Experimental Reaserch And Numerical Simulation Of Thermal Flooding Process Of In-Situ Combustion

The numerical simulation of reservoir began in the50’s of the20th century. With thedevelopment of the reservoir engineering percolation theory, mathematical theory ofcomputing and computer technology, it has become an emerging discipline. By the analysisof reservoir fluid situation，it can forecast the future of dynamic reservoir, find the means ofimproving the ultimate recovery rate and guide production. For oil and gas fielddevelopment and reservoir engineering study has provided the means of modern,so itbecome an indispensable tool to reservoir engineering and technical personnel. The mainreaserch work of this article:1. In one dimentionsional combustion tube indoor simulation experiment deviceplatform, during the process of thermal flooding of in-situ combustion dry and wet forwardfor combustion technology were studied respectively. The combustion characteristic ofsample oil parameters, burning the advancing speed front and oil recovery rate weredetermined and the air/crude oil ratio, the utilization efficiency of oxygen index werecalculated in these two kinds of technology conditions.2. A one dimentionsional mathematical model was established to describe theexperimental in-situ combustion process. The method within a wide range of variousparameters was solved by using finite difference method. The effects of some importantparameters on oil recovery, air consumption and advancing velocity of combustion frontwere investigated.
