FIELD: oil-and gas industry. ^ SUBSTANCE: according to production layer and saturating reservoir oil preliminary geophysical and hydrodynamic analysis define intervals of permeability value change and oil saturation with gas pressure Divide interval on maximum, minimum and at least one intermediate value according to permeability and oil saturation with gas pressure values Execute heat transfer agent flushing through the every model with simultaneous oil displacement from model dynamics and pressure gradient recording, according to which calculate oil flushing factors and oil and heat transferring agent phase permeability Correlate received values and according to the correlation results select heat transfer agent type and oil flushing regime for the reservoir under research. ^ EFFECT: reservoir condition modeling mistake decreasing, more reliable highly viscous oil displacement factor estimation for the lightly cemented collectors, and possibility to estimate rational thermal reservoir treatment at initial production stage, because of imitation of oil displacement process from lightly cemented collectors at a wide range of permeability and heat transfer agents displacement regimes. ^ 4 cl, 2 ex |
