氚水示踪技术在大庆油田的应用

AN APPLICATION OF TRITIUM WATER TRACER IN DAQING OILFIELD

大庆油田现场使用结果表明,氚水是一种性能良好的示踪剂,具有易于检测,采出浓度分布曲线波动范围小,曲线变化趋势明显,峰值易于判断等特点,在氚水的注入和采出过程中做好防护,不会对环境产生污染和危害人体,在此同时,应用氚水还可比化学示踪剂获得显著的经济效益,因此在油田上广泛应用氚水示踪技术是可行的。

<ABSTRACT> Result of field application in Daqing oilfield shows ihat tritium water is a. performance satisfactory tracer.It is characterized by easy detecting, fluctuation scale of distribution curve of withdrawal concentration is small, changing trend of curve is clear and peak value is easyto be determined. During tritium water injection and withdrawal, protection work should be done so envir onment pollution and personal damage could not occur. Besides, using tritium water can get better economic benefits than chemical, wide-ranging application of tritium water tracer is faesible in oilfields.
