利用γ射线测量原油含水率和含气率的数学算法分析

The mathematical method in measuring water-rate and gas-rate of petroleum in means of γ-ray

详细分析了利用 γ射线测量原油含水率和含气率的数学算法 ,以及减小逃逸效应对系统精度的影响。该方法已被成功地用于油田生产中对油水气三相介质的自动在线计量系统。

The details about mathematics method in measuring water rate and gas rate of petroleum in means of two kinds of energy γ rays are described in this thesis. It is also included how to reduce the influence of escape effect ofγ ray on measuring precision.
