FIELD: oil producing industry. SUBSTANCE: method for operation of oil wells includes withdrawal of fluid from well by pump up to bottom hole pressure below the formation pressure. For this purpose, pump capacity is varied to attain the steady-state conditions. In so doing, distance from well bottom hole to the line of degassing is measured up to the moment of reaching by the degassing line the position corresponding to the pump steady-state conditions. This distance is maintained constant for the entire time of formation development by regulating the pump capacity. EFFECT: higher efficiency.
