南海油气资源综述及开发战略设想

OIL AND GAS RESOURCES IN THE SOUTH CHINA SEA AND ITS DEVELOPMENT STRATEGY:A REVIEW

南海是西北太平洋的边缘海之一,海底地形复杂,南、北宽而缓,东、西窄而陡,陆缘发育一系列沉积盆地。南海油气资源丰富,有"第二个波斯湾"之称。综合介绍了南海北部大陆架油气区,西沙、中沙远景区,深海区,礼乐-太平远景区和南海南部大陆架油气区的沉积盆地,并对这些沉积盆地的资源量和油气远景进行综述。按照对南海石油地质特征的认识,将海域分为油气生产区、远景区以及无远景区(深海区)三种类型。针对不同的区域,采取不同的开发战略设想。应该加速北部大陆架油气区这一海域油气资源的开发利用;西沙、中沙远景区经过地球物理勘探、区域研究,选准靶区,重点突破;在南沙海域,应遵循"主权属我,搁置争议,共同开发"的主张,调整战术,以我主动开发,代替对方单独开发,最好形成联合开发。

The South China Sea is one of the marginal seas in the northwest Pacific with complex submarine topography.Its north and south shelves are wide and gentle,and the west and east shelves are narrow and steep.There are a series of sedimentary basins on the continental margin.They are rich in oil and gas resources and could be compared with the Persian Gulf as resource potential is considered.We made a brief review in this paper of the sedimentary basins in the oil and gas zones on the north continental shelf of the South China Sea,the potential zones in the Xisha Islands,Zhongsha Islands and abyssal region,the Lile-Taiping potential zone and the oil and gas zones on the south continental shelf of the South China Sea.Estimated resource and hydrocarbon potentials of these sedimentary basins are presented.According to the understanding of petroleum geology of the South China Sea,we divided the study areas into three types： the oil and gas production area,the prospective area and the area without prospect（abyssal region）.Development strategies should be built for different areas.Exploitation and utilization of resources should be accelerated in the oil and gas zones on the north continental shelf of the South China Sea.In the areas of the Xisha and Zhongsha Islands,right target areas should be selected for breakthrough in key area through geophysical prospecting and regional research.We should follow the policy of the government to seek for joint development in the area of Nansha Islands.
