摘要

The characteristics of recovery of high-molecular-mass compounds in various model systems reflecting the reservoir structure were studied with the use of the technique of cyclic solvent (toluene and diesel fuel) flooding and dissolving these compounds over a given period of time at temperatures of 30 and 70掳C. The dynamics of recovery of the macromolecular compounds showed that the major portion of soluble compounds was extracted in the first 3–5 cycles, and the rock permeability substantially increased.
