低渗透油藏注水井小型酸化解堵的一个成功实例

An successful example of acid pickling for an injection-well of low permeability reservoir

文章介绍了临盘采油厂低渗透油藏一口注水井的酸化解堵实例。此实例表明,用小型酸化可成功解决注水注不进的难题。此井用3m3土酸的小型酸化,注水有效期长达近6个月,目前仍然有效,且此井对应的受效油井见效明显,因此此井对类似注水井有一定借鉴意义。

This article mainly introduces an successful example of acid pickling for an injection-well of low permeability reservoir in Linpan Oilfield.It demonstrates that,acid pickling can solve the problem in water-injection.We used 3 m3 earth acid for the acid pickling of this injection-well,and had acquired a longevity of 6 months.Until now,it＇s still effective,and the corresponding oil-wells has also recovered obvious effect.Therefore,other injection-wells can refer to it.
