| 摘 要： | 根据储层特征、储层的敏感性、前期地层损害及重复酸化等因素,通过大量室内试验,研究出了适合塔里木轮南油田二井区的重复酸化增注工作液,即有机缓速酸体系。该体系既满足了深度酸化和重复酸化工作液要求,又能降低地层二次损害。通过在LN2-4-6和LN2-2-7井现场应用,取得了良好的酸化效果,表明该酸化工作液与该井区储层的适应性好。

| Abstract: | According to the property of formation, formation-sensitive, formation fore-damage and reacidizing factors and so on,the reacidizing work fluid,that is an o-riginic relieving acid system, adapted to Lunnan oilfield No. 2 well area in Tarim is researched by a large amount of testing in the room. This system satisfies for the deep acidizing and reacidizing and reduces the second formation damage. The system had been applied on LN2-4-6 and LN2-2-7 well with good acidizing result. It shows that the acidizing work fluid adapts better to the reservoir of this well area. |
