Abstract

This study used core and thin section analysis to investigate the time of soaking and factors that affect the mechanisms presented in the low salinity water (LSW) process. Applying a new injection plan, waterflood tests were conducted to enhance oil recovery (EOR) using the effects of soaking time. Additionally, monitoring of pressure data and scanning electron microscopy (SEM) analysis during the test were examined to investigate the fine movement. The results show that the mechanisms related to it are completely time-dependent. Changes in wettability can be defined in the concept of ion exchange. The fine migration mechanism was observed in the LSW process, but its direct impact on the EOR is under discussion.

砂岩储层浸泡时间对低矿化度注水的影响:润湿性、扫描电镜、相对渗透率和水驱研究

采用岩心分析和薄片分析方法，研究了低盐度水浸泡时间和影响低盐度水浸泡机理的因素。采用新的注水方案，利用浸泡时间的影响，进行了提高采收率的水驱试验。此外，还对测试过程中的压力数据监测和扫描电子显微镜(SEM)分析进行了检查，以研究精细运动。结果表明，与之相关的机制是完全时变的。润湿性的变化可以用离子交换的概念来定义。在LSW过程中观察到了细微的运移机制，但其对提高采收率的直接影响尚在讨论中。

期刊介绍： Egyptian Journal of Petroleum is addressed to the fields of crude oil, natural gas, energy and related subjects. Its objective is to serve as a forum for research and development covering the following areas: • Sedimentation and petroleum exploration. • Production. • Analysis and testing. • Chemistry and technology of petroleum and natural gas. • Refining and processing. • Catalysis. • Applications and petrochemicals. It also publishes original research papers and reviews in areas relating to synthetic fuels and lubricants - pollution - corrosion - alternate sources of energy - gasification, liquefaction and geology of coal - tar sands and oil shale - biomass as a source of renewable energy. To meet with these requirements the Egyptian Journal of Petroleum welcomes manuscripts and review papers reporting on the state-of-the-art in the aforementioned topics. The Egyptian Journal of Petroleum is also willing to publish the proceedings of petroleum and energy related conferences in a single volume form.
