Summary:oil and gas industry. SUBSTANCE: proposed method can be used in gas-lifting operation of wells fitted with installations of plunger lift. Well is brought to stop, pipe and hole clearances communicate with well-head. Level of fluid is reduced by value permissible for condition of creation of maximum depression in pool. Face and well-head pressures in pipe and hole clearances are recorded. Curve of inflow of fluid is plotted by difference of graphs of face and well-head pressures. Taking into account depression in pool one calculates operational parameters of well, in particular, depth of location of working hole and volume of fluid lifted during cycle of operation of installation of plunger lift. EFFECT: possibility of modeling of condition of operation of pool in process of survey. 2 dwg
