| 摘 要： | 南堡A凝析气井具有埋藏深、温度高、井段长，渗透率低、岩性复杂等特点。针对该井的缓速、缓蚀，凝析气藏防止水锁和反凝析、长井段布酸等关键技术难点，从酸液体系和工艺技术上给出了相应对策；利用多氢酸反应速度慢、溶解能力强，具有良好的防垢性能和分散性能，可以有效控制二次沉淀等优点，采用凝析气藏多氢酸酸化技术，对南堡A凝析气井进行酸化，取得较好效果，对南堡油田其他低效凝析气井增产改造工作的实施提供了借鉴。

| Abstract: | Nanpu A condensate-gas reservoir has features of being buried depth, high temperature, long drilled section, low permeability and complex lithology. According to the main technical problems of retarding and corrosion inhibitor of HP-HT well, condensate-gas reservoir preventing water lock, inverse condensate and long section to describe acid, corresponding strategy is given by acid system and technology. By use of advantages of low speed of reaction, high capacity of resolution and good performance of scale ... |
