DEVICE FOR SIMULATION OF ELECTRICAL PROPERTIES OF ROCK Russian patent published in 1996 - IPC

FIELD: geophysical investigations. SUBSTANCE: device is used for checking characteristics of downhole equipment. For simulation of electrical properties of rock it has external tube filled with electrolyte. One part of tube is made of metal, other part - of dielectric. Located inside of this tube is a set of dielectric tubes with through holes. Internal tubes are installed at different clearances relative to each other. Dielectric tubes are of different thickness. Bore area of holes at local sections is various. Through holes of adjacent tubes are shifted. EFFECT: high accuracy. 1 dwg
