摘要
依据珠三坳陷油气的物理化学性质和组成特征（碳同位素组成，轻烃特征及生物标志化合物的分布），排烃温度，烃源岩的地化特征与储层石英胶结物内与含烃包裹体共生的盐水包裹体的均－温度资料，进行珠三坳陷的油气源与油气藏充填史综合研究取得了新认识：文昌9－1，9－2构造的轻质油和天然气为腐泥型有机质（1／Ⅱ，型干酪根）与腐殖型Ⅲ型干酪根混合来源；文昌13－1，13－2构造与文昌8－3构造的油气主要来自文昌A 凹陷；文昌13－1，13－2构造中的油气来自同一烃源岩，珠三坳陷曾经经历了两期油气充填。
Multiple analyses include carbon isotopic,light weigh hydrocarbons GC-MS,and petrography and temperature of fluid inclusions are used for oil-source correlation and filling history research in Zhu Ⅲ depression. The light oils(condensates)and gas in Wenchang 9,8 and 13 areas originated from the source mainly composed of type Ⅰ/Ⅱ1 and mixed with some type Ⅲkerogen. The oil/gas in those areas mainly derived from Wenchang A sag. The two episodes of hydrocarbon filling had took place in the study area.
