    摘要: 目前,在完井作业尤其是水平井的分段完井或分段卡封中,现有管外封隔器的坐封工艺不能保证坐封良好,因此本文设计了一种管外封隔器组合注入工具,利用其上、下两端的胶筒实现密封,中间的注入孔道实现对管外封隔器胀封液的注入,可实现管外封隔器的有效坐封,注入水泥则可实现其永久坐封,提高分段完井或分段卡封工艺的有效期。通过现场应用表明,该工具可靠有效,能够适应分段完井或分段卡封工艺的长期有效应用。 Now, in the completion operation, especially in the staged completion and staged plugging, the seating process can’t promise successful sealing. So the combined injection tool for external casing packer is designed. The top and bottom packers are used for sealing; the middle hole is applied to inject fluid for seating packer. If the fluid is cement, ECP (external casing packer) is seating for permanent. The validity of segmental completion and segmental plugging is longer. Through the field application, the tool is reliable and effective in segmental completion and segmental plugging technology.
