Optimization of the CO2 concentration for gas reinjection flooding in HEI-59 oil-field
摘要
Abstract
Some of domestic oil fields are in the tertiary EOR phase .Carbon dioxide drive is an environmental friendly ,low carbon emission and high economic efficiency EOR method .The technique of gas reinjection ,as extension of Carbon dioxide drive tech ,the determination of the components is of great significance to the field oil recovery′s improvement .According to Song Liao Basin′s reservoir characteristics ,methods of experimental analysis and theoretical studies were combined .Phase behavior of reinjection gas was studied .Reinjection gas compo‐sition′s impact on the minimum miscibility pressure (MMP) was analyzed .Oil displacement efficiency characteristics under different CO2 purity were researched .Technical indicators of gas injection EOR were determined through combination of reservoir engineering and numer‐ical simulation methods .The result shows that when the concentration ratio of CO2 in rein‐jection gas is greater than 93% ,HEI‐59 reaches an optimal displacement characteristics .关键词
