Spectrophotometric determination of copperⅡ in oil sample with 5′-nitro-salicylfluorone;
5′-硝基水杨基荧光酮分光光度法测定油样中铜Ⅱ
The comparability of two chromatographic fingerprint maps of different oil samples was calculated using the vector angle method.
结果表明 ,在相同的仪器设备下 ,同一油样多次实验结果的相似度 (或平均值 )约为 98% ,这可作为油藏流体连通性的上限。
Oil sample taken from oilfield or pipeline has a high water cut,so,dehydration is of necessity when the test is carried out on a physical and rheological behavior of oil sample in laboratory.
从油田或管道中取出的油样具有很高的含水率,在进行实验室原油物性和流变性实验时还需脱水。
