摘要
分析了酸压过程中酸液的滤失机理,从酸液体系和酸压工艺两个方面提出了各种常用的控制酸液滤失的方法; 酸液滤失对酸压设计结果影响较大,酸液滤失模型是酸压设计中的重要组成部分,但准确的计算酸液滤失的模型仍在不断的完善之中,通常仍将一般的压裂液滤失模型用于酸压设计,介绍了国内外学者关于酸液滤失模型的研究。
The leak-off mechanism in the course of acid fracturing is ana lyzed, the various common methods controlling acidizing fluid leak-off are put forward from such two aspects as acidizing fluid system and acid fracturing technology, acidizing fluid leak-off has considerable influence on the results of acid fracturing design, the acidizing fluid filtration model is still an important composite part in acid fracturing design, but the model of ac curately calculating aciding fluid leadoff is still in the midst of uninterupted perfection, usually the ordinary model of fracturing fluid is used in the acid fracturing design, the domestic and overseas scholars＇ study about the model of calculating aciding fluid leak-off is introduced.
