SEISMIC SECTION PROCESSING BY DYNAMIC COMPRESSION METHOD. Pt.2
Ambiguity at interpretation of seismic sections is mostly caused by reflection interference and record-frequency characteristics. These factors limit temporal resolution of a section and, therefore, detail of structural imaging of complex geological features. An increase in temporal resolution by means of a frequency filtration is not often the optimum decision. The dynamic compression – the method of seismic section processing realizing a record inverse filtering in the time domain is considered. As a result of such inverse filtering, a wave section is transformed to the field of delta functions which reflects the structure of seismic boundaries and can form a basis for development of a litho- physical model of the environment. The first part of the paper described processing algorithms and model results. This part considers results of the method testing on real geological features using drilling data.
Key words: seismic sections, dynamic compression, inverse filtering, interference, wavetrains, wavelets.
