【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。更多还原

【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) to enter the zone in certain temperature condition, decreasing the acid loss or filtration, slacking the reaction-rate of acid to rocks, aiming to deep acidization to improve the target zone.更多还原
