摘要
海洋电磁法勘探能够成为海洋油气勘探技术中必需的步骤,能够突破传统非地震勘探方法只能作为早期构造勘探中无关紧要的方法,其原因在于海洋电磁勘探技术能识别高阻油气藏,从而达到直接找油气(DHI—Direct Hydrocarbon Indicator)的目的。通过当前海洋电磁法的调研,对海洋电磁的基本原理、采集技术、处理解释技术以及所面临的挑战和发展前景等几个方面进行了阐述,展现了目前国际海洋电磁勘探技术及新进展。
Recently,marine Controlled Source ElectroMagnetic(CSEM)method and technology have been deployed as an aid to prioritizing previously identified targets,or making simple drill-or-not-drill decisions.It breaks through the treatment that traditional non-seismic method can only be used as an auxiliary exploration method in the early stage of oil and gas prospecting,and is unimportant or unnecessary.Why is that It is because marine CSEM technology can be used as the direct hydrocarbon indicator.In this paper,we reviewed the fundamental method of marine CSEM,and discussed the data acquisition,processing,and interpretation of marine CSEM,as well as the challenges and difficulties it faces today.We also introduced the new development progress of the marine CSEM technology around the world in recent years.
