摘要
对放射性同位素源X荧光测井技术的井液效应、并壁不平度效应和基体效应分别提出了实用的校正技术。野外锶矿X荧光测井试验表明:X荧光测井确定的锶矿层厚度和平均品位传统的岩芯化学分析结果相比较,基相对误差<10%,符合锶矿储量计算要求;X荧光测井可在井场实时提供测井结果,而耗时却短得多。
The basic principle of radioisotope X-ray fluorescence logging technique has been described.Some practical methods for correcting unevenness effects,drilling fluid effects and matrix effects are presented.A test on strontium deposit showed that relative errors between thicknesses and average ore grades of the strontium seams determined by X-ray fluorescence logging and by traditional core-chemical analysis are less than 10%,which can meet the requirments of reserve calculation standard.It is also shown that the consuming time for X-ray fluorescence logging is much less than that for traditional methods.
