摘　　要：本文以LMD地区三维三分量(3D3C)地震资料为研究对象,较为系统地总结了三维转换波地震资料成像处理技术,如坐标旋转、叠前去噪、静校正、叠前时间偏移等,并给出了纵波、转换波联合处理流程;同时指出了Z分量、R分量联合处理与R、T分量联合处理在流程上的差异。通过实际应用,提高了三维转换波地震资料的成像精度,为三维三分量地震资料解释提供了较好的基础资料。In this paper 3D3C (3 Dimensional and 3 Component) seismic data in LMD area is our study object,based on the data we systematically summarized imaging techniques for 3D seismic converted data,such as coordinate rotation,pre-stack noise elimination,static correction,pre-stack time migration and so on,the joint processing flowchart for P wave and PS wave (converted wave) were presented,the difference between Z-component & R-component joint processing flowchart and R-component & T-component joint processing flowchart was pointed out.By application of the technique to field data,it can be seen that the imaging precision for 3D seismic converted data was greatly improved,as a result the high quality basic datasets were provided for further 3D3C seismic data interpretation.
