| 摘 要： | 用SNP1-1、SNP2-2和SNP2-4三种疏水纳米材料分别与柴油配制成3种油基纳米液,用SNP2-2分别与ND3和ND4配制成2种水基纳米液,通过岩心流动实验测试了这5种纳米液的减阻效果.实验结果显示,3种油基纳米液使岩心水相渗透率提高了42%、49%和24%,2种水基纳米液分别使岩心水相渗透率提高了17.5%和75%,5种纳米液都具有减阻效果,但不同纳米液的效果差异明显,这说明增注液不具有唯一性,但纳米粒径、修饰剂和分散剂对减阻效果有明显的影响.测试了SNP2-2油基纳米液处理岩心的耐冲刷能力,岩心经180倍孔隙体积(PV)水的驱替,仍具有一定的效果,说明纳米边界层流道壁面有较强的吸附能力.现场采用SNP2-2和ND4配制的纳米液进行了三口井的增注试验,注水压力最大降幅12.5MPa.研究结果与实验前的设想相符,较好地说明了纳米减阻机理.

| Abstract: | Three oil-based nanomaterial fluids(NFs) were made up of three various hydrophobic nanomaterials SNP1-1,SNP2-2,SNP2-4(SNP1-1 and SNP2-2 are same size of nanomaterials modified by two different modifiers.SNP2-2,SNP2-4 are different sizes of nanomaterials modified by same modifier) respectively and diesel oil,and two water-based nanomaterial fluids(NFs) were made up of SNP2-2 and two water-based dispersions ND3,ND4 respectively,the drag reduction effects of these five NFs were tested in core microchannel by c... |
