Large-diameter injection-production same pipe bidirectional mixed-phase metering device and metering method

Abstract

This invention discloses a large-diameter bidirectional mixed-phase metering device and method for injection and production in the same pipe, relating to the field of industrial mixed-phase fluid measurement technology. The device includes a main body, a sunshade, a non-radioactive composite quantum light source, a quantum light detector, a quantum light flow computer, a front differential pressure tap, a rear differential pressure tap, and a power module. The main body has an internal throttling channel. The non-radioactive composite quantum light source emits quantum light beams of four energy levels. Based on quantum precision metering multiphase detection technology, it adopts quantum precision measurement technology, an internal throttling channel, and a dual differential pressure structure to achieve functions such as large diameter and bidirectional injection and production in the same pipe, enabling high-precision real-time monitoring and metering. The quantum light source emits photons of different energies. The absorption of photons by matter causes the photon energy to attenuate after passing through the matter. Combining the different absorption degrees of photon energy by different substances, it achieves high-flow-rate, high-gas-content, multiphase, real-time, and accurate bidirectional metering of gas storage injection and production.
