Laboratory Studies of High-Temperature-Compound Steam Drive on Heavy Oil

Abstract:

This paper presents experimental work on the research of the mechanism of oil displacement of steam drive and high-temperature-compound steam drive, which in order to improve the conventional steam drive technology and increase the recovery of heavy oil. Many experiments were done with the sand-packed model under the formation condition. The results show that: (a) the high-temperature-compound steam drive could extend the water breakthrough time, increase the permeability of oil phase, reduce the residual oil saturation; (b) reducing the viscosity by CO2 dissolution, maintaining the pressure, improving the oil flow ratio, dissolved gas drive，Improving oil displacement efficiency，all of above were the increase production mechanism of high- temperature-compound steam drive.
