            y241封隔器

              詳細說明

              —、作用與原理: 

              該封隔器為水力坐封、單向錨定、機械鎖緊,封隔器坐封后自動鎖定,使封隔件處于永久密封狀態,卡瓦處于單向錨定,密封性能可靠。具有操作簡單、性能可靠之優點,該封隔器可與水力錨配合使用于分層壓裂工藝。

              三、使用方法: 

              1. 根據設計及工藝要求選擇封隔器及配套工具并按要求配好管柱。

              2.  坐封:將管柱下至設計位置,從油管內投所需鋼球,待球落至球座(約30分鐘),再從油管內打液壓9-12MPa打開作封,18MPa穩壓5分鐘,即可完成封隔器的坐封。

              3. 解封:當需要起管柱時,上提時可達到10KN,可直接上提管柱即可使封隔器解封。順利起出封隔器及管柱。
