应用荧光显微技术判别吐哈盆地储层含油水性
JOURNAL OF EARTH SCIENCES AND ENVIRONMENT(2005)
Abstract
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.
