摘要
荧光显微图像技术以紫外光或蓝光作为光源,通过激发岩石中石油沥青物质后产生出可见的荧光图像,可直观观察石油沥青物质在岩石中的分布状况,为油层评价提供微观可视化信息。为进一步推广该项技术的应用,对荧光显微图像特征量化处理的18项参数进行了研究,以试油、投产资料为优选依据,建立了不同油质的油层和油水层定性判别方法,归纳总结了喇萨杏油田水淹层评价方法,并根据定量参数分别建立了油水层、水淹层评价图板,在新井中验证应用,见到较好的效果。
Technology of fluorescence microscopy images takes the ultraviolet light or blue light as the light sources,the visible fluorescence images can be produced by stimulating petroleum asphalt substances of the rock,which can be used to visually observe petroleum asphalt substance distribution in the rock and provide microscopic visualization information for reservoir evaluation.To further promote the application of this technology,the author studied 18 parameters that quantitatively processed the features of fluorescence microscopy images.Based on oil test and production data,the qualitative discriminant method was established for oil layers with various oil qualities and oil-water layers.The paper summed up the evaluation methods for the flooded layers in Labadian,Saértu and Xingshugang oilfields and the charts of oil,water and flooded layers were established according to the quantitative parameters.The application of this technology to new wells got good results.
