摘要
In view of the characteristics of traditional central gradient IP method,such as high efficiency and less data amount,this paper puts forward the multiple electrode distance central gradient survey method.Using the existing multi-channel transmitter and receiver with a little additional work,this method can get more apparent resistivity and apparent polarizability data to realize 2D inversion imaging.The inversion results of modeling and measured data have shown that the multiple electrode distance central gradient survey basically has the same effect as the symmetric four-pole sounding,and at the same time can improve work efficiency multiply.So,the multiple electrode distance central gradient survey can be applied widely.
