摘　　要：针对涩北气田储层特性,对YH-01压井液暂堵剂压井液进行了室内评价和现场应用。结果表明:该压井液暂堵成功率高、复产率高、费用低及现场配液方便,现场累计试验52井次,井平均压力系数0.66,试验后井均漏速降低90%以上,气井复产率可达85%。According to the reservoir characteristics of Sebei gas field,YH-01 kill fluid(temporary plugging agent kill fluid)was evaluated in laboratory and applied in field.The results show that the well killing fluid has high success rate of plugging,high recovery rate,low cost and convenient on-site liquid preparation.The field test has been conducted for 52 wells,and the average pressure coefficient of the well is 0.66.After the test,the average leakage rate of the well is reduced by more than 90%,and the recovery rate of the gas well can reach 85%.
