Intelligent metering system for oil well produced liquid

The utility model discloses an intelligent metering system for oil well produced liquid, which comprises a three-phase separator for receiving the oil well produced liquid and separating the oil well produced liquid into gas, crude oil and sewage; the three mass flow meters are respectively arranged in the gas pipeline, the crude oil pipeline and the sewage pipeline at the rear end of the three-phase separator, and are used for measuring the mass flow of the corresponding medium in the pipelines in the storage process of the produced liquid of the oil well; and the three-phase storage tank is a closed horizontal storage tank and is provided with three relatively isolated cavities, namely a gas cavity, a crude oil cavity and a sewage cavity. According to the utility model, the oil well produced liquid is subjected to three-phase separation and is stored by the three-phase storage tank, so that a heating link and a tank reversing process are reduced, and the leakage risk can be effectively reduced through full-
