转换波人工合成地震记录制作及纵、横波层位对比

Making C-wave synthetic seismogram and correlation of P and S-waves events.

转换波人工合成地震记录的制作及其与纵波资料对比标定层位 ,是应用多分量地震资料进行解释的基础。采用全波列测井资料制作转换波人工合成地震记录 ,需要考虑地层倾角、岩层各向异性、横波测井资料的环境校正等多种因素的影响 ;在纵、横波资料对比中 ,又需要考虑极性、井资料的深时转换、子波带宽等的影响。本文从模型资料和莺歌海盆地实测多分量资料出发 ,研究了转换波人工合成地震记录具体制作的方法和步骤 ,以及纵、横波对比标定中的基本问题和解决方法。

Making C wave synthetic seismogram and correlation calibration of horizons together with P wave data are the basis using multi components seismic data for interpretation.When using full wave train logging data to make C wave synthetic seismogram,it needs to consider the influence of many kinds of factors such as dip and anisotropy of bed as well as environment correction of S wave logging data etc.In correlation of P wave with P SV wave data,it also needs to consider the influence of polarity,depth time conversion of drilling data and bandwidth of wavelet etc.Starting from model data and real multi components data of Yingge sea basin,the paper studied the method and concrete step of C wave synthetic seismogram as well as existed problems and solving method in cooperating P with P SV wave for correlation calibration.The correlation calibration of real data showed the correctness of the method.
