摘要
长庆油田注气驱油先导性试验预计将在低渗透的安塞油田坪桥区进行。作为室内前期工作，研究了安塞长６层原油与长庆气田天然气及长庆气田天然气／马岭炼厂液化气混合气之间的混相性质，测定了油气混合体系中气相的组成、油相中溶解气体的组成及油相（溶气原油）的高压物性。研究结果表明，对于安塞长６层原油。
This paper presents the results of preliminary laboratory studies for a roughly planned gas flood pilot program at low permeability Pingqiao district, Ansai, Changqing. The miscibility of C6 layer crude oil of Ansai with natural gas and with a natural/liquid gas mixture (8∶2) is experimentally investigated, the composition of the gas phase and of the dissolved gases in the oil phase is analyzed chromatographically and the physical properties of the oil phase (the crude oil with dissolved gases) are determined at high pressures. It is shown that for the crude oil under study, natural/liquid gas mixtures are more effective driving gas than natural gas does.
