摘要
Considering lacking coring and well data, high-resolution 3D seismic data from the study area was analyzed to study the architecture and evolution of sedimentary elements on the upper Bengal fan. The area belonged to deep-water region, and stratigraphy was formed in marine deposition. Six typical seismic facies were identified, which were incised channel fill facies, gull wing-shaped facies, wedge-shaped divergent facies, transparent facies, high-amplitude parallel facies and low-amplitude parallel facies. Through analysis of S-N and E-W seismic profiles reflection charateristics,seismic attribute planeform, the authors revealed the sedimentary evolution.
