N2 - An important problem of oil well diagnostics is to quickly determine changes in the amount of liquid entering the well (flow rate), and the ratio of the amount of water to the amount of liquid (water cut). To calculate these parameters, thermodynamic measurements (temperature, pressure) can be used at the wellhead and downhole of the well, as well as garlands at the wellhead of sensors 10-20 meters long, with a frequency of 1 meter, for more information. The article presents a comparative analysis of algorithms for determining these parameters based on the solution of the inverse problem. The results of numerical calculations are presented.
