摘要
近年的研究表明,潮汕坳陷是珠江口盆地的一个大型残留坳陷,其内沉积了上三叠统-下侏罗统、下白垩统和上白垩统等3套海相地层.潮汕坳陷含油气系统有别于珠江口盆地其它凹陷,其烃源岩、储层和盖层均为中生代地层,并具有大型构造圈闭,且构造与油气运聚关系匹配良好,将成为珠江口盆地最有希望的后备油气勘探区.
Recent researches indicate that Chaoshan depression is a big residual depression where three sets of Mesozoic marine sequence deposited,i.e.Upper Triassic Lower Jurassic,Lower Cretaceous and Upper Cretaceous.Its petroleum system is distinct from those of Zhu I and Zhu Ⅱ depressions in Pearl River Mouth Basin,because its source rocks,reservoirs and seals are all Mesozoic.In addition,there are many large scale structural traps which match hydrocarbon generation,migration and accumulation very well in Chaoshan depression. Therefore the depression should be the most hopeful area of future petroleum exploration in Pearl River Mouth Basin.
