摘要
TH变粘酸在低渗透碳酸盐储层酸压施工中具有重要的意义。本文采用实验方法,把TH变粘酸的各种性能与传统的胶凝酸酸压作了对比,提出了TH变粘酸的最佳施工方案。现场试验表明,采用变粘酸体系施工,裂缝长度较胶凝酸体系施工增加一倍,滤失系数及酸液滤失量减少约50%,增产效果在胶凝酸基础上提高了2.5倍。与常规胶凝酸相比,研制的TH变粘酸表现出明显的残酸增粘性能和较高的粘度。
As variable viscidity acid plays a very important role in the process of acid fracturing on low osmotic carbonate reservoir bed, this thesis gives a comparison between variable viscidity acid and traditional gel acid in acid fracturing. It developed a way of how to optimize the function of variable viscidity acid and foresee its foreground on the base of experimentation.
