摘要
Abstract
Generally,strike-slip fault formed under pressure torsion stress field has the characteristics of steep section,flower structure,etc.Its structural feature is complex,and it is difficult to accomplish fault interpretation.The data quality of the same seismic profile at shallow,middle and deep segment has great difference.Therefore,the definition of breakpoints and fault section is also different.Based on the geological background,the Reliability of fault interpretation can be improved by u-sing seismic data with different dominant frequency at different interval.Three parameter wavelet transform is much better than Fourier transform and Morlet wavelet transform in time-frequency focusing.The best effect of fault imaging can be obtained by this method in different dominant frequency of seismic profiles,and it is also convenient for manual interpretation and credibility enhancement.There are large amount of strike-slip faults in Nanpu Sag.Three parameter wavelet frequency processing tech-nique has been applied to seismic data processing and fault interpretation and better effect has been achieved.关键词
