摘要

通过将疏水的纳米颗粒吸附在岩心微通道壁面, 可以形成具有类荷叶表面的双重微结构表面, 从而在注水开发的过程中在岩心微通道壁面产生水流滑移, 达到降低注水压力、增加注水量的目的. 研究纳米颗粒吸附岩心切片表面的强疏水特征对纳米颗粒吸附法减阻技术具有重要的意义. 本文简要叙述了荷叶、蚊子腿以及水黾腿的超疏水特征; 介绍了制备具有亚微米、纳米双重微结构的强疏水表面的纳米颗粒吸附法; 给出了规则排列时纳米颗粒吸附岩心切片表面的强疏水特征的物理机制, 根据真实的纳米颗粒吸附岩心切片, 给出了接触角的范围, 计算结果与实验数据一致. 岩心流动实验结果表明, 经纳米颗粒分散液处理后, 岩心的平均水相渗透率提高94%.

Abstract: A compact hydrophobic nanoparticle (HNP) adsorption layer, which has miro- and nano-dual structural properties like lotus leaf, can be built by adsorbing HNP on core surfaces. A slip velocity on the surface can be produced with the purpose of reducing the water resistance and increasing water injection rate. The results are of significance for the study of HNP drag reduction technology. In this paper we give a briefing of the super hydrophobic properties of the lotus leaf, mosquito legs, and striders leg. The strong hydrophobic surface preparation method with HNP adsorption layer is presented, and physical mechanism of strong hydrophobic surfaces with regular arrangement of HNPs is given. According to the real HNP adsorption core samples, the contact angle range is given, the calculation results accord well with experimental data. Core displacement experimental results show that the average drag reduction rate can be up to 94%.
