPRT.The results of the synthetic model and the field data demonstrate the effectiveness of the method.
