丢手工具是丢手工艺技术的关键工具之一 ,丢手工具性能的优劣直接决定着丢手工艺的施工成功率。一种新型的液压丢手工具 ,使现场施工成功率达到了 1 0 0 %。利用这种丢手工具与液压式封隔器配套使用 ,可实现一次加液压使封隔器座封和丢手 ,简化施工工艺 ,该工具已广泛应用于多种采油工艺管柱中。 Losing hand tools is one of the key tools throwing handicrafts and technology, the pros and cons of throwing hand tools directly determines the success rate of throwing handicraft construction. A new type of hydraulic throwing tool, the success rate of on-site construction reached 100%. The use of such throw-away tools in conjunction with a hydraulic packer allows for a single hydraulically-assisted packer seat-sealing and throw-away, simplifying the construction process and has been used extensively in a variety of production process columns.
