Abstract

The invention relates to a light quantum detection system, a calculation method thereof and a light quantum multi-phase bidirectional flowmeter employing the system. The light quantum detection systemcomprises an emitter and a detection module, wherein the emitter and the detection module are arranged at two sides of a throttling element, the emitter is a light quantum source and is used for emitting light quantum, the throttling element is used for a fluid to pass through, the emitter and the detection module are arranged at two sides of a throat segment of the throttling element, the detection module is a detector array and comprises a plurality of detection units arranged in a matrix form, each detection unit is used for receiving light quantum penetrating through the throttling element, and the detection units are CZT detectors. The light quantum sub-source is used as the emitter, light quantum particle with different energy is emitted, and each detection unit is used for independently measuring single photon; and with the adoption of the CZT semiconductor detector array, the light quantum detection system is small in volume and higher in energy resolution, the application ofa physical collimator can be omitted, relatively good space resolution is achieved in measurement section, so that the measurement accuracy is improved.

Description

technical field [0001] The invention relates to the field of flow detection of multiphase fluids, more specifically, it relates to an optical quantum detection system and its calculation method, and an optical quantum multiphase bidirectional flowmeter adopting the system. Background technique [0002] As China is a big consumer of oil and natural gas, how to safely store related energy has always been the top priority of the country's energy work. Storage in gas tanks poses a greater safety risk. At present, underground gas storage is generally used to store gaseous oil and natural gas in China. There are many abandoned oil wells that have been exploited in China, and abandoned oil wells can be directly used as gas storage. [0003] Liquefied oil and natural gas is purchased from abroad and then gasified first, then the gaseous oil and natural gas is injected into the gas storage, pressurized and sealed, and when needed, it is exported from the gas storage, at the entrance ...
