Annotation:
A new algorithm for the rational choice of a bottomhole type is proposed. The classical method of choosing the type of bottomhole is based on a "hard" binding to typical bottomhole is used, which meets certain geological-lithological conditions of the reservoir structure and wells operation methods. In real practice, there is no exact repetition of geological-lithological conditions, and well operation methods are also diverse. Therefore, there is a necessity of replacing the classical "rigid models" of the choice of bottomhole designs types by more "flexible models". The presented algorithm will be implemented in an automated system for selecting the optimal design and rational method of wells completion according to the existing geological-lithological conditions of the reservoir structure and reservoir operating conditions.
