岩石在压力作用下,用四极法测定不同方向上的视电阻率变化。讨论了测量结果,结论是对于水饱和岩石的视电阻率,在压力开始作用时,一般说来是上升的;裂纹对它们的影响要比毛孔变化对它们的影响厉害;每有破裂,视电阻率就有较大幅度的下降。视电阻率变化的方向性特征并不明显。
Rock under pressure, using the quadrupole method to determine the apparent resistivity changes in different directions. The results of the measurements are discussed and concluded that the apparent resistivity of water saturated rocks generally increases as pressure begins to act; the effect of cracks on them is more pronounced than that of pores; each time the apparent resistance There is a more substantial rate of decline. The directional characteristics of apparent resistivity change are not obvious.
