摘　　要：针对陈25块地下稠油黏度高、水驱采收率低的问题,提出了改性纳米硅强化乳状液深部调驱技术。室内以廉价脂肪酸甲酯为油相,利用改性纳米硅和TX-60S乳化剂的协同作用,开发了改性纳米硅乳化剂稳定乳状液体系,并考察了不同乳化剂浓度、无机盐浓度等对乳状液体系的稳定性、耐温性、粒度分布以及流变性的影响,得出最佳乳状液配方体系。性能评价表明,改性纳米硅质量分数超过0.30%时,乳状液的黏度显著上升,且耐盐性允许NaCl的质量分数达到2.50%。According to the characteristics of Chen 25 block, high viscosity of underground heavy displacement recovery, the modified nano silicon intens indoor experiment takes cheap fatty acid methyl ester as emulsion stability system based on the synergistic effect ferent concentration size distribution and of emulsifier, inorganic rheological property are formance evaluation shows that the viscosity nano silicon is higher than O. 30% . and the ified emulsion deep flooding technology is the oil of nano salt concentration oil and low water put forward. The phase, to develop a modified nano silicon emulsifier silicon and TX -60S emulsifier. The effects of dif- on emulsion stability, system temperature, particle investigated to obtain the best emulsion formulation system. The per- of emulsion increases significantly when the concentration of modified salt resistance is within the range of 2.50%.
