摘要
摘要为了保证油气行业商品输送作业的可靠性,采用标定流量计对管道中流体的运动进行量化。本文的目的是验证瞬态时间法(TTM)校准安装在限制区域的油流量计,使用123i标记的油作为放射性示踪剂。传统上,根据标准ISO 2975- 7:20 77[1]的建议,在水介质中进行实验,TTM是通过将两个探测器定位在不同的位置来使用的。然而,在工业厂房中,并不总是能够按照ISO 2975-7推荐的距离安装探测器。本文提出的方法使用四个闪烁体探测器,每个探测器相隔0.30 m,并注入含有5.0 ml 123i标记油的三次注射。实验是在紊流剖面的油流钻机上进行的。结果的不确定度小于1.0%。
Validation of transient time method to calibrate oil flow meters in closed conduits using 123I as the radiotracer
Abstract To assure the credibility of commodity transfer operations in the oil and gas industry, calibrated flow meters are used to quantify the movement of fluids in the pipelines. The purpose of this paper is to validate the transient time method (TTM) to calibrate oil flow meters installed in restricted areas, using the 123I-labelled oil as a radiotracer. Traditionally, as proposed by the standard ISO 2975-7:1977 [1] for experiments in an aqueous medium, the TTM is employed by positioning two detectors at separate locations. However, in industrial plants, it is not always possible to install detectors at the distances recommended by the ISO 2975-7. The method proposed in this paper uses four scintillator detectors separated one from each other by 0.30 m and three injections containing 5.0 ml of 123I-labelled oil. The experiments were carried out in an oil flow rig with a turbulent flow profile. The results have reached an uncertainty which is lower than 1.0%.
