摘　　要：海井电磁法是将电偶极子发射源放置在海水中,在海底油气井中接收电磁场响应以监测海底油气藏开发过程中分布,以较低的成本监测海底油气藏开发的技术。尽管该方法在我国还没有公开的研究资料,但在国际上,海井电磁已经逐渐受到海洋油气开发研究的关注,成为一个新的研究技术。针对此方法,在忽略井套管影响下,试算了多个海底电阻率一维模型;并讨论分析了不同方向的电偶极子源的响应特征。试算结果表明海井电磁法在油气监测上具有非常大的潜力和优势。Placing a dipole source into sea and measuring the electromagnetic response in a metal case of oil drilling well is a new low-priced method to monitor the underground dynamic conductor method. Although there is no open research data about this method in China, it is gradually becoming a new technology and research field in internationally. Several one dimensional mode and neglect the influence of metal well wre calcu｜ated. Base on the discussion and analysis, it seems that sea to borehole electromagnetic method has huge potation and advantage.
