摘　　要：塔里木油田哈得采油气区在2022年1—2月原油含水准确率从92%下降至75%。在油藏类型不变的情况下,原油含水不会出现大幅波动。经过取样嘴流分析以及分析破乳时间对原油化验结果的影响,得出结论:原油取样口1/2处的液体更均匀,更能代表流体,确保了化验含水的真实准确性。通过地质和采油技术的措施,可消除乳化形成的因素,从根本上提高化验含水准确率。The accuracy of crude oil water content in the Hade oil and gas production area of Tarim Oilfield decreased from 92%to 75%in January and February 2022.Without changing the type of reservoir,there will be no significant fluctuations in the water content of crude oil.After analyzing the flow of the sampling nozzle,and analyzing the influence of demulsification time on the results of crude oil analysis,it is concluded that the liquid at 1/2 of the crude oil sampling port is more uniform and can better represent the fluid,ensuring the true accuracy of water content analysis.By implementing geological and oil extraction techniques,the factors causing emulsion formation can be eliminated,fundamentally improving the accuracy of laboratory testing.
