摘　　要：随着油田对注水精细描述需求的增加,井间示踪监测技术已经从单井、单层位测试向多井、多层位、多轮次、整体区块应用方向发展。其中,含氟示踪剂由于其种类较多、示踪性能良好,已成为油田应用的主要产品之一。但对于同时存在多种含氟示踪剂的水样,目前的分析方法难以满足快速、准确的测试需求。针对这一问题,本文采用三重四级杆液质联用仪,Agilent Poroshell C18色谱柱(3.0 mm×50 mm,2.7μm),乙腈-水作为流动相,梯度洗脱,质谱采用电喷雾ESI负离子模式,研究了10种含氟示踪剂在油田产出水中的液质联用检测方法。该方法在实际油田水样品测试中,在浓度10μg/L^1000μg/L范围内线性关系良好,相关系数R2均>0.999,回收率在96.9%~102.7%,较好的满足了油田示踪监测的要求。With the increasing demand for detailed description of water injection in oilfields,the inter-well tracer monitoring technology has developed from single well and single-layer testing to multi-well,multi-layer,multi-round and integral block application.Among them,fluorine-containing tracer has become one of the main products in oilfield application because of its variety and good tracing performance.However,for water samples containing various fluorine tracers at the same time,the current analytical methods cannot meet the needs of rapid and accurate testing.In order to solve this problem,the LC/MS methods of 10 kinds of fluorine-containing tracers in oilfield produced water were studied in this paper.Triple quadrupole LC/MS was used.Agilent Poroshell C18 column(3.0 mm×50 mm,2.7μm)as column,acetonitrile-water as mobile phase,gradient elution,and mass spectrometry using electrospray ESI negative ion mode.This method has a good linear relationship in the range of concentration 10μg/L^1000μg/L in the actual oilfield water sample test.The correlation coefficient R2>0.999,and the recovery rate is between 96.9%and 102.7%.It satisfies the requirements of oilfield tracer monitoring.
