摘　　要：本文针对大庆A区块特高含水期的堵水层位未知,且薄差储层堵水难度大、卡段困难,优选了一种选择性化学堵水剂,并采用室内实验的方法,对堵水剂配方做出了室内评价,结果表明,此堵水剂配方封堵率较好且具有良好的选择性。在A区块现场施工3口井,应用效果较好。In view of the unknown water plugging level in Daqing A block and the difficulty of water plugging,a selective chemical water plugging agent formula was studied. The indoor test method was used to make a laboratory evaluation on the formula of water plugging agent. The results showed that the blocking rate of the water plugging agent was good and had good selectivity. The construction of 3 wells in A block is effective.
