由电容传感器和伽玛射线密度计组合起来的一种非介入式多相分数计量仪已经由在挪威卑尔根市的 Che·Michelsen 研究所(CMI)研制出来。室内试验表明,该计量系统可以测定完全混合的油、气、水流体的组成,对每种组分测量的不可靠度好于±3%。谈仪表的工业样机还成功地完成了在英国陆基油田的现场试验。 A non-intrusive multiphase fraction meter, combined by a capacitive sensor and a gamma ray densitometer, has been developed by the Che Michelsen Institute (CMI) in Bergen, Norway. Laboratory tests show that the system can measure the composition of fully mixed oil, gas and water fluids with unreliability of ± 3% measured for each component. Industrial prototypes for instrumentation have also successfully completed field trials in land-based oilfields in the United Kingdom.
