METHOD AND SYSTEM FOR MEASURING PARAMETERS IN WELL Russian patent published in 2020 - IPC E21B47/06 

FIELD: measuring equipment; drilling of wells.

SUBSTANCE: group of inventions relates to means of measuring parameters in an oil well. In particular, method of measuring parameter in well is proposed, which includes: connection of measuring instrument to first end of cable and connection of vector analyzer of circuits with second end of cable; lowering of measuring instrument into well; signal generation by vector network analyzer and signal transmission by cable to measuring device; swinging frequency of signal in specified range with transmission of signal to measuring device; determining a resonance frequency of at least one sensor located in the measuring device; and calculating a parameter from the resonant frequency of said at least one sensor using a calibration system which includes a polynomial selection calibration mechanism.

EFFECT: technical result is providing reliable measurement of parameters in well by instrument, which can withstand high temperatures and pressure in well.
