摘要:

断陷盆地中常见横向凸起、走向斜坡两种典型传递带类型,与之对应的断层下降盘普遍发育大型扇三角洲或浊积扇砂体,其控砂作用的机制在于同沉积断裂活动导致的古地貌差异,尤其是传递带断层下盘的古地貌低地对物源供给水系起着汇聚和引导作用.此外,在盆地中央的大型纵向隆起带上发育的反向平行型传递带,其形成的断沟、断槽常常成为沉积物轴向输送的通道.

Abstract:

Two typical transfer zones,the lateral uplift and the strike slope,are common in rifted-basins.Large-scale sandbodies of fan delta or turbidite fan are generally developed in the corresponding down throw blocks.The controlling mechanism of these transfer zones on sandbodies is the differential palaeotopography caused by syndepositional faulting,especially the convergence and guidance of drainage systems by the palaeotopographic low on the down throw blocks in the transfer zone.Apart from that,the antithetic parallel transfer zone,developed at the large lengthways uplift belt in the central of rifted-basins,usually forms fault-troughs serving as axial channels for sediment transportation.

Key words: transfer zone, extensional structure system, reservoir prediction, rifted basin
