Abstract

The invention relates to a combined multiphase flow fluid measurement system. The system comprises a venturi and microwave sensor integrated module, an electromagnetic tomography module and a data acquisition and processing module; the venturi and microwave sensor integrated module comprises a venturi part and a microwave sensor part; the venturi part comprises a venturi tube, and a pressure tapping module, a pressure sensing module and a temperature sensing module which are arranged on the venturi tube; the venturi tube comprises an upstream pipeline, a contraction section, a throat part, anexpansion section and a downstream pipeline; and the electromagnetic tomography module is positioned at the throat part of the venturi tube and is close to the upstream pipeline. According to the invention, the electromagnetic tomography technology, the microwave detection technology and the venturi are combined, and the multiphase flow and the moisture content are solved by utilizing the signal combination of each sensor; the whole measuring system has no parts invading the interior of the pipeline, has no radioactive source, and has the characteristics of safety, environmental protection, non-invasion, non-contact, no flow pattern influence and no scaling influence.

Description

technical field [0001] The invention relates to a combined multiphase flow fluid measurement system. Background technique [0002] Since the early 1980s, how to measure oil-water-gas three-phase flow mixture has become a problem of interest to the petroleum industry. The oil phase in the oil-gas-water multiphase flow refers to the liquid hydrocarbon phase in the oil well output fluid, the gas phase refers to natural gas, light hydrocarbon, and non-light hydrocarbon gas, and the water phase mainly refers to mineralized water, and there is also a very small amount of solid phase (sand, wax and hydrate, etc.). Multiphase flow measurement is of great significance in the process of petroleum production and transportation. [0003] In order to achieve optimal oil / gas field productivity and life, operators need to be able to regularly monitor the output of each well in the oil field to optimize production operations. The optimal production operation of oil reservoirs in the petr...
