本实验试图通过单井垂向全空间四极对称布极装置,测量地下灰岩电阻率随时间的变化情况。结果表明,这种方法较能有效地消除地表层干扰的影响,从而获得了年变幅度低于2.0％的平稳灰岩电阻率资料。
This experiment attempts to measure the variation of the resistivity of the limestone in the ground with time through the single-well vertical full space quadrupole symmetric cloth pole device. The results show that this method can effectively eliminate the influence of surface disturbances and obtain stable limestone resistivity data with annual variation less than 2.0%.
