深部缓速酸化技术室内评价及应用效果分析

Laboratory Evaluation and Application Results Analysis of Deep Slowly Acidizing Technique

通过对深部缓速酸化技术的室内实验评价,充分验证了深部缓速酸化技术的各种性能指标,并通过岩心流动模拟实验对比了深部缓速酸化技术与常规土酸酸化技术的技术优势,以及在葡萄花油田现场应用的效果,为今后油田注水井酸化解堵提供了一条新途径。

Based on laboratory evaluation of deep slowly acidizing technique, various performance indexes of this technique are fully validated. According to flowing simulation tests of cores, the application results in Putaohua oilfield, as well as technical predominance of seep slowly acidizing technique comparing to conventional acidizing technique, are analyzed. This technique may provide a new method for acidizing and deplugging of injectors.
