AI Technical Summary
Existing technologies struggle to accurately predict the planar distribution of marine hydrocarbon source rocks, especially when seismic data quality is poor. Directly using seismic data for prediction presents multiple solutions.
By obtaining marine source rock cores, constructing a well logging identification scale, and combining seismic inversion constrained by natural gamma curves, the thickness of the source rock is determined by seismic stratigraphic calibration, thereby predicting its planar distribution.
It improves the accuracy of predicting the planar distribution of marine source rocks, solves the problem of multiple solutions in seismic data, and achieves accurate prediction of the thickness and distribution characteristics of source rocks.
