FIELD: oil producing industry. SUBSTANCE: gathering system includes measuring group units, booster pumping stations with water separator, group pumping stations for maintenance of formation pressure, oil and gas lines, waste water lines and central gathering station. System is divided into several autonomous units N including booster pumping station with water separator at inlet and group measuring units connected with it and group pumping station with adjoining wells and pipe lines. Oil from booster pumping station is transported together with gas by means of gas-and-liquid discharge pumps. Number of autonomous units of oil field is equal to N=n-b, where n is total number of group pumping stations of oil field and b is number of group pumping stations of oil field which are supplied with water directly from central oil gathering and preparation station. EFFECT: simplification of system; enhanced reliability. 1 dwg
