摘　　要：井间电磁成像技术是监测和描述开采期间油储层动态变化的重要手段之一,它可为分析井间剩余油分布,提高油田滚动勘探和开发中打高效调整井提供重要依据.而井间电磁成像技术的应用难点之一是如何开发出高效的成像处理软件,实现对复杂地层进行高分辨率的井间电磁反演.本文给出了磁场振幅和相位的视电导率反演迭代方法.An important problem in petroleum production is the development of a reservoir model which guides the drilling of wells and the management of the field. The surveys of low-frequency crosswell EM has adequate power to monitor the deposits of oil and natural gas with the transmitters in transmitting well and receivers ira another wells around up to several hundreds meters apart. It has a longer range of detection and gets more information of deposits than the one well logging. For practice we chose the amplitude and the phase as the examining components. Here we give the ways of interpreting the logging data of the medium conductivity which is one of the noduses of the application of the crosswell EM technique.
