摘　　要：针对水平井酸化出现的布酸不均匀和酸化后效果较差问题,结合油井完井方式,提出了水平井均匀酸化的研究思路。通过理论分析和室内实验研究,开发出能实现均匀酸化的布酸管柱和配套工具,形成了根据油层段特性改造的可控酸化技术。经过冀东油田、辽河油田等多口井的成功应用,表明该工具在酸化改造中应用效果理想,成功率高,具有广阔的应用前景。Horizontal well acidification is one of the effective methods. Recently based on the necessity for uneven acidification and side effects of horizontal well, and combining the various completion well methods, the research methods of homogeneous acidification technology of horizontal well were determined. By theory analysis and laboratory study, the homogeneous acidification distributing pipe string and corresponding acidification tools were developed; controlled acidification technology had been come into being. The success application in Jidong Oilfield and LIAOHE Oilfield, string and corresponding acidification tools get desired effect and higher success rate, and provide broad prospects of horizontal well acidification in future.
