一种有效的转换波静校正方法

A Effective Method Of Converted Wave Statics

转换波技术由于具有常规P波勘探无法相比拟的优点而成为当前地震勘探中的一门新技术。而静校正在转换波勘探中是处理的重点和难点。为此很多学者专家为此提出了各自的解决办法,但是由于转换波静校正问题的复杂性,该问题至今仍尚未圆满解决。本文首先在转换波的CRP(共接收点)叠加剖面上追踪拾取同相轴,然后结合纵波对应层位的地下构造求取接收点的横波静校正量。该方法通过对理论模型和实际资料的试算验证了其有效性。

The new technology of converted wave has the advantages than normal P wave exploration. And the statis is the important one of the exploration of the converted wave. So many experts bring for- ward the solution of the question. Because the complication of the question, it still not yet completion ac- count for. This paper first pick up the lineups in the CRP stack profile of converted wave . And then com- bined P wave corresponding layer of underground tectonic strike a reception point of the S wave static cor- rection. The method tested by the theoretical model and the actual data to validate its effectiveness.
