双能γ射线透射法测原油含水含气的分析与计量系统

An analysis and measurement system of percentage of water and gas content in petroleum by radiation isotope

介绍了利用射线辐射衰减方法实现的原油含水率、含气率在线分析与计量系统。它采用双能 γ放射源和闪烁探测器 ,用计算机获取探测到的γ射线穿过原油的透射计数 ,并由此计算出油、水、气的体积百分数 ,除此之外 ,该系统还能监测温度、压力和流量 ,从而得出产液量、产油量、产水量和产气量。

An on line analysis and measurement system of percentage of water and gas contents in petroleum by using radiation isotope is described. A radiation source that emits two different γ rays energies and a scintillation detector are used in the system . The computer reads the transmission counts of γ rays that pass through petroleum for analyzing oil, water and gas contents. The system also measures the temperature, pressure and flow, so the amounts of liquid, oil, gas and water can be calculated conveniently.
