地下地质条件比较复杂时，地震反射波成像效果不理想，致使常规反射地震勘探难以奏效。本文基于点散射地震－地质模型，推导出2D散射波时距曲线方程，分析了地震散射波的运动学规律；在此基础上，提出了2D地震散射波成像的方法与技术；结合断层模型和一套实际地震资料处理，讨论了散射波地震成像的特点，并与传统反射波成像结果进行了比较，证明了该方法的有效性。

Seismic reflection imaging result is not satisfactory when the underground geological conditions are much complex,and the conventional reflection seismic exploration would be ineffective.In the paper,one 2D seismic scattering wave imaging method is achieved from the time-distance curve equation of 2D scattering wave based on the seismic-earth model of point scattering,and the seismic scattering wave kinematics law is ana-lyzed.With the processing results of fault model and a set of real seismic data,the characteristics of the seismic scattering wave imaging technique is discussed,and the imaging results of traditional reflection imaging tech-nique are compared to prove the effectiveness of this method.
