The tectonic activity and exploration potential analysis of subduction-accretionary belt at plate convergent margins are always difficult problems in oil geologic field.Myanmar is a favorite place for the study,which lies in the conjunction area of the Eurasian Plate and Indian Plate.The tectonic evolution,structural domain division and petroleum exploration prospects are studied based on the carefully study on the wells,outcrops,seismic data and regional background information.It can be divided into three structural domains:Accretionary wedge,slope basin and trench.The hydrocarbon accumulation condition is favorable in Bengal fan trench region,and hunting for turbidite sand bodies and subtle reservoirs is the key to petroleum exploration.
Key words： Subduction-accretionary belt; Accretionary wedge; Slope basin; Trench; Myanmar.
