地震波时深转换方法初探

为建立地质分层与地震反射层的对应关系,时深转换是地震资料解释中提高勘探精度非常关键的一步。介绍了时深转换的原理、地震波速度的影响因素以及时深转换速度的求取思路,阐述了不同地质和地震地质情况下,不同的时深转换方法,结合层位、断层等的T0值,绘制出需求的构造图,以达到最佳的勘探效果。

Analysis on the Methods for Time-depth Conversion of Seismic Wave

In order to establish the correspondence between geological layer and seismic reflection layer,the timedepth conversion is a very crucial step for improving the exploration accuracy in the seismic data interpretation.This paper introduces the principle of time-depth conversion,the influencing factors of seismic wave velocity and the idea of seeking the velocity of time-depth conversion,and expounds different time-depth conversion methods under different geological and seismic geological conditions,and connecting with T0 values of horizons and faults,draws the wanted structural map in order to get the best results of exploration.
