X-ray 2D and 3-Phase computed tomography (CT) measurements of multiphase flows: digital reconstruction of multiphase flow maps suitable for high pressure applications

摘要

An X-ray 2D and 3-phase computed tomography (CT) device has been used within NEL's multiphase facility to identify multiphase flow structures and flow regimes for mixtures of gas, oil and water flows at low pressure. This paper demonstrates the application of this technology for the digital reconstruction of flow regimes and assessment of slugging frequencies. Experiments were conducted in a 4-inch section of horizontal pipework for mixtures of gas, oil and water at various superficial velocities. The X-ray 2D and 3-phase device is shown to be a valuable tool which is suitable for high pressure applications to quantify flow structures.
