Embodiment Construction

[0018] The detailed description and technical content of the present invention are described below with the accompanying drawings, but the accompanying drawings are only provided for reference and description, and are not intended to limit the present invention.

[0019] Such as figure 1 As shown, the mobile oil well metering device includes a gas-liquid separator 5, a tipping bucket flowmeter 8, and a liquid accumulation barrel 9. The gas-liquid separator is connected to the liquid accumulation barrel through its own gas pipeline 6, and the gas-liquid separator Connect the tipping bucket flowmeter through its own liquid pipeline 7, and then connect the tipping bucket flowmeter to the liquid accumulation bucket. The liquid produced in the oil well enters the gas-liquid separator through the liquid inlet pipeline 3, and the gas and liquid are separated in the gas-liquid separator. The liquid measured by the tipping bucket flowmeter enters the liquid accumulation barrel and mixe...

Abstract

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.

Description

technical field [0001] The invention relates to auxiliary equipment for metering production of oil production wells in the petroleum industry, especially a mobile oil well metering device. Background technique [0002] Oil field industry In high-pressure and low-permeability oil fields, due to imperfect injection-production well pattern and high formation pressure, the formation water flooding effect is poor, and some oil wells have low production and low liquid. Due to the influence of its own production capacity and the current status of the ground, most wells cannot be produced in separate metering stations. Therefore, production methods such as continuous water mixing process and peripheral well penetration pipelines are used for production, and the output fluid of a single well cannot be measured separately , in order to accurately grasp the liquid production rate of a single well, grasp the production change of a single well, and formulate reasonable and effective me...
