介绍了一种液压式电缆桥塞座封工具的工作原理,设计方案以及现场应用情况.液压式座封工具通过液柱压力可以实现桥塞座封,动力来源为井内液柱压力,不需要民爆物品,与目前采用火药燃烧提供动力源的座封工具相比较,不仅消除了民爆物品给生产组织带来的不便及安全隐患,而且使用后不会产生工业废料,更加安全环保.为油气田电缆座封桥塞的封层需求提供不同的工艺技术参考.
The working principle,design scheme and field application of a hydraulic bridge plug sealing tool are introduced.It can realize sealing by the liquid column pressure.The power is from liquid column pressure in well without civil explosives.Compared with propellant combustion power source to provide a seal tool,this tool not only eliminates the inconvenience and safety hidden trouble,but also does not produce industrial waste with more safety and environmental protection.It provides technical reference for different oilfield packer cable bridge plug seal requirement.
