文摘
- •
Paleogeomorphologic elements on Cretaceous unconformity were reconstructed.
- •
Seismic lithology of 1–7 m thick sandstones was realized using 90° seismic traces.
- •
Amplitude stratal slices illustrate lobate sedimentary geomorphologic patterns and sandstone thickness trends.
- •
The agreement between above elements reduces uncertainties of mapping ultrathin sandstone reservoirs.
