Packer

Water Based Swellable Packer(Normal)

Features

  • Metal ring design of the rubber sleeve: metal ring protects the rubber sleeve prevents projecting and destroyed of the end ensuring the pressure rating of the end.
  • High temperature Sulfuration technology is applied in swell rubber to splice to central pipe in any size, assuring flexible design on the structure and special size requirement from the customers.
  • Seal rubber sleeve: slow swell, fast swell
  • Various sleeve design: successive, segmental
  • Favorable seal for the irregular wellbore, no need of the tools and the positional engineer.
  • No retraction after the self-expansion of the rubber. 
  • The expanded shape of the packer will be kept even changing the immersion media.
Technical Advantage
  • Under pressure:10000PSI
  • Expansion speed of the swellable material is controllable.
  • Temperature under 150℃
  • Running life is more than 10 years
  • Corrosion resistant rubber is applied to resist acid, soda, CO2 、H2S…

Notice 1 : Max OD and the sealing length can be designed according to the special requirement from the customers.

Notice 2: Determination conditons of rated pressure : the max OD of rubber sleeve and the max ID of tested casing pipe should be selected


Applications
  • Open-hole stages completion for horizontal well
  • Screen stages completion
  • Stages Gravel completion
  • Oil layer stages reform
  • Later ponding, test and stimulation of stages completion in horizontal well.
  • Cementation security
 
Water/Oil Based Swellable Packer (high temperature)

In order to make sure the production of heavy well with steam injection under high temperature, we import high temperature rubber technology from outside, exploring swellable packer (high temperature) system.

Features
  • Max temperature rating of 575 F (302 C)
  • Working pressure rating of 50MPa
  • Running life in ultimate condition: no longer than 10 years .
Advantage
  • Special design for rubber sleeve protection, the extendable/collapsible baffle rings in the connection of the end can be found. 
  • Elastomer for high temperature with special formula is applied in the rubber sleeve.
  • Suitable used in any open-hole well and casing.
Applications
  • High temperature steam injection
  • Well in high temperature
