FIELD: oil industry. ^ SUBSTANCE: method includes taking oil from product wells, forcing water into force wells, maintaining face pressure at product wells higher than oil pressure of gas saturation, and at force wells - lower than pressure of bed hydraulic fracturing. Well operation technological modes are measured, pressure restoration curves are taken, filtering parameters of bed are determined. According to invention for each of wells, with consideration of their interference, partial derivative of total deposit oil debit is determined on basis of face pressure. Then by utilizing partial derivative of total oil debit on basis of face pressure graph of total oil extraction is built dependent from totals of absolute values of depression and repression. On basis of characteristic bend on the graph optimal mode of technological effect on deposit is determined and realized. ^ EFFECT: higher oil yield, higher efficiency. ^ 1 ex, 1 tbl, 1 dwg |
