Title:
OIL-GAS-WATER THREE-PHASE FLOWMETER
Document Type and Number:
WIPO Patent Application WO/2017/133588
Kind Code:
A1
Abstract:
Disclosed is an oil-gas-water three-phase flowmeter. The oil-gas-water three-phase flowmeter comprises a main pipe (1). A mixer (2), a pressure sensor (3) and a gas-liquid two-phase flowmeter (4) are successively disposed on a horizontal straight section of the main pipe (1). A flow computer (5) is disposed on a gauge head of the gas-liquid two-phase flowmeter (4). A sampling bypass pipe (6) is connected to the horizontal straight section of the main pipe (1) between the mixer (2) and the gas-liquid two-phase flowmeter (4). A flow control valve (7) and a tubular column-type cyclone separator (8) are successively disposed on the sampling bypass pipe (6). A gas-phase pipe (9) at the top of the tubular column-type cyclone separator (8) is connected to a gas flowmeter (10), and the bottom of the tubular column-type cyclone separator (8) is connected to a liquid-phase outlet pipe (11). A mass flowmeter (12) or a water-in-oil meter (12) and a liquid-phase flowmeter (16) are disposed on a horizontal straight section of the liquid-phase outlet pipe (11). The flow computer (5) is connected to the pressure sensor (3), the mass flowmeter (12) or water-in-oil meter (12) and the liquid-phase flowmeter (16) respectively, via a data line.
