摘要
本文针对目前油井套管阴极保护中存在的问题，提出一种新的数值方法以提供恰当的外加电压，通过计算套管外壁上的电位分布，为阴极保护方法提供科学的数学理论依据，克服以往各种测试方法的不足。
In this paper,a few problems to oil well cathodic protection approach are summarized,the new numerical method to supply proper impressed voltage is presented.By calculating the potential dlistribution of casing's outside wall,a basis of scientific mathematical theory is provided,so,raw matherials and reasources can be saved.
