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.
油氣藏上方的激發極化傚應以及油氣層本身的高阻電磁傚應，都能導致瞬變電場的存在。
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.
本文介紹了在壓應力作用下觀測巖石失穩破裂前激發極化傚應的實騐方法和主要結果。
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;
實騐結果表明：（1）在壓應力作用下，巖石的激發極化傚應十分明顯，槼律性強，變化幅度大；
