摘要

测井是通过地球物理探测器的下降和上升对井切口结构的详细研究。它常被用来测定地球深处的电导率。为了做到这一点,井的两侧加深电极,并将它们送入恒定电流的深处。然而,如果你使用自然或人工电磁波,就有可能在深处确定陆地岩石的介电渗透率。为此,首先在地球表面测量表面阻抗,然后在井内以一定频率测量电磁场,用相当简单的公式计算出地质体的电导率和介电渗透率。这样的测量可以通过标准测量系统进行,只增加一个狭窄的框架和电线绕组来测量磁场。

Using the Carotazh Method to Determine the Electrical Characteristics of the Earth’s Subsoil
Logging is a detailed study of the structure of the well incision by descent and ascent of a geophysical probe. It is often used to determine the electrical conductivity of terrestrial depths. To do this, the sides of the well deepen the electrodes, and they are fed into the depths of a constant electric current. However, if you use natural or artificial electromagnetic waves, it becomes possible to determine the dielectric permeability of terrestrial rocks at depth. To do this, the surface impedance is first measured on the surface of the earth, and then by measuring at a certain frequency of the electromagnetic field in the well hole, the electrical conductivity and dielectric permeability of terrestrial rocks are calculated by fairly simple formulas. Such measurements can be carried out by standard measuring systems, adding only a narrow frame with wire winding to measure the magnetic field.
