Non-structural trap interpretation of guanzhen sub-depression, hongze depression

摘要

Based on the principle of sequence stratigraphy, the time-space domain distribution of source, reservoir and seal rock developed in Hongze depression is predicated. Using various interpretation methods including acoustic impedance inversion, genetic interpretation, model interpretation and seismic attribute extraction, etc. , three potential prospecting belts and lots of non-structural traps and compound traps of structure and lithology are discovered in 3-D seismic survey in Guanzhen sub-depression of Hongze depression through non-structure interpretation.
