摘　　要：珠江口盆地自20世纪80年代初开展大规模油气勘探以来,在北部裂陷带及中央隆起区已陆续发现了20多个油气田。目前北部裂陷带及中央隆起区勘探程度较高,盆地南部裂陷带及隆起区处于深水区域,勘探及研究程度甚低。近几年油气勘探获得了重大突破和进展,展示出巨大的勘探前景。在前人研究的基础上,根据盆地不同区域油气运聚成藏条件及特点,分区带对其油气资源前景及有利勘探方向进行剖析,明确提出,北部裂陷带中深层领域和南部裂陷带白云凹陷及周缘深水区是油气勘探的新领域和有利方向,应进一步深化研究、加快油气勘探步伐。Since 1980, more than 20 oil-gas fields have been found in northern rift zone and central uplift zone of Zhujiangkou basin, with the annual production above ten million cubic meters. Up to now, the exploration extents in these zones are higher, but the middle-deep prospecting effort is fewer. However, the rift and uplift zones in southern Zhujiangkou basin situated in deep water region with much lower extent of oil-gas exploration and research have obtained significant breakthrough and progress in recent years, showing huge petroleum resource potentials or prospects. Based on previous studies on the oil-gas migration and accumulation as well as reservoir conditions and characteristics in this basin, it is suggested that the middle-deep layer in northern rift zone and the Baiyun sag and surrounding deep water zone in southern rift zone are favorable zones or targets for further exploration, and in-depth research and adding efforts for petroleum exploration should be required here.
