摘要:改性纳米SiO_(2)渗吸驱油技术在实现超低渗油藏提高采收率方面具有优势。从结构分离压力、改变储层润湿性、降低油水界面张力和密度差异角度分析了改性纳米SiO_(2)的渗吸驱油机理,概述了纳米SiO_(2)化学改性、半化学/物理吸附改性及原位合成改性的国内外研究现状,展望了改性纳米SiO_(2)在超低渗油藏提高采收率领域的未来研究重点。
Modified nano-SiO_(2) imbibition flooding technology has advantages in realizing enhanced oil recovery in ultra-low permeability reservoirs.The imbibition flooding mechanism of modified nano-SiO_(2) is summarized and analyzed from the aspects of structural separation pressure,changing reservoir wettability,reducing oil-water interfacial tension and density difference.Global research status in chemical modification,semi-chemical/physical adsorption modification and in-situ synthesis modification of nano-SiO_(2) is summarized.The future research focus of modified nano-SiO_(2) in the field of enhanced oil recovery in ultra-low permeability reservoirs is prospected.
