In order to study the self-developed YQH-100-type multistage oil-gas mixed pump,the Mixture model was utilized, the standard k -εturbulence model was selected and the Simple algorithms was used for the calculation of velocity pressure cou-pling .The numerical simulation was carried out for the three different gaps of axial gap of the Oil-Gas multiphase Pump under the condition that the GVF are 0,10%,30%,50%,70%,respectively.The pressure distribution on the coupling plane was obtainer and the variation of the head and efficiency of the oil-gas multiphase pump with the GVF in different variation of gap of movable-Static-movable-Static vane.And the results indicated that the head and efficiency with the growth gap is the highest.
