| 摘 要： | 针对尕斯油田储层多而薄，非均质性严重，岩性以细砂岩为主，各储层都存在不同程度的水敏、酸敏、速敏和盐敏等油藏特征，并为了消除储层突出的层间和层内矛盾，更好地改造油层，使尕斯油田单井产量和水井的配注量尽早达到设计要求，通过室内酸液确定试验、酸液主要添加剂选取试验、酸化暂堵剂研制试验、低伤害多效酸液添加剂 Ｌ Ｓ Ｔ系列试验等筛选出适合该油田暂堵选层的酸化配方。现场试验表明，暂堵选层酸化取得了明显的效果，既暂堵了目的层，解放了不产液层和不吸水层，又较好地消除了地层伤害，尤其对水井结垢而引起的堵塞效果极佳。

| Abstract: | The reservoir of Gasi oilfield is composed of fine sandstone beds,and the anisotropism is very serious.The different reservoir degree water sensitivity,acid, velocity and salt sensitivity. In order to improve the reservoir,through a series of experiments,the formulations for selected beds is found.The application in the oilfield shows that the acidization and temporary plug formulation is useful and the experiment has acquired good results |
