METHOD AND DEVICE FOR MEASURING DISCHARGE OF OIL Russian patent published in 1995 - IPC

FIELD: oil production. SUBSTANCE: special tank is filled with antifreezing agent till achieving preset level. Then separator is filled with oil liquid till achieving preset level in measuring tank, which is mounted inside the separator. Time of filling of separator, level of oil liquid in the separator and pressure differential are measured. Pressure differential is created by antifreezing agent column and oil liquid in separator. After that the separator is dumped. Discharges of oil, water, and oil liquid are calculated according to relation, given in description of the invention. Device has separator 4, measuring tank 3, special tank 6, actuating mechanisms 2, 8 and 10, rectifiers 16, 17, and 18, differential pressure gauges 12 and 23, three pressure transducers 13, 14, and 24, control unit 9, registration unit 22, pipe-line 1, fill and drain lines 15 and 19 correspondingly, collector 7. EFFECT: improved precision of measurement. 2 cl, 1 dwg
