弹性波克希霍夫积分偏移法

P、S波同时偏移法是为了适应复杂构造地区勘探情况而开始研究的一种偏移方法。在前人工作的基础上,应用弹性波克希霍夫积分偏移的基本原理,改进了纵波（PP）及转换波（PS）的同时克希霍夫积分偏移方法,给出了一种近于实用的计算机流程和程序;并用其分别对射线理论合成反射波资料、有限元模拟地震波传播资料进行了检验,证明此种方法是有效的。在解决复杂构造地区的地震波成象方面,该方法具有很大的潜力。

THE KIRCHHOFF ELASTIC WAVE MIGRATION METHOD

The P and S waves simultaneous migration method is being studied to adapt to the prospecting situation of complex structure region. It makes extensive use of the signals of P and S waves in seismic data, so that a better result may be obtained than the normal migration method using P wave signal only This paper has improved the ordinary Kirchhoff integral migration method of using (PP) and (PS) waves simultaneously. The practical process and program of this method were completed. It was tested by using the synthetic seismograms obtained with reflection ray theory and finite element method, and some satisfactory results have been obtained, which prove the efficiency and potentiality of this method in solving the problem of migration in complex structure region.
