High-resolution coherency analysis technique and its application
高分辨率相干体分析技术及其应用

Many researchers use coherency analysis technique for studying geologic structures, faults and predicting fracture areas, but traditional methods have some limits. The basic principles of an advanced coherency analysis technique based on eigenvalue and electing methods of key parameters are studied . Many important parameters of reservoirs, such as faults, micro-fractures, lithology and lithologic facies etc., can be gained and the geologic production situation and microscopic changes can be more clearly described from high-resolution seismic coherence computation based on eigenvalue. So a powerful technical tool can be provided for geologists to research the structural deformation and variation of lithology. The practical processing of seismic data in the Chepaizi region in the Junggar Basin shows that good application result is achieved for the application of the high-resolution coherency analysis method to detect faults and fractures.
