Movable oil well metering apparatus

The invention provides a movable oil well metering apparatus which comprises a gas-liquid separator, a tipping bucket flow meter and a liquid accumulation barrel, wherein the gas-liquid separator is connected to the liquid accumulation barrel via a self gas circuit pipeline; the gas-liquid separator is connected with the tipping bucket flow meter via a self liquid circuit pipeline; and the tipping bucket flow meter is connected to the liquid accumulation barrel. Produced liquid of an oil well enters the gas-liquid separator through a liquid inlet pipeline and is subjected to gas-liquid separation in the gas-liquid separator; and the liquid after metered by the tipping bucket flow meter enters the liquid accumulation barrel to be mixed with gas, and then enters an oil well production flow via a liquid outlet pipeline for delivery. The tipping bucket flow meter is further connected with an integrating instrument. A gas meter and a pressure gauge are arranged on the gas circuit pipeline. A safety valve is arranged on the liquid circuit pipeline. The device can effectively reduce well string, accurately meters well stop time of yield, increases a well startup time rate, improves metering accuracy of the output liquid, reduces potential safety hazards and environmental pollution and achieves efficient, accurate and safe purposes.
