METHOD FOR DECREASING THE SORPTION LOSSES OF SECONDARY AND TERTIARY OIL PRODUCTION BY THE APPLICATION OF SURFACE ACTIVE MATERIALS AND BY SIMULTANEOUS INHIBITING CLAY MINERALS

摘要

Potassium, ammonium and/or zirkonium ions, or other hydrated cations of0.13-0.15 nm and of coordination number 12, whose swelling capacity in clay media reduces the porosity, dispersive losses, sorption capacity and stabilises the rock permeability are added to the reagents during petroleum prodn. in order to reduce petroleum losses and reduce costs.
