针对封隔器现状 ,与阜新石油工具厂合作 ,联合研制了Fxy44 5— 114自验封封隔器。该封隔器可以实现 :①上、下卡水工具一次性下井、一次性坐验封、一次性解封、一次性打捞 ,减少作业程序 ;②上、下卡水工具间的卡距不受限制 ;③在胶筒下面采用双向弧形球面卡瓦 ,使坐封均匀可靠 ,避免管柱卡井现象 ;④步进机构锁紧 ,使坐封后不松动、不退位 ,能够承受较高的双向压差 ;⑤自验封功能使坐封简单科学 ,保证验封的可靠性 ,解决了漏失井验封失真的问题。文中分析了Fxy44 5— 114封隔器的结构特点、工作原理、技术特点及现场应用情况
In view of the status quo of packer, cooperated with Fuxin Petroleum Tools Factory and jointly developed Fxy44 5- 114 self-sealing packer. The packer can be realized as follows: (1) The upper and lower card tools go down at one time, one-time sitting seal, one-time unsealing and one-time salvage to reduce the working procedure; (2) Limit; ③ Under the plastic cylinder with two-way curved spherical slips, so that the seal is uniform and reliable, to avoid the phenomenon of column well card; ④ step body locking, so that after the set is not loose, not abdicate, can withstand higher Bidirectional pressure difference; ⑤ self-sealing function to set a simple seal science, to ensure the reliability of the inspection seal to solve the problem of missing well seal seal distortion. In this paper, the structural characteristics, working principle, technical characteristics and field application of Fxy44 5- 114 packer are analyzed
