AI Technical Summary
Existing technologies for predicting carbonate reservoirs in complex lithological backgrounds suffer from problems such as complex lithological backgrounds, difficulty in distinguishing reservoir response characteristics, and weak integration with geological backgrounds, resulting in imprecise predictions.
Using a geological-geophysical approach, we collected various data to establish an isochronous stratigraphic framework and seismic-sedimentary facies calibration. By combining forward modeling and geostatistical inversion, we eliminated the influence of interfering lithology and conducted reservoir response analysis and prediction.
It improves the accuracy of planar prediction of carbonate reservoirs, reduces the ambiguity of seismic prediction, and provides more refined guidance for reservoir distribution and production well location deployment.
