以低分子醇类配制的醇基压裂液，应用于低渗透致密气藏可促进返排，有效解除水锁，增加气井产量。分析了低分子醇类对羟丙基胍胶分子(HPG)溶胀及交联的影响机理，研制了专用增溶剂和交联促进剂，实现了 HPG 配制醇基压裂液，醇含量可达20%(w)，性能优良。该体系在 JN 气田致密砂岩储层成功应用，效果明显优于同类储层邻井。

The alcohol fracturing fluid prepared with low molecular weight alcohols can be used in low permeability tight reservoirs to promote flow back,effectively relieve water locking,and increase production of wells.The influence mechanism of alcohols to hydroxypropyl guar gum swelling and crosslinking reaction was analyzed.Special solubilizer and crosslinking promoter have been developed, the alcohol fracturing fluid (alcohols amount up to 20%)have been successfully prepared by HPG. The fluid system was applied on tight sandstone gas reservoir in JN gas field,and the effect was supe-rior to the adjacent wells of similar reservoirs.
