摘要
通过室内水槽中模拟井中点源供电、套管供电以及没有套管点源供电,对井中直流电场分布规律做了研究。同时,针对井中电偶极源供电时的周围地层电流分布又做了一维数值模拟。为进一步研究井中偶极供电时油井周围地层场的计算奠定了基础,对野外实际生产有一定的指导意义。
In this paper, we investigate the direct-current （DC） electric-field distribution in borehole ground simulated by a point source, which is located in borehole equipped with cast, or directly contacted with cast or simply in water trough respectively. Meanwhile, we conduct 1D numerical simulation regarding electric current distribution of surrounding layers on condition of electric dipole-source-excited within borehole. It lays a foundation for calculation of electrical field of surrounding medium, and provides guides for field production.
