Abstract

Abstract: Expansion test, as an important screening tool, is applied widely in miscible flooding and CO2well stimulation. The influ-ences of injection gas on physical behaviors of crude were report-ed in the literatures in petroleum industry. Unfortunately, a few reports on the screening for the injection gas were publicized in the past decades. In this paper, PVT tests were carried out
to investigate the influences of such injection gases as CO2, N2 and CH4on expansion factor and bubble point. The results from PVT tests indicated that CO2is the most favorable injection gas for well stimulation in Jiangsu oilfield.

Key words: phase behavior, well stimulation, miscibility, injection gas, CO2
