Annotation:

The article presents a semi-analytical solution of the system of the CRM-model differential equations for analyzing a group of wells watering under the elastic watering mode-of development taking into account interaction of producing wells. An example of field data analysis using the proposed model is considered. Good results of coincidence of calculated and actual flow rate and bottomhole pressure curves in comparison with the model without interference are obtained. Several models of wells watering by flowing water are proposed, taking into account production wells interference. The field data show that taking into account such interference increases calculation accuracy.
