Abstract:

In order to determineminimum miscibility pressure (MMP) inYushulin oil field, a newmethod was carried out and perfected basing traditional tests. The means ofmicrocosmic experimentprimarilywas used to searchMMP between oil and CO2,and in order to contrast the resultslim-tube and long core experimentation were carried on. These proved that the comprehensive
result ismore accurate and audio-visua.l As a result, MMPwas determined and at the same time the reliability of determining MMP according to microcosmic experimental resultwas verified.

Key words: CO2miscible flooding, minimum miscibility pressure, enhanced oil recovery, newmethod
