Oil washing-off surfactant POLYPAV

Oil washing-off surfactant POLYPAV 

TU 2480-061-53501222-2010

Complex chemical POLYPAV is designed to provide better final washing off the film oil during water injection into injection wells and also during conversion of the production wells into injection wells. It is used as:

  • Oil washing off chemical,
  • Component of viscopolymer and acidizing systems ,
  • Component in the technology of removing of asphaltene-resin-paraffin deposits,
  • Agent for lowering of pumping pressure for polymer systems injected into injection wells at the well injectivity leveling.

Complex chemical POLYPAV is a synergetic composition of nonionic and anionic surfactants in water solution.

POLYPAV is available in two grades: POLYPAV 81-B and POLYPAV 81-V varying with nonionic and anionic surfactants mass ratio and having different application area.

Application Area

  • Treatment of injection wells with sand inflow and with the presence of sand plugs.
  • Bottomhole flushing prior to the procedures the treatment of critical area of formation in injection wells. 
  • Squeezing of the acidizing fluids into the formation at the operations of improving the injectivity of injection wells.
  • Cleaning of lifting pipes, oil-field distribution piping and pipelines from the contamination left after the treatment of wax and paraffins with organic dissolvents.
  • Killing of injection wells at maintenance operations.
  • Pumping of the chemical as a part of polymer systems into injection wells (POLYPAV 81 grade V is used for pumping pressure reduction).
  • Treatment of production wells complicated with asphaltene-resin-paraffin deposits.  

Properties
