A Multiphase Fluid Measurement System

Abstract

The application belongs to the technical field of flow measurement, and in particular relates to a multiphase flow fluid measurement system. The existing oil-gas-water three-phase flowmeter is harmful to the environment and the human body, and the subsequent cost is relatively high. The application provides a multiphase flow fluid measurement system, including a flowmeter module, a water cut module and a data acquisition and processing module, wherein the flowmeter module is connected to the water cut module, and the flowmeter module is connected to the data The collection and processing module is connected, and the water content module is connected with the data collection and processing module; the flowmeter module is used to measure the virtual high flow rate of the fluid; the water content module is used to measure the phase holdup of water; The data acquisition and processing module is used to calculate the flow of each phase after collecting data. The modular design of the sensor is convenient for adjusting the position of the sensor according to different measurement requirements, and can provide fast, stable and reliable measurement and detection results for oil and gas wells under different working conditions.

Description

technical field [0001] The application belongs to the technical field of flow measurement, and in particular relates to a multiphase flow fluid measurement system. Background technique [0002] As an important strategic resource supporting the national economy and people's livelihood, oil and natural gas are involved in the measurement of multiphase flow in technical processes such as exploration, exploitation, transportation and processing. Therefore, it is of great significance to be able to accurately measure multiphase flow. [0003] At present, the multiphase flow measurement methods commonly used in oilfields mostly use the test well separator to separate the three phases of oil, gas and water, and then use single-phase instruments for separate measurement. Although this mode can guarantee a certain accuracy, because the separator is generally large in size and expensive, and the separation process is very time-consuming, this method cannot realize real-time online mea...

Problems solved by technology

Gamma densitometer uses the characteristic that gamma rays have different attenuation rates in different density media to estimate the mixing density of fluids. The disadvantage of this technical solution is that the radioactive source is harmful to the environment and the human body, and its production, Most of the use needs to be approved by the regulatory authorities, resulting in higher later costs
