摘　　要："阵列瞬变电磁方法(ATEM)"是建立在高分辨率基础上的可控源时域多分量电磁勘探方法。通过对所观测的多分量时域电磁信号进行信息提取、处理与反演,可获取剩余油电性与极化率特征的空间分布状态,从而达到应用电磁法直接或间接寻找剩余油的目的。该方法具有成本低、速度快、野外施工简便等优点,可用于剩余油边界的探测或预测,以及井周油藏边界的动态监测。对指导下一步的勘探开发部署,降低油田开发生产成本,提高采收率,具有重要意义。Array transient electromagnetic method（ATEM ）is a high resolution electromagnetic method of exploring multi--component controllable source time domain. This method boasts of locating remaining oil directly or indirectly by obtaining the space distribution of remaining oil＇s electric property and polarizability through data extraction, mining and inversion of the electromagnetic signals caught in the multi--component time domain. It＇s cheap, fast and easy to practice in field and furthermore it can be used to explore or predict the periphery of remaining oil and monitor the reservoir borders around wells in real time, Therefore ATEM is of great importance in planning and supporting the next step of exploration, lowering production costs and improving recovery ratios.
