Annotation:
The authors of the article consider the possibility of applying the Buckley-Leverett theory with the Weldge method to calculate the indicators of oil displacement from the bottomhole formation zone during the initial opening. The Weldge method is based on the analysis of the curve of the phase flow distribution function in case of a two-phase filtration. This method can be used when designing the process of a productive formation opening and choosing a flushing fluid.
