| 摘 要： | 在较详细分析南沙海域区域地质背景的基础上,研究该海域主要沉积盆地地质构造特征,分析不同区域沉积盆地的油气地质条件,研究和总结各盆地中的油气分布特征。研究表明,万安盆地、曾母盆地和文莱-沙巴盆地具有丰富的油气资源,北康盆地、北巴拉望盆地油气资源远景次之,礼乐盆地和南薇西盆地油气资源远景较差。

| Abstract: | Lying in the southern part of South China Sea, the Nansha sea area includes the Nansha massif and Liyue-Northeast Palawan massif, and nine basins, namely, Zhongjiannan basin, Wan′an basin, Zengmu basin, Beikang basin, West Nanwei basin, Liyue basin, Brunei-Sabah basin, North Palawan and West Palawan basins. These basins are characterized by huge thickness of sedimentary rocks, which show excellent petroleum geological conditions with multiple sets of source rocks in different geological periods, multiple sets of reservoir rocks in Oligocene-Miocene and multiple sets of cap rocks of Pliocene-Pleistocene. About 19 oil-gas fields have been disco- vered in Wan′an Basin, 43 gas fields, 23 oil fields, 13 gas-bearing structures and 7 oil-bearing structures were verified in Zengmu Basin, 41 oil-gas fields and 8 gas fields were found in Brunei-Sabah Basin, and 16 gas fields were confirmed in North Palawan basin. However, no oil or gas fields were found in basins other than the nine as mentioned above. Our study on petroleum geology and oil-gas field distribution shows that the richest petroleum potential was shown in Wan′an Basin, Zengmu Basin and Borneo-Sabah Basin, and richer petroleum potential was demonstrated in Beikang Basin and northern Palawan Basin, but only some petroleum potential was verified in Liyue Basin and West Nanwei Basin. |
