    Abstract: A method for stimulating thick or multilayered heterogeneous or homogeneous formations in a single trip without packers involves perforating with tubing conveyed perforation, then injecting a self-diverting acid, then moving the tubing string and perforating at a new location, and then injecting additional self-diverting acid. The sequence may be repeated. The acid is preferably a viscoelastic diverting acid. The self-diverting acid may be alternated with conventional treatment fluid. The job is designed to treat the least permeable zone(s) first and maximizes acid efficiency.

    Abstract translation: 在没有封隔器的情况下在单次行程中刺激厚层或多层异质或均匀地层的方法包括用输送穿孔的管道穿孔,然后注入自转向酸,然后移动管柱并在新位置穿孔, 转移酸 可以重复该顺序。 酸优选为粘弹性转移酸。 自转向酸可以与常规处理液交替。 该工作旨在首先处理最不透水的区域,并最大限度地提高酸的效率。
