【摘要】 汇聚板块边缘俯冲增生带的构造活动与油气勘探潜力研究一直都是石油地质界的难点,地处印度板块与欧亚板块交会处的缅甸若开海岸是开展这一研究的绝佳区域。通过对缅甸俯冲增生带的钻井、地质露头以及地震资料的认真分析,将研究区划分为增生楔主体、斜坡盆地和海沟3个构造单元,并在此基础上探讨了各构造单元的油气勘探前景,指出位于孟加拉湾东侧的海沟地区油气成藏条件最为优越,寻找深水浊积砂体应成为该区重点勘探方向之一。更多还原

【Abstract】 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.更多还原
