Abstract The in-situ visualization of flow in the opaque pipes and annulus is a major cause of concern for studying hole cleaning issues and multiphase flow patterns in the oil and gas industry. Electrical resistance tomography is one of the latest non-intrusive technologies, which can provide real-time cross-sectional images of multiphase flow patterns in opaque pipes and annulus. Most studies conducted using the ERT system in the area of multi-phase flow is limited to opaque pipes and two-phase systems. Therefore, in this work is the suitability of the ERT technology has been tested to examine the three-phase flow (air-liquid-solid) and solids cuttings transport in a horizontal flow loop annulus system at wide operating conditions. The effect of different eccentricities (0–50%), inner pipe rotation speed (0–120 RPM), liquid flow rates (164–373 kg/min) and air input pressure (0–0.8 bar) on solids concentration in the specified ERT zone was examined using ERT concentration tomograms.

使用电阻断层扫描 (ERT) 测量牛顿流体中穿过水平环空的固体岩屑传输

摘要 不透明管道和环空中流动的原位可视化是研究石油和天然气工业中的孔清洁问题和多相流动模式的一个主要原因。电阻断层扫描是最新的非侵入式技术之一，它可以提供不透明管道和环空中多相流模式的实时横截面图像。在多相流领域使用 ERT 系统进行的大多数研究仅限于不透明管道和两相系统。因此，在这项工作中，对 ERT 技术的适用性进行了测试，以检查三相流（气-液-固）和固体岩屑在宽操作条件下水平流动环路环空系统中的传输。不同偏心距（0-50%）、内管转速（0-120 RPM）的影响，
