摘要
通过室内模拟实验 ,考察了阳极埋入方式、阳极埋入深度、阴—阳极间距离及阳极间距对深井套管纵向电位的影响 .结果表明 ,对阳极采用深埋方式为宜 ,且阳极以串、并联组合方式连接 ,阳极埋入深度以 5 0~ 65m为宜 ;阴—阳极间距以 9~ 14m为宜 ,深井阳极串阳极间距以 3m左右为宜 .在该条件下 ,套管上的电极电位超出标准保护电位 -3 8mV 。
Through simulation experiment in the laboratory, anodes should be buried underground with a depth of 50 m to 65 m. The way of anodes combination is connection in series-parallel. The suitable spacing between of anode and cathode ranges from 9 m to 13.5 m. The spacing among the anodes ranges from 2.0 m to 3.5 m.
