摘要: 近年来,泡沫流体在三次采油中越来越受到学者重视,在提高三次采油采收率机理研究方面,计算机层析(CT)有着自身技术上的优势。本文利用ACTIS微焦点X-rayCT技术对三次采油中泡沫驱油岩心进行研究与分析,直观地描述岩心中泡沫的特征与分布规律。采用可视化新方法研究得出泡沫驱油中的流体饱和度分布,揭示泡沫驱油特征机理。研究结果对于指导矿场试验具有重要意义。

Abstract: Recently, the foam fluid is cared about by more and more academics in Enhance Oil Recovery (EOR). The CT technology has its own advantages in EOR mechanism. By researches and analyses foam flooding with BIR ACTIS (CT), this paper gives a visual description to the foam feature and distribution in media, uses a new visual method to study the oil saturation and reveals the mechanism of the foam flooding.Resultsof the study have significance for guiding the field application.
