摘　　要：介绍了暂堵酸化工艺的选井原则,给出了酸液及暂堵剂用量的计算公式。对所筛选出的暂堵剂进行了岩心评价试验,对暂堵剂的溶解性及暂堵强度进行了测定。现场实施暂堵酸化施工5井次,工艺成功率100%,暂堵有效率87.3%。The principle for well selection is introduced for using the technique of temporary plugging and acidization, the equation for the dosage of acid fluid and temporary plugging agent is given. A core evaluating test is conducted on the selected plugging agent, and its dissolution and temporary plugging intensity are detected. Field operations are made on 5 wells with success rate of 100%, the plugging efficiency is 87. 3%.
