摘要
合肥盆地是与大别山造山带有密切关系的山前前陆盆地,盆地中、新生界沉积物主要来自南面大别山区以及盆地东部、北部剥蚀区。通过野外实际踏勘、室内岩石薄片显微分析,认为合肥盆地中、新生界发育的沉积相主要有冲积扇相、河流相和湖泊相,其中以河流相最为发育。该盆地中、新生界油气源条件比较丰富,储盖条件良好,生储盖组合形式多样,存在多种油气圈闭类型,是一个油气勘探潜力较大的陆相沉积盆地。
The Hefei Basin is a foreland basin, that was constrained by the successive northward overthrusting of the QinlingDabie orogenic zone in the south and strikeslip faulting of the TanchengLuxian fault in the east during its development. The Mesozoic and Cenozoic sediments are derived from the Dabie mountain area in the south and denudational areas in the eastern and northern parts of the basin. The sedimentary facies in the basin consist significantly of alluvial fan, fluvial and lacustrine facies. The basin is characterized by abundant source rocks, good reservoirseal conditions, various sourcereservoirseal associations and oil traps, indicating a great petroleum potential in the basin.
