录井岩样荧光面积定量化分析软件开发

Development of fluorescence area quantitative analysis software for mud logging rock samples

针对石油钻探现场采用传统的人眼识别判断岩样荧光显示存在结果不确定性的问题,基于成熟的光学成像技术,开发了岩样荧光面积定量化分析识别软件。该软件通过一系列运算提取出岩样数字图像的颜色信息,并最终得到定量化的岩样颜色统计数据,利用岩样白光图像和荧光图像的数据对比,经数字图像处理技术分析,获得岩样的荧光像素数据,最终实现了岩样荧光面积的定量化分析。该软件有效地克服了随钻勘探油气显示识别中人为不确定因素的干扰,加速了录井技术智能化进程,对录井技术的发展和数据质量的提高具有积极意义。

Be directed against the uncertainty in the results of traditional human visual cognition and judgment of rock sample fluorescent display in petroleum drilling site,a software for quantitative analysis and identification of rock sample fluorescence area was developed based on proven optical imaging technique.The software extracts the color information of digital image of rock samples through a series of calculations,and finally obtains quantified statistical data of rock sample colors.Using the data correlation between the white light images and the fluorescence images of the rock samples,and through the analysis of the digital image processing technology,the fluorescence pixels of the rock samples are got,and the quantitative analyses of the rock sample fluorescence area are realized at last.The application of this software effectively overcomes the interference of human uncertain factors in the identification of the show of gas and oil in exploration while drilling,accelerates the intelligent progress of mud logging technology,and is valuable to the development of mud technology and the improvement of data quality.
