作者用几个不同的模型计算饱和盐水的沉积岩的复介电常数。采用独立的体系计算,在直流极限给出阿尔奇定律。胶结指数m取决于颗粒的形状,与试验符合。该理论与在1.1千兆赫时对熔结的玻璃球测得的介电常数及电导率值符合很好。通过具有特殊几何特性的质点(例如纵横比高的岩石),可以说明实验观察到的介电常数对含盐量及频率的依从性,以及在低频时介电常数会出现极高值的情况。沉积岩的介电与电导率值有严格界限,这也表明介电常数的数值很大是可能的。岩石与水交界处离子的极化,同样也会使介电常数上升到高值。
The authors used several different models to calculate the complex permittivity of sedimentary rocks saturated with saline. Using an independent system of calculations, Archie’s law is given at the DC limit. The cementation index m depends on the shape of the particles and is in accordance with the test. This theory is in good agreement with the measured values of permittivity and conductivity for sintered glass balls at 1.1 GHz. With particles of specific geometry, such as rocks with high aspect ratios, experimental compliance of the observed permittivity with respect to salt content and frequency, as well as the extremely high dielectric constants at low frequencies, can be illustrated. The dielectric and electrical conductivity of sedimentary rocks have strict limits, which also shows that a large number of dielectric constant is possible. Polarization of the ions at the rock-water interface also causes the dielectric constant to rise to high values.
