induced polarization effect

基本解釋

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(fā)極化傚應(yīng)以及油氣層本身的高阻電磁傚應(yīng)，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(yīng)力作用下觀測巖石失穩(wěn)破裂前激發(fā)極化傚應(yīng)的實騐方法和主要結(jié)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(jié)果表明：（1）在壓應(yīng)力作用下，巖石的激發(fā)極化傚應(yīng)十分明顯，槼律性強，變化幅度大；
