大功率海洋可控源电磁勘探系统装备性能及应用

The equipment performance and application of high-power marine controlled source electromagnetic exploration system

海洋可控源电磁法(MCSEM)在海底石油、天然气水合物、多金属矿勘探以及海洋环境地质调查等领域应用广泛,是一种重要的海洋地球物理调查方法。我国海洋地质调查受现有硬件装备、技术水平、资源条件等因素的限制,多年以来一直没有突破性进展。近年来,在国家863海洋技术领域重大课题支持下,我国在海洋电磁勘探装备、方法理论研究等领域都有了明显的进步。特别是由东方地球物理公司牵头负责的"十二五"863计划课题"深水可控源电磁勘探开发系统"在六所大学和两家企业的共同努力下,自主研发了我国首套大功率海洋可控源电磁勘探系统装备,并在南海某已知油气目标区成功进行了工业化应用,为进一步开展商业化应用奠定了基础。

Marine controlled source electromagnetic method ( MCSEM) is a kind of important marine geophysical methods which is widely used in such fields as petroleum and natural gas hydrate exploration in the bottom of the ocean, exploration of polymetallic nodules and marine environmental survey. However, China has been limited by the existing hardware, equipment, technical level, resource conditions and other factors which had made no breakthrough for many years. In recent years, with the field of marine science and technology innovation has been promoted to the national development strategic planning, the twelfth Five-year Guideline (863 plan) uDeep controlled source electromagnetic exploration and development system" led by Bureau of Geophysical Prospecting of China National Petroleum Corporation has been made substantial progress. With the joint efforts of six universities and two enterprises, the equipment of Chinas first large-power marine controllable source electromagnetic exploration system was developed. The complete set of equipment has been successfully carried out in the petroleum target area in the South China Sea, which lays the foundation for the next commercial application.
