摘要
石油工业测井计量站建立的C/O刻度装置,以纯柴油作为100%含油饱和度为标准来进行1,3-丁二醇模拟流体等效含油饱和度的计算,通过流体中C元素与O元素的摩尔百分比来实现不同的饱和度。由于尚未找到稳定性、准确性符合要求的C/O标准仪器,无法采用"用实物标准传递"的方法开展溯源。叙述拟采用"等效饱和度"公式,通过理论模拟计算来实现溯源。
The carbon oxygen ratio calibration device in logging measurement station takes the oil saturation of pure diesel oil as 100% oil saturation in the calculation of the equivalent oil saturation of 1,3- butyl glycol simulation fluid, and different oil saturation is obtained by different mole ratio of carbon element to oxygen element in the simulation fluid. The quantity value traceability of the measurement method can not be carried out by ＂physical standard delivery＂ since a C/O standard instrument with ideal stability and accuracy is not found. It is put forward that the quantity value traceability is realized the by theoretical simulation calculation using ＂equivalent oil saturation＂ formula.
