FIELD: measuring equipment engineering, possible use for measuring flow and properties of solutions, in particular, in oil-gas extractive industry for controlling flow and properties of drilling and cementing agent during drilling of wells and their cementing.
SUBSTANCE: system contains indicators of pressure and temperature, device for measuring density of solution, device for measuring conductivity of solution, computing device, information display. Indicators of pressure and temperature, device for measuring solution density, solution conductivity meter and computing device are positioned in compact manner within one measuring module, installed in main pipeline; measuring module contains additionally device for measuring pressure drop on narrowing device, solution density meter is made in form of two-probe gamma density meter with low-background source of gamma-radiation, computing device provides, in accordance to given algorithm, for determining and computation of volumetric flow of solution, of mass flow of solution, of solution density, of electric conductivity or mineralization of solution, of solution temperature, of system pressure, content of solid phase in solution, well hydraulic losses coefficient; measuring module via information cable is connected to information display for controlling the process of drilling or cementing.
EFFECT: increased parameters being measured, increased reliability of system operation and decreased costs of same.
