FIELD: oil and gas extractive industry.
SUBSTANCE: method includes measuring average value of flow during adequately picked time for each well of group with successive - according to given program - connection of wells to measuring device and following recalculation of debit to day productiveness. At the same time the most dynamic well of group is selected on basis of one of most unstable parameters. Numeric value of relative quadratic error δ3 of average flow value m(q) is set and recorded in memory of computer, for example, industrial controller. Period of scanning for this well is determined. With same period remaining wells of the group are scanned. Scanning period for each I of them is corrected by comparison of current - actual - relative average quadratic error δmi of average flow value q1 with previously set δ3 from conditions δ≥δ3(1+K); δmi≤δ3(1-K), where K - coefficient for limiting changing range δmi, defining necessity of correction of scanning period for I well towards decrease or increase. If switching moments for measurements of two or more wells from group coincide, order of their scanning is set in accordance to decrease of productiveness of these wells.
EFFECT: higher efficiency.
