Abstract: Reservoir type is relative to the tectonic and sedimentary evolution in the continental margin deepwater area of the northern South China Sea.The continental margin deepwater area of the northern South China Sea experienced three phases of sedimentary evolution including rifting phase,transitional phase from rifting to depression,and depression phase.Different types of reservoirs were developed in different sedimentary evolution phases.The reservoirs in the deepwater area mainly include the fluvial and fan delta sandstones in the Eocene to Lower Oligocene rifting phase,the(fan) delta and littoral-neritic sandstones in the Upper Oligocene transitional phase,and the littoral sandstones,platform carbonate rocks and deepwater turbidite sandstones in Miocene depression phase.The lowstand sandstones,including the slope fan,basin floor fan,progradational wedge and canyon channel,were distributed broadly in the continental margin deepwater area of the northern South China Sea.These sandstone bodies have the enormous exploration potential in deepwater area.

Key words: northern South China Sea, deepwater area, delta sandstone, platform carbonate rock, deepwater turbidite sandstone:lowstand sandstone, exploration potential

摘要: 南海北部大陆边缘盆地深水区储层类型与构造、沉积演化有密切的关系。南海北部陆缘盆地深水区经历了裂陷期、裂坳过渡期、坳陷期3个沉积演化阶段,不同沉积演化阶段发育不同类型的储层。深水区的储层主要包括:始新统—下渐新统裂陷期的河流和扇三角洲相砂岩;上渐新统裂坳过渡期的(扇)三角洲—滨浅海相砂岩;裂后坳陷期中新统的滨海相砂岩、台地碳酸盐岩及深水浊积砂岩。其中,南海北部陆缘深水区广泛分布的斜坡扇、盆底扇、进积楔形体和峡谷水道等低位砂体具有巨大的勘探潜力。
