| 摘要: |
| 针对长庆油田低渗、非均质严重、矿物中绿泥石含量高、酸化效果差的特点,研制了缓速性能好的IPPA酸、酸液添加剂来解决长庆油田酸化效果差的问题。结果 表明,IPPA酸液体系具备增强酸液的缓速及抑制二次沉淀功能,提高了酸化效果。现场实施缓速深部酸化8口井,成功率为90%,取得了较好的效果。 |

| Abstract: |
| In view of low permeability,severe nonhomogeneity,the high content of chlorite and the bad acid effect,the original triturates IPPA acid and additive were applicated to resolve the problem of Changqing oil field aciding effect.The results indicated that IPPA acid system could raise the aciding retardant and prevented the second deposit,and enhanced the aciding effect.Thirteen wells’deep aciding were conducted,the success rate was 90%,acquired good effect. |
