【 摘 要 】

By the process of gas injection under miscible conditions, the

(alai oil recovery also includes vaporized hydrocarbons from the

residual immobile oil, in addition to the oil produced by direct displacement.

The process is complex and involves the influence of the interaction of extracted hydrocarbons and in-situ oil at the displacement front. Therefore, the final oil recovery under miscible conditions is higher than the "conventionally" displaced oil. Methods of calculating multiple contacts miscibility with an Equation of State (EOS) determine the miscibility conditions by simulation processes as a vaporizing gas drive or condensing gas drive. The aim of this study was to determine a degree of miscibility.
