Abstract

Wettability is a critical interface property for two-phase flow and reactive transport process in porous media. Wettability alteration is considered as the dominated mechanism for enhanced oil recovery during low salinity waterflooding. The conventional characterization of wettability by contact angle at a single substrate and Amott method at core are limited. In this minireview, we introduce recent improvements in characterization of the electrochemical properties of an interfacial layer formed at the mineral-water interface, and review the application of surface potential (i.e., zeta potential) as an invasive and reliable technique to characterise the wetting behaviour of sample core across different geochemistry conditions. In order to resolve the puzzle of the wettability alteration in an oil-brine-rock system, experimental studies combined with numerical simulations across multiscale and variable geochemistry conditions are required for the future investigation.

简要回顾了多孔介质中电学性质与润湿行为之间的关系

润湿性是多孔介质中两相流动和反应输运过程的关键界面性质。润湿性蚀变被认为是低矿化度水驱提高采收率的主要机理。传统的表征润湿性的方法是在单一基材上的接触角和在核心处的Amott方法是有限的。在这篇小型综述中，我们介绍了最近在表征矿物质-水界面形成的界面层的电化学特性方面的改进，并回顾了表面电位(即zeta电位)作为一种侵入性和可靠的技术在不同地球化学条件下表征样品岩心润湿行为的应用。为了解决油-盐-岩体系润湿性变化的难题，需要在多尺度和不同地球化学条件下进行实验研究和数值模拟相结合的研究。引用自:李，生，侯，生。多孔介质中电学性质与润湿行为的关系综述。毛细管学，2019,2(3):53-56,doi: 10.26804/capi.2019.03.02。
