摘要
无线电磁法（WEM）是上世纪90年代发展起来的一种新的人工源电磁探测技术，它通过一个固定大功率发射台发射0．1～300Hz超低频／极低频电磁信号来探浸ll地下地质结构．国内对WEM法的应用已做了大量的理论和实际试验工作，例如，大功率发射台辐射的电磁场计算，不同距离电磁信号发射接收试验，油田深部结构探测试验等．从试验的结果看，WEM法在提高电磁测深数据质量上具有很大的优势．
Wireless Electro-Magnetic Method（WEM）is a new artificial source electromagnetic sounding technique developed in 1990s, which uses a fixed high-power transmitting station as an artificial signal source to provide a stable SLF/ELF electromagnetic signal in the range of 0.1 Hz to 300 Hz for exploring geologic structure. Vast theoretic and experimental research for the WEM application has been done in our country. For example, the calculation of electromagnetic field produced by the high-power transmitter, the receiving of signals transmitted from different distances, the probing for deep structure of the oil field etc. From the results of research we can see that the WEM does have large advantages in improving the data quality for electromagnetic prospecting.
