摘　　要：针对高温超深油藏固井质量不合格等问题,研究开发出一种纳米固井封窜新材料。该材料与水泥类固井材料相比,颗粒微细均匀,流变性能好,可泵时间根据具体井况调整,具有析水少,体积不收缩,强度高,可解堵,耐高温、耐高压和耐高盐的特点。室内实验和现场应用表明,纳米材料表面活性高,表面缺陷多,具有很高的化学活性,可显著改善普通材料的物理力学性能,在管外封窜方面有广阔的应用前景。A new nanometer material for sealing cement channeling has been developed to cope with unqualified cement job in high temperature ultra-deep reservoirs.Compared with well cementation material of concrete type,this material has tiny even particles and good rheological behavior,the pumping time is adjustable according to specific well conditions,showing characteristics of little bleeding,no volume shrinkage,high strength,deplugging,high temperature resistant,high pressure endurable and high salinity resistant.Laboratory experiment and field application indicate that the nanometer materials has high surfactivity,defective molecular bond and very high chemical activity,can remarkably improve the physical and mechanic performance,and has extensive and promising application prospects in sealing channeling outside casing.
