OFA系列石油荧光分析仪

A new petroleum fluorescence analyser.

OFA系列石油荧光分析仪由中国石油勘探开发研究院与上海三科仪器有限公司合作研制开发 ,既能检测轻质油、凝析油、煤成油 ,反映各种原油样品的二维荧光全貌 ,又能实现较准确定量和排除钻井液添加剂荧光干扰 ,使用微机控制 ,数据处理自动化程度很高 ,是全新的现场用系列石油荧光分析仪。该类仪器检测石油的灵敏度为 0 .1mg/L ,重复性误差小于 3 % ,在石油含量小于 40mg/L时 ,R2 可达 0 .99以上 ,可以消除比测定目标石油浓度高 10倍以上的钻井液添加剂的荧光干扰 ,仪器的总体设计达到了国际先进水平。列举了用该类仪器在实验室和钻井现场测得的大量荧光数据和图谱 ,指出该仪器各项性能指标均优于传统的和国际上现有的荧光录井仪器与方法。图 5表 2参

This paper introduces a new series of Oil Fluoroanalyser (OFA) controlled by c omputer. It can not only test various kinds of crude oil, reflecting their 2 D fluorescence spectrum, but also quantify exactly and eliminate various fluoresce nt interference coming from drilling mud additives. Their sensitivity of measuri ng oil is 0.1mg/L, repeatable accuracy is more than 97% and R 2 is more than 0. 99 when oil content in solution is less than 40mg/L. Here is cited a large numb er of fluorescence data and spectra getting from the labs and the drilling field s where the OFA was used, compared them with the data obtained by the other meth ods and instruments, and enumerated its advantages.
