The invention relates to a flowmeter of oil well two phases and metering method thereof. The flowmeter comprises a shell (1), an inlet (3) and an outlet (4) are formed in the shell (1), the shell (1)is internally provided with a metering inner cavity (2), the inlet (3) is communicated with the metering inner cavity (2), the metering inner cavity (2) is internally provided with a valve element (6), the upper end of the valve element (6) is provided with an electromagnetic coil (7), the electromagnetic coil (7) is connected with a control circuit, the valve element (6) is provided with a lowervalve (8) and a upper valve (9), the lower valve (8) is used for controlling whether the bottom of the metering inner cavity (2) is communicated with the interior of the shell (1), the upper valve (9)is used for controlling whether the top of the metering inner cavity (2) is communicated with the interior of the shell (1), the metering inner cavity (2) is further provided with a liquid level sensor (10). The flowmeter can achieve multiple measurement purposes simultaneously and cannot cause blocking, and the operation is sensitive and reliable.
Description
technical field [0001] The invention belongs to the technical field of measurement, and relates to an oil well flowmeter and a measurement method thereof, in particular to an oil well two-phase flowmeter and a measurement method thereof. Background technique [0002] Because crude oil contains water and gas, and the flow rate is small, the working conditions of the wellhead of the oil production well are complicated, and the measurement of the liquid production at the wellhead has always been a difficult problem. [0003] At the same time, when the gas content in the crude oil is relatively large, it is also desirable to know the gas content in the crude oil. Moreover, sometimes it is necessary to know the water content of crude oil, temperature, pressure of oil well pipeline, etc. In this way, it is often necessary to use a variety of different flowmeters, making the measurement very cumbersome, and the measurement accuracy is relatively low [0004] In view of the above-...
