Abstract
Combustion tube experiments were carried out to investigate the basic behavior of fireflooding as an EOR method. And it was found that the vaporization-condensation mechanism was important to accumulate oil for making oill banks and oil banks formed moved toward the exit (production well).
As to the production, three stages would be seen. These are (1) the production of oil movable at a liquid state, (2) production of oil from the oil bank formed by means of fireflooding mechanism mentioned above, and (3) little production of oil after the production of oil bank. When the oil is at the residual oil saturation in the reservoir, no oil production at the first stage would be expected.
Adequacy of the simulator developed in the present study and described in the last paper was examined in detail by means of comparing results obtained both theoretically and experimentally. And it was shown that the simulator was preferable.
