摘要
针对大庆头台油田原油含蜡量高、凝固点高、粘度大等特点，探讨了所研究的ＣＹ－Ⅳ油溶性清防蜡剂的性能，经５口井现场试验及１８０多口井的应用，得出了用此化学清防蜡剂可使低含水。低产油井避免热洗的结论。
According to the characteristics of high wax content,high pour point,and high viscosity of crude oil in Toutai oilfield, a oil soluble paraffin removal and control solvent CY-Ⅳ has been develope,results from field test in 5 wells and applications in l80 wells show that it can make wells with low production and water-cut avoiding thermal flushing for paraffin removal.
