分级解封长胶筒封隔器的结构及性能分析

Structure and Performance Analysis of Gradual Releasing Long Tubing Packer

针对特高含水期精细分层注水存在的多级封隔器解封困难,以及小隔层分层注水封隔器偏离隔层现象,研制了分级解封长胶筒封隔器。该封隔器能够实现分级解封,解封力小,结构简单,容易操作。利用ABAQUS有限元分析软件对封隔器的长胶筒进行分析,确保长胶筒的密封及锚定功能的可靠性。

In the extra high wa packer in the process of the fin appear jammed phenomenon in veloped,which can realize the f ter cut period, there are some releasing difficulties of multilevel e layering water injection,and layering water injection packer will small interlayer,so a releasing gradual long tubing packer was de- unction of grading unlock, small unlock force, simple structure and easy to operate. Using the ABAQUS finite element analysis software, the long rubber tube was analyzed to ensure the long rubber tube sealing and the realization of the function of anchor.
