Abstract: Since 1980, more than 20oil-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.

Key words: Zhujiangkou basin, middle-deep layer, petroleum resource potential, new exploration domain
