【摘要】 针对传统原油检测计量效率低及测量误差大等实际问题,根据油水界面的特点,基于电磁波在多相介质中传播的差异特性,提出了一种新型原油储罐油水界面测量系统,采用矩阵电磁传感器来实现对原油层、油水混合层和水层的检测。实际投运表明,该系统能够在线实时对储罐液面进行测量,液面总高度的测量误差为±5mm,多相介质界面参数的测量误差为0.25%。更多还原

【Abstract】 Considering the inefficiency and error in present crude oil measurement,and basing on the difference of electromagnetic wave propagation in multiphase medium,a new measurement system for crude oil storage tank water-oil interface was proposed to detect crude oil,water-oil and water layers by employing a matrix electromagnetic sensor.The application shows that a ±5mm measurement error for liquid height and a 0.25% measurement error for multiphase medium can be achieved by this system.更多还原
