目的研究阳极距离对脉冲电流阴极保护深度的影响.方法:在5.0×0.5×0.5m的水池中,建立均匀NaCl溶液介质模拟油井套管阴极保护体系,采用挂片法,研究了阳极距离对方波脉冲电流阴极保护深度的影响.结果:在阴极保护系统中,阴阳极距离存在一个临界值D临,只有阴阳极距离大于D临时,阴极才有可能全线得到有效保护.结论在脉冲电流阴极保护系统中,阳极距离是影响保护深度的重要因素.如果由于现场条件限制,阳极不可能分布得足够远,那么需采用别的办法来增加保护深度.

Objective to study the influence of anode distance on the depth of pulse current cathodic protection. Method in 5.0×0.5×0.5 pool, establish uniform medium NaCl solution simulated cathodic protection system, by using bolt, anode distance each other wave pulse current cathodic protection is studied the influence of the depth. Results In the cathodic protection system, there exists a critical value D polar distance of cathode and anode is only temporary, anode distance is greater than the D cathode could all be effectively protected. Conclusion in the current cathodic protection system, the anode distance is an important factor to impact protection depth. If the site conditions, anode distribution could not far enough, so need to use other ways to increase the protection depth.
