摘　　要：为满足油田示踪样品量大、需快速分析的要求,建立简单的CaCO_3样品制备方法,利用加速器质谱(AMS)测量^(14)C标记的油田示踪样品。实验中将两口采油井中的示踪样品平均分成两份,分别用于碳酸盐提取制备法与尿素载体提取法。AMS测量结果显示,1#碳酸盐系列样品中,示踪剂^(14)C的含量略高于本底,升高趋势不明显,2#碳酸盐系列样品中可能有示踪剂^(14)C的贡献,但与~3H示踪结果不符;尿素载体法提取的两个系列样品中均无明显示踪剂采出。对比^(14)C示踪与~3H示踪结果,表明^(14)C-AMS技术应用于油田示踪可以显著降低示踪剂的使用剂量。The use of ^14C as a tracer for oil field tracer has important value.Applying accelerator mass spectrometry to measure ^14C-labeled samples obtained from the oil field tracer was presented.In order to meet the requirements of large sample size and rapid analysis,a simple sample preparation process for CaCO3 had been established.The tracer samples used in the experiments came from two production wells.For each sample,it was divided evenly into two parts,one for carbonate extraction and another for urea carrier extraction.The AMS measurement results showed that the content of tracer ^14C was slightly higher than the background value in the 1# carbonate series,and the trend was not obvious.There might be tracer ^14C in the 2# carbonate series,but it did not match the ^3H tracer results.The analysis indicated that the carbonate series might be contaminated during sample preparation.Compared with ^3H,the AMS measurement results of ^14C indicate that the tracer dose requested can be significantly reduce.
