Using laboratory electrochemical simulation experiment, namely the polarization curve technology and electrochemical impedance test technology, the corrosion of copper, 20
# steel, X80 line pipe steel were researched in soil solution of Liaohe oilfield typical plot. The corrosion rule of
this three different metal material in soil preparation solution was tested. Experimental results show that copper corrosion resistance is the strongest, X80 line pipe steel next and 20# steel corrosion resistance is the weakest in soil preparation solution.
