射线型原油含气、含水率自动监测仪原理及应用

Principle and application of the ray automatic monitor of gas and water contents in crude oil

射线型原油含气、含水率自动计量系统是基于油、气、水三种不同介质对一定能量的γ射线的吸收不同,通过检测γ射线穿过油、气、水的混合物后的透射计数,理论计算,实现对原油含气、含水率的在线分析。工作方式为全自动在线连续测量,该计量监测系统设计新颖、测量准确、安全可靠、运行稳定、使用寿命长、便于操作,特别是修正了由于原油中含气对含水率测量的影响。

Based on differental absorption of oil,gas and water mediums on γ ray,by means of measuring transmission counts of γ ray through oil,gas and water mixtures,and theorically calculating,the ray automatic detector of gas and water contents in crude oil can automatically and continuously measure gas and water contents in crude oil online. The monitor is novel in design,accurate in measurment,stability in running,and safe and reliable.
