FIELD: gas-and-oil industry.
SUBSTANCE: device consists of flow line communicated with formation fluids. Also the flow line includes the first section containing the first conducting zone, the second section containing the second conducting zone and an isolating section located between the first and second sections and preventing direct electrical connection between the first and the second section. The first circular core and the second circular core surround the flow line around the first and the second sections correspondingly. Additionally, the first circular core induces electrical current in fluid in the flow line, while the second circular core is designed for measurement of electrical current induced in fluid in the flow line. The electron block is designed for control over the first and the second circular cores.
EFFECT: increased reliability of method and device for measurement of specific resistance in formation testers or similar downhole equipment.
