随着水平井规模化应用，水平井增产改造措施发挥着越来越重要的作用。为保证井中多段储层充分改造，发挥水平段每个油气段的产能，使改造具有针对性、选择性，进行水平井选择性酸化工艺开发尤显重要。介绍了一种在水平井用连续油管拖动选择性酸化工艺方法，对作业关键参数进行了实验分析与理论研究，确立施工参数并在DH20-4H井成功进行了现场实施。

With large-scale application of horizontal wells, the stimulation and reform of horizontal wells has been playing a more and more important role in increasing oil/gas production. In order to ensure fully fracturing of multi-stage reservoir in well, make play the capacity of each stage in horizontal section and make the reconstruction more pertinent and more selective, the development of se-lective acidizing technology for horizontal wells is particularly important. This paper presents a selective acidizing process by dragging coiled tubing in horizontal wells, which conducted experimental analysis and theory study for key operation parameters, and established technical parameters and successfully implemented on DH20-4H Well.
