Tarim basin Kuqa depression piedmont complex structural interpretation technology

Tarim Basin Kuqa piedmont has the characteristics of complex seismic geological conditions and difficult structural interpretation, using drilling, logging, geological outcrop, remote sensing information, signing layer's characteristic wave group comparison and other means comprehensive calibrate seismic geology horizon, layer's occurrence, fault location and structural style; fully identify stratigraphic unconformity surface, growth strata, detachment fault, and other geological phenomena, judge structural deformation characteristics and evolution; Use seismic and non-seismic data, extensively carry out forward modeling and forward model's processing interpretation, joint with seismic data's processing, analyze complex seismic wavefield characteristics to identify effective wave group; analyze salt structure deformation characteristics, build plastic deformation model; using 3D ray tracing or layer velocity filling method building velocity model, and applied to pre-stack depth migration data processing. Through comprehensive interpretation technology means improve the precision of structural implementation.
