为了降低压裂液在管柱中的摩阻，从而达到有效压裂的目的，研制出了由阳离子与非离子单体在一定条件下聚合而成的水基降阻剂ＪＨＪ，并对其进行了性能评价。结果表明，ＪＨＪ具有好的水溶性、酸溶性、热稳定性、降阻性和适应温度范围广（在３０～９０℃条件下不生成絮状物沉淀）等特点；用它配成的降阻酸还具有一定的缓速性能。该产品的研制对提高油田的开采速度和采收率具有很大意义。
In order to reduce the friction of the fracturing fluid in the column and achieve the purpose of effective fracturing, a water-based reducing agent JHJ polymerized from cationic and non-ionic monomers under certain conditions was developed and carried out Performance evaluation. The results showed that JHJ has the characteristics of good water solubility, acid solubility, thermal stability, resistance reduction and wide temperature range (no flocculent precipitation at 30 ~ 90 ℃) Acid also has a certain retarding properties. The development of the product is of great significance to improve the recovery rate and recovery rate of the oil field.
