Cup Packer

Cup packer can be used for oil extraction, mechanical pluggingother constructions.

1. Application


Cup packer can be used for oil extraction, mechanical plugging and other constructions.


2. Structure and Work Principle


Cup packer is mainly composed of upper joint, cup and center tube.

Cup packer is a kind of selfsealing packer. The pipe annulus is sealed by interference cup and casing inwall. On the impact of downhole pressure difference, cup expanses to seal the annulus and it just can bear one-way big pressure differential.

Cone cup is the main part of cup packer. It is vulcanized rubber on the metal frame. Cup packer is used in well together with other downhole tools. When the tool down to the designed position, it’s sealed by compression between cup and inwall and pressure difference. Pull the column to realize unsealing.


3. Characteristics


a. There is no anchoring mechanism. It can be used in vertical, deflecting and horizontal well. The use grade is unlimited.

b. Cup can be facing fixed (maintain the pressure from two directions), or fixed in the same direction (upward or downward). Cup can be fixed in any direction and easy to dismount.

c. Can realize sealing and unsealing without any other power equipment. It doesn’t need moving column or giving pressure to realize sealing. Put downward together with the tube string can realize sealing casing annulus. Save more operation time and cost.
