新型Y341型封隔器的研制与应用

摘要

Top water exclusion is the main technology in casing damaged well recovery productivity of Longdong Oilfield. It revealed lots of problems at present. For example,the cycle of every mining was short,string occurred flexural deformation after setting,and eccentric wear was severe,oil tube squirm lost effectiveness and so on. So we developed new Y341 type low pressure packer. Through field application,the packer, with low pressure of setting,high success rate of every mining and recovery rate of production,has good application value.%隔水采油是陇东油田套损井恢复产能的主要技术,目前暴露出隔采周期短、坐封后管柱发生弯曲变形、偏磨严重、油管蠕动失效等问题.研制了新型Y341型低压力封隔器,经过现场应用,具有坐封压力低、隔采成功率高、产能恢复率高等优点,具有应用价值.
