【Abstract】 Based on high-precision three-dimensional seismic, logging and drilling data in Guanghao Area, forward modeling of different lithological associations is carried out longitudinally to summarize the law of seismic response caused by lithological changes. Lithologic and lithofacies zones are divided horizontally by combining seismic facies and sedimentary facies and the sensitive attribute parameters are selected to characterize the plane distribution range of seismic anomalies. At the same time, on the basis of petrophysical parameter transformation, the pre-stack index factor inversion is carried out to quantitatively describe fluid properties, and good results are obtained.更多还原
