摘要
通过采用目前国内最先进的测试手段对单个有机包裹体的成分，分子结构及其中烃类的成熟度进行了分析，结合其它地质，地球化学资料综合研究认为，琼海凸起系由文昌A、B两凹陷双重供油，其中文昌A凹陷是琼海凸起的主要油源区，有机包裹体均一温度测定结果表明：文昌A凹陷有过两期油气运移，第一期有机包裹体的均一温度为120－140℃，第二期有机包裹体的均一温度为150－170℃，两期有机包裹体在成分，烃类成熟度以及分布特征上都存在明显差异，文昌B凹陷经历了一期油气运移，有机包裹体的均一温度为1200－140摄氏度，有机包裹体特征与方昌A凹陷两期有机包裹体的特征均有所不相同。
Using several updated tools,this paper has analysed composition,structure and maturity of monoinclusions in ZhuⅢ Depression. In combination with other geological and geochemical data,it can be concluded that Qionghai uplift may derive oil from Wenchang A and B sag,with the former being the main source area. The homogenization temperature data of oganic inclusions suggests that there are two stages of hydrocarbon migration in Wenchang A sag,with the homogenization temperature ranging 120-140℃ and 150-170℃ respectively. The two stages are also obviously different in composition,maturity and distribution of organic inclusions. For Wenchang B sag,there is only one stage of hydrocarbon migration,with the homogenization temperature ranging 120-140℃,and its organic inclusions are also different from those in Wenchang A sag.
