主　　题：Bengal fan Rakhine basin Architectural element Sedimentary evolution 

摘      要：Since the consecutive discovery of several gas fields from 2004 to present,the Rakhine Basin has been an active area for petroleum exploration in the Bay of ***-resolution 3D seismic data and well data from blocks AD1,AD6 and AD8 offshore northwest Myanmar are used to study the Miocene–Pleistocene depositional architecture and sedimentary evolution in the Rakhine *** of seismic facies and seismic attributes indicates that deep-water architectural elements include submarine canyons,confined slope channel complex systems,aggradational channel–levee complexes,isolated channels,frontal splays and mass-transport complexes,which have variable characters(shape,dimension,sedimentary architecture)within predominantly background deep-water slope-basin floor *** of the sediments are interpreted to be sourced from the Ganges–Brahmaputra fluvio-deltaic system to the north with only minor lateral input from the IndoMyanmar Ranges to the *** of the depositional evolution and architectural elements transformation during the filling history of the Rakhine Basin suggests the Rakhine Basin experienced rapid progradation during the Oligocene–Middle/Upper Miocene,gradual retrogradation during the Middle/Upper Miocene–Early Pliocene and gradual progradation during the Early Pliocene–*** exploration results indicate that the main reservoirs of the discoveries in blocks A1 and A3 are Pliocene frontal splays and channel–levee fills,dominated by fine and very fine-grained sandstones,in structural and structural–stratigraphic *** results from seismic characters and several exploration wells indicate that channel complexes and associated overbanks and frontal splays with fine-grained sandstones and siltstones trapped by the four-way closures are primary reservoir targets.
