Autor: Vasyl Boryn, Andrii Lahoida, Vasyl Sheketa, Georgiy Sementsov

Publikováno v: Eastern-European Journal of Enterprise Technologies, Vol 4, Iss 2 (106), Pp 82-94 (2020)

This paper addresses control over flushing a well, which belongs to the class of non-stationary dynamic stochastic objects. The object evolves over time and has a large transport delay, which increases with an increase in the well's length. The curre

Modeling of dynamic stability of the well deepening process based on the catastrophe theory

Autor: Georgiy Sementsov, Vitaliai Kropyvnytska, Andrii Lahoida, Taras Humenuik

Publikováno v: Eastern-European Journal of Enterprise Technologies, Vol 4, Iss 3 (94), Pp 36-46 (2018)

Theoretical aspects of the catastrophe theory were considered and the possibility of application of the catastrophe theory methods in estimation of actual data of geological and technical control of the well deepening process were described. A method
