摘要
封隔器在完井作业中发挥着重要作用。本文设计出一种爪套式封隔器,其具有坐挂安全可靠、避免封隔器提前坐挂、有效进行层间密封以及密封可靠等特点。该封隔器既可应用于套管内环空密封,又能实现裸眼井段的环空密封,实现井下完井作业的有效进行。
Packer plays an important role in well -completion practices. This paper designs a claw -shaped packer, which is safe and reliable in avoiding the hanging of packer before time, and achieving interlayer sealing effectively and reliably. The packer can be used not only for annulus seal in branch pipe, but also to realize the annular sealing in openhole section, so as to guarantee the effective operation of well - completion practice in the weU.
