Abstract:The paper presented a new imaging method of wave-equation continuation for MT-imaging by electromagnetic reflection function continuation for MT characterized by simple practice,few acquired conditions and high-precious imaging,simply called as IRC.First the paper introduce the IRC theory in 1-D medium,deduced electromagnetic reflection function of MT that represented by ratio between upgoing and downgoing electromagnetic waves;then the operational feature and steps of imaging method of reflection function continuation for MT are given;finally using the method and pseudoseismic interpretation method to compute the model and real data near borehole in order to expound the feasibility and practice of the method.The method not only makes interface correct imaging,but also computes such parameters as true impedance etc,not affected by upper interfaces.
