摘　　要：目前原油在线动态含水测量中 ,同位素伽马射线测量作为一项逐渐成熟的技术 ,不仅在理论模型上日趋完善 ,而且在配套技术支持上更加完美。它具有良好的稳定性、安全性 ,且量程宽、精度高 ,抗干扰能力强 ,操作简单。文章通过建立伽马射线油、气、水三相模型 ,确定了油、气、水混合液的含水率 ,并对该技术的现场应用进行了阐述。Nowadays,in measuring water cut of on-line crude oil,as a match technology,isotope γ -radioactivity measurement is not only trend to perfection in theoretical model but also more perfect in corollary suppuration. It has excellent stability,high accuracy and wide measurement scope. The water cut of crude oil is determined by establishing three phases model of oil,gas and water. practices in spot are described in the paper.
