摘　　要：研究区位于缅甸西部沿海若开海岸平原,是孟加拉盆地东侧吉大港山前坳陷褶皱带的延伸部分,通过钻井、露头和地震的综合研究,确定该区为经典增生楔地层模式,增生楔构造地层裹卷了古洋壳、海沟、陆壳碎片及古岛弧沉积,并且由于挤压推覆多次,构造变形强烈,地层叠置混杂。文章基于研究区的沉积构造特征和石油地质背景,综合利用地质、地震、钻井、测录井、岩心化验以及地球化学等资料,从区域构造及沉积演化、区域地层、烃源分析、储层研究等多方面,对其石油地质特征进行分析,明确油气的有利聚集带,探讨其勘探的潜力。The block of Myanmar, the extension part of Chittagong piedmont depression fold belt in eastern Bengal Basin, is located in Arakan coastal plain in the westem part of Myanmar. With comprehensive research on drilling, outcrop and seismic, the region of interest is confirmed as a typical model of accretionary wedge stratum. Paleo-oceanic crust, trench, continental crust fragments and ancient island arc deposition are wrapped in this accretionary wedge stratum, strong tectonic deformation and mixed overlapped strata occurred because of repeatedly extrusion and thrusting nappe. Based on sedimentary and tectonic characteristics and petroleum geological background, and in combination with geology, seismic, drilling, logging, core test and geochemical data. etc, the petroleum geological characteristics can be studied through regional tectonic, sedimentary evolution, regional stratigraphy, hydrocarbon source analysis, reservoir research, etc. In accordance with these data, we could know the favorable oil and gas accumulation zone and then evaluate its exploration potential.
