酸压施工的成功与否主要取决于酸液有效作用距离和酸蚀裂缝导流能力。
Whether the treatment successes or not mainly depends on the acid etched fracture conductivity and effective distance of acid-rock reaction.
碳酸盐岩储层通过酸压改造，提高裂缝长度和酸液有效作用距离，是提高酸压措施建产率的关键。
Increase the effective distance between fracture length and acid by acid-fracturing treatment is a key to improve acid-fracturing producing rate for carbonate reservoir.
首先，高温下常规土酸与地层矿物反应速度极快，酸液有效作用距离短，活性酸不能到达地层深部；
First, the speed of the reaction between mud acid and rock is very fast, the effective distance of acid is short, active acid can not reach deep formation.
