Cup packer is mainly composed of upper joint, cup and center tube.
Cup packer is a kind of self-sealing 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.
