Through simulation experiment in the laboratory, it follows that in case the water electric resistivity is appoximately egual to the cathode-anode area ratio, anodes should be buried underground with a depth of 3000 cm-5000 cm, the way of anodes combination is connection in series-parallel, and it would come into being the bigger electric current output and the good potential distribution. The suitable spacing between of anode and cathode ranges around 900 cm. %K casing %K deep well %K sacrifice anode %K cathode-anode spacing %K corrosion control
