MODIFICATION OF RHEOLOGICAL PROPERTIES OF VISCOELASTIC SURFACE ACTIVE SUBSTANCE

摘要

FIELD: oil and gas production. ^ SUBSTANCE: modifier reducing time for recovery upon effect of shearing force of liquid medium on base of viscoelastic surface-active substance for process treatment of underground bed of deposit corresponds to fibrous substance or substance in form of particles, or their mixture in concentration sufficient for time of recovery upon effect of shearing force equal to 60 seconds or less, where concentration amounts to approximately 0.0001% to approximately 5 % wt of total weight of liquid medium. The inventions are developed in dependent points. ^ EFFECT: facilitation of time for recovery of fluid medium upon effect of shear force equal to 60 seconds or less. ^ 20 cl, 1 tbl
