DEVICE FOR MEASURING RADIAL INFLOWS OF LIQUID IN OPERATING OIL WELLS Russian patent published in 1999 - IPC

FIELD: oil production industry. SUBSTANCE: device is used in hydrodynamic investigations of oil wells and particularly in flow rate metering. In device, mechanical deviations and vibrations of membrane 5 which takes only radially directed inflows of liquid are transmitted to magnetic inductor. Inductor when interacting with magneto-electric component initiates electric signals in induction coil which are formed in electronic unit and are transmitted to surface by cable. Character of electric signals transmitted to surface as to their intensity and frequency characterizes intensity and character of radial inflows of liquid in well. Aforesaid embodiment of device is specified for higher sensitivity, reliability and simplified design. EFFECT: higher efficiency. 1 dwg
