摘要:

在碳酸盐岩酸压处理中，温控交联酸BN-76与传统的碳酸盐岩酸压（化）技术相比具有更多优点，具有更加广泛的应用前景。BN-76温控交联酸在一定（地层）温度条件下，通过交联剂产生的化学键作用使酸液形成冻胶状进入地层，可降低酸液滤失，延缓酸岩反应速率，达到深部酸化改造地层的目的。

Abstract:

In the process of Acid-Frac of carbonate, Temperature-controlled cross-linked acid(BN-76) has its great superiorities over traditional Acid-Frac ( acidization) techniques. It will premote the acid to be gel through chemical bond formed by cross-linker(s)
