摘要
中国海洋物探工作开始于1960年。经过渤海的技术方法试验和北部湾综合物探生产试验,然后在各个海域全面铺开,先后发现了渤海、北部湾、南黄海、珠江口和东海陆架等新生代沉积盆地及其中的局部构造,并经钻探见到了工业油气流或油气显示。 以寻找油气资源为主要任务的海洋物探,不仅在引进技术装备、完善勘查方法、提高处理与解释水平等方面作了大量工作,形成了一定的规模,而且进一步开展了海域内的深部调查、工程地质条件调查以及深海大洋多金属结核调查,为全面开展海洋地质研究工作奠定了基础,为维护我国海洋权益和发展海洋地质科学技术作出了重要贡献。
Abstract
China’s marine geophysical exploration started in 1959. After the crucial test for confirming the validity of the techniques used in the Bohai Sea and the integrated geophysical trial production in the Beibu Bay, the exploration was fully under way one after another in each sea area. The Cenozoic sedimentary basins of the Bohai Sea , the Beibu Bay, the Pearl River Mouth, the continental shelf of East China Sea, etc., as well as the local structures located in the above basins were discovered in succession. Commerical oil/gas pools and hydrocarbon indications were obtained and detected through drilling.The marine geophysical drilling, with searching for oil/gas sources as its major target, has done not only much work for the import of technology and equipment, the sophistication of survey technique and the improvement in processing and interpretation, but the survey itself has already been expanded to a fairly large dimension. Also, marine geophysical survey for deep structures, engineering geological conditions as weu-as multimetal pelagites are carried out. All of these have laid the foundation for the overall research of the marine geology. Significant contributions have been made to the protection of marine sovereign rights and interests, to the development of the marine geological science and technology.
