利用放射线测量油管中的原油密度和含水率

Measuremeant of density and water cut of oil in oil piping by radioactivity

分析了混水原油中O ,H ,C ,Be ,水 ,原油和甲烷的质量吸收系数的特点 ,选取放射源10 9Cd ,利用不同能量的伽马射线与流动的混水原油的相互作用所产生的光电效应、康普顿效应和电子对效应 ,测定混水原油的平均密度和含水率 .结果表明 ,测量准确 ,且快速、简便 。

This paper analyses characteristics of mass absorpt ion coefficient of O, H, C, Be, H 2O, oil and CH 4 in the oil, and selects rad ioactive source 109 Cd, take photoelectric effect and Compton's effect and e lectron effect of gamma ray of different energy and running oil. We can accurate ly measure the density and water cut of running oil in the oil piping using thei r relation. The method of oil density and water cut measuring can be used in oil -logging, oil-storing and oil-transporting.
