应用荧光显微技术判别吐哈盆地储层含油水性

通过在荧光镜下的油水特征实验，分别得出油、油包水、水包油、含油水、水的荧光特征，然后对吐哈盆地单井储层的油层、水层荧光特征反复实验，并与试油结果对比，归纳总结出了油层、水层及油水界面的识别标志。油层特征主要为荧光发光较好且均匀、大面积油包水；水层特征主要为荧光发光不均匀，可动水普遍，并出现水包油现象；油水界面特征主要为荧光从均匀发光过渡到不均匀发光，孔隙由可动油充填过渡到由可动水充填。提出了吐哈盆地储层含油规律性，从而为探井试油、油层划分提供了准确可靠的依据。

Identification of oil-water bearing reservoirs with fluorescent microscopic technology in Tuha Basin

By the oil-water characteristics test under the fluorescent microscope,the fluorescent characteristics of oil, water-in-oil, oil-in-water, oil-bearing water and water are obtained respectively. Then by experimenting repeatedly upon the fluorescent characteristics of oil layers and water layers for reservoirs of a single well in the Tuha Basin and compared those with the results of testing oil, the identifying markers of oil layer, water layer and oil-water interface are summaried as follows. The oil layer is principally characterized by better and uniform fluorescence as well as extensive water-in-oil. The water layer is mainly characterized by non-uniform fluorescence and widespread mobile water with the appearance of oil-in-water. The oil-water interface is primarily characterized by fluorescence transition from uniform to non-uniform and pore filling transition from mobile oil to mobile water. And the occurrence of oil bearing reservoirs in this region is revealed. Thus, it can provide evidence for testing oil of exploratory well and the division of oil layers .
