文章介绍了一种新型Ｘ射线荧光测井仪的硬件与软件。该测井仪井下探管外径４２ｍｍ，以充稀有气体的正比计数器为探测器，以８０９８微机芯片管理的２５６道脉冲幅度分析系统，可以一次下井同时测定两种或多种元素含量，实现了在地面计算机控制下的数字传输、数字收录和数据处理。开发的软件具有原始数据采集、能谱分析、含量与储量计算等功能。野外锶矿测井试验表明：Ｘ射线荧光测井仪可在井场实时提供锶、钡两种元素的品位，其耗费的时间周期还不到传统方法的１／３０
The paper introduces the hardware and software of a new type of X-ray fluorescence tool. The downhole probe underground diameter 42mm, with rare gas proportional counter as the detector to 8098 microprocessor-controlled 256-pulse amplitude analysis system, you can go down at the same time measuring two or more elements, to achieve Digital transmission, digital recording and data processing under the control of the ground computer. Developed software with the original data acquisition, energy spectrum analysis, content and reserve calculation functions. Field strontium ore logging test shows that X-ray fluorescence logging instrument can provide strontium and barium grade in real time in the wellsite, which consumes less than 1/30 of the time of the traditional method
