    摘要: The effects of shaliness on the electrical resistivity (or conductivity) of earth formations is determined by obtaining a relationship between dielectric constant and a conductivity parameter that is a function of shaliness, measuring the dielectric constant of the earth formation of interest and using the relationship between dielectric constant and the conductivity parameter to determine the effects of shaliness on resistivity. The dielectric constant of portions of formations can be determined in-situ by electrical measurements, or by obtaining earth cores and subjecting the cores to electrical measurements.

    摘要: Apparatus for measuring the dry unit weight of a soil, either directly or with reference to a known soil variable (e.g., the Proctor density) by means of a measuring probe containing two electrodes in the soil under investigation. The measuring probe is energized with a constant a.c., voltage, and is connected in series to a measuring resistance at which a voltage drop occurs proportional to probe current (I). The voltage tapped at measuring resistance overlaps a continuously adjustable part of the said constant a.c. voltage, and, in a phase-sensitive rectifying indicating device, a proportion, continuously adjustable from zero, of the sum voltage obtained by the superposition is superposed on a second component, continuously adjustable from zero, of the constant a.c. voltage.
