induced polarization effect

基本解释

Both the induced polarization effect above oil & gas reservoirs and the innate high resistance electromagnetic effect of reservoir cause the existence of transient electric field.
油气藏上方的激发极化效应以及油气层本身的高阻电磁效应，都能导致瞬变电场的存在。
This paper introduced the experimental method and main results of induced polarization effect observed before the rupture of the instable rocks under the action of compressional stress.
本文介绍了在压应力作用下观测岩石失稳破裂前激发极化效应的实验方法和主要结果。
The experimental results show: 1. Under the action of the compressional stress, the induced polarization effect of rocks is very clear, with obvious regularity and large variation amplitude;
实验结果表明：（1）在压应力作用下，岩石的激发极化效应十分明显，规律性强，变化幅度大；
