摘　　要：研究了VES(ViscoelasticSurfactant,粘弹性表面活性剂)流体的基本性能,包括VES增稠能力、反离子加量对VES胶束的影响、盐水对VES胶束溶液性能影响、VES胶束溶液的抗剪切性能和破胶性能。VES在青海油田清洁酸化和清洁压裂中得到成功应用,为该油田特别是低压低渗水敏油田探索了一种新的增产技术,具有广阔的应用前景。The basic behavior of viscoelastic fluid of long-chain fatty-acid derivant hyamine surfactant is studied,which includes the thickening ability of viscoelastic surfactant (VES),the effect of anti-ionic dosage on VES micelles,the effect of brine on the property of VES solution,and the shear resistance and break character of VES micelle solution.VES is successfully used in clean acidizing and clean fracturing in Qinghai Oilfield,by which a stimulation technique is provided for the oilfield,especially for extra-low pressure and water sensitive oilfields,it has wide application prospects.
