GTZ活性水增注技术在张店油田的应用

Application of GTZ Active Water in Zhangdian Oilfield

张店油田进入注水开发以来,由于储层存在着严重的水敏、乳化液堵等伤害,致使油井转注较为困难。针对张店油田注水中存在的问题,研究开发了GTZ活性水,并在南38井及南48井进行了现场增注试验,结果表明,该技术实施后,日注水量由措施前的9 m3/d上升到措施后的68 m3/d,解堵增注效果十分显著。

Due to serious sensitivity to water and plugging by emulsification liquid, it was difficult to convert oil well to water injection well since water flood recovery in Zhangdian Oilfield. GTZ active water was developed to overcome these problems and applied to the mineral field at Nan 38 and Nan 48. The result showed that it was very efficient in amplifying water injection. The amount of water injection was raised from 9 m3 /d to 68 m3/d.
