Induced by acoustic fieldsprocesses of structure formation in high-molecular media

Abstract

The paper considers the mechanisms of destruction and synthesis of macromolecules, which can be stimulated by external acoustic fields in a two-phase, oil dispersed medium containing a large number of gas bubbles. It is assumed that the dynamics of these bub-bles depends on changes in the geometry of the flow and the excitation of sound vibra-tions in the flow. Particular attention is paid to the process of changing the density of a liquid due to the effect of an internal airlift in a liquid dispersed medium. Mechanically induced kinetic changes in macromolecules (destruction and synthesis of colloidal chains) can occur when bubbles collapse. These features can be used in oil processing and well logging to assess oil saturation of reservoirs.
