WELL TEST INTERPRETATION MATHEMATICAL MODEL CONSIDERING ASYMMETRIC PREFERENTIAL SEEPAGE CHANNEL
摘要
Abstract
Under the influence of reservoir heterogeneity, the long-term flushing process by injected water and other factors, the asymmetric preferential seepage channels tend to appear extremely easily in oil reservoirs during the waterfiood development, therefore how to identify this kind of asymmetric preferential seepage channel has become a research hotspot. Based on basic principles of seepage flow mechanism, the point source solution of this kind of reservoir is obtained by mirror reaction, and then a bottom hole pressure response mathematical model with asymmetric preferential seepage channel is established through the integration along the extending direction of seepage channel.Moreover, the influencing factors of the bottomhole pressure dynamic response are analyzed. The high capacity channel in the reservoir can be identified effectively through the combination of the established mathematical model and field pressure test data, which provides a certain degree of guidance for profile control and water shutoff in oilfield and the selection of well sites and producing horizons.关键词
