【摘要】：油气开采及油气运输中流体不分离计量是实现低碳生产的有效途径,气液两相流检测技术是实现这一目标的关键技术基础。利用近红外光谱技术作为研究测量方法,在水平管道上设计沿两相流流动方向进行测量的气液两相流相含率检测装置,将原有探头径向放置测量的方式改为沿流体流动方向进行测量,提高被相应的接收探头接收比例,达到准确测量的目的。利用计算流体动力学(computational fluid dynamics,CFD)仿真软件,优化装置结构。在新型测量装置上完成多个工况点的实验测试,得到相含率与近红外测量电压信号之间的数学模型,且相对误差分布在0.11%以内,为今后气液两相流不分离检测提供一种新方法。
[Abstract]:Fluid separation and metering in oil and gas production and oil and gas transportation is an effective way to achieve low carbon production. Gas liquid two phase flow detection technology is the key technology foundation for achieving this goal. By using near infrared spectroscopy as the research method, phase holdup detection device of gas-liquid two-phase flow along the direction of the design of measurement in horizontal pipe flow, the radial approach to place measurement measured along the direction of fluid flow, improve the corresponding receiving probe ratio, achieve accurate measurement purpose. The structure of the device is optimized by using computational fluid dynamics (CFD) simulation software. The experiment of multiple operating points is completed on the new measuring device, and the mathematical model between the phase holdup and the NIR measurement voltage signal is obtained. The relative error is less than 0.11%, which provides a new way for the future gas liquid two phase flow separation.
