The Application of Production Well Testing Curve in ASP Flooding Tracking and Adjusting

In order to ensure individualistic and timely adjustment of ASP flooding tracking, further improve quality and efficiency, and ensure the development effect of combination flooding, it is urgent to enrich dynamic analysis application data, improve the predictive and targeted adjustment. By tapping well testing data that contains a large amount of reservoir information which can reflect the dynamic changes of underground fluids, and based on fluid approximation in blank water flooding reservoirs, comprehensive geological characteristics and well testing curves reflect the characteristics of inter well reservoirs, well groups are divided into five categories based on the characteristics of well testing curves. According to the classification of well groups, the changes in well testing curves during the ASP flooding process are analyzed. It Revealed that the variation of inter well fluidity during the flooding process reflected by the curve. The dynamic analysis has developed from well points to a full well group of “well point dynamics + inter well fluid changes”. The tracking and adjustment of advanced prediction and individualistic matching is achieved.It is improved that the timeliness and effectiveness of adjustment strategies. The provided technical has supported for the improvement of quality and efficiency in the industrial application of ASP flooding.It has been becoming an important technical means to ensure the promotion and application effect of ASP flooding.
