试论中国海的地球物理工作

SOME COMMENTS ON GEOPHYSICAL WORK OF CHINA SEAS

中国海纵跨42个纬度,与 8 个相邻和相向的国家存在着划界问题。划界谈判关系到国家的主权和权益,而其中更关键的则是资源,特别是海底油气资源。中国海的油气资源丰富,过去 40 多年地质地球物理工作已发现一系列新生代陆相沉积盆地,现在更进一步认识到前新生代海相残留盆地的存在,尤其是近年世界油气勘探往深水盆地发展的趋势,都已经向地球物理提出更高要求。此外,随着国家经济社会的迅速发展,环境与工程必然向地球物理提出更多的任务和更高的要求。与此同时,从国家安全的角度出发,保卫中国海还必须大力发展军事地球物理学研究。

China seas span 42 latitude degrees and contact with eight countries. Sea demarcation according to the United Nations Convention on Law of Sea has a bearing on the state sovereignty and rights and interests, and here the most important thing we should mention is resources, especially the submarine oil resources. China seas are rich in oil resources. The past four decades' geophysical work has discovered a series of Cenozoic continental sedimentary basins and also proved the existence of pre-Cenozoic marine relict basins. Recently, petroleum explorations in the world are going towards deeper and deeper waters, which requires more and higher geophysical work. In addition, with the rapid development of national economy and society, environment and engineering will ask for more tasks and higher requirements of geophysics. Meanwhile, from the viewpoints of state safety, military geophysics must be enforced to safeguard the China seas.
