MULTI WAVE FIELD DECOMPOSITION BY THE VARIABLE VELOCITY METHOD IN F K DOMAIN
【摘要】 波场分离是多波多分量地震资料处理的基础工作,本文利用多波资料的动力学和运动学特征在F-K域实现多波炮集记录变速波场分离,可分解x-z分量中的P-P波和P-SV波,经过对理论模型和物理模型x-z二分量记录的试处理,获得了分解效果良好的P-P波和P-SV波记录
【Abstract】 The wave field decomposition is an important basic work of the multi wave multicomponent data processing. By using of the characteristics of dynamics and movement of the seismic wave, the decomposition of multi wave shot records is realized by the variable velocity method in F K domain. The P P wave and P SV wave in the x z two component records can be decomposed by the method. Having processed the x z two component records of both the theoretic and physical models, the good decomposed P P wave and P SV wave records were obtained.
