酸液体系的研究现状分析和现场应用

Analysis on Current Status of the Research of Acid Fluid System and Field Application

酸化解堵与压裂改造相比,它具有施工相对简单和成本相对较低等特点,所以酸化解堵是一项各油田广泛使用的油气田增产技术。酸化解堵技术已有将近100历史,现已研制出具有不同特点的酸液体系,如乳化酸、泡沫酸、固体酸、多氢酸等,基本能满足复杂地质条件对酸液的要求。

Compared with Acidizing Plugging Removal and Fracturing,Acidizing Plugging Removal had the characteristics of relative simply working and relative lower cost,so Acidizing Plugging Removal was a kind of extensive using stimulation technique in all oilfield.Acidizing technology already had about 100 history,develops acid fluid system with distinct characteristics,for example,emulsified acid,foamed acid,acid powder,multi-hydrogen acid and so on,fundamentally satisfies acid fluid requiring in complicated geologic setting.
