Abstract

Abstract: It is an important way to enhance oil recovery through gas injection after injecting water. The efficiency of EOR of carbon dioxide injection relates closely to the properties of crude oil.Whether carbon dioxide injection can be conducted will be decided according to PVT parameters, MMP of crude oil with
CO₂ and crude oil properties after CO₂ injection. We pick 5 typical oil samples from different oil companies in Liaohe oil field study the phase behavior characterization and analyze the oil properties after the crude oil is miscible with CO₂. We also measured the minimum miscible pressures of two oil samples,according to which we evaluated the crude oil properties and an-
alyze the possibility of CO₂ injection. The results showed that CO₂injection in Liaohe light oil district can enhance oil recovery, but it is difficult for crude oil to be miscible with injected CO₂.

Key words: enhanced oil recovery, carbon dioxide injection, PVT, Liaohe oil field
