Ukrainian energy balance is comprised of oil and gas in 60°/о. Annual use of natural gas in Ukraine will decrease gradually in 2030 down to 49,5 billion M3 according to energy strategy. Today Ukraine is one of those countries which do not have enough energy resources, besides it occupies 26th place in extraction of own energy resources and provides for itself only in 25°/о. Therefore there is а problem of overcoming the deficiency of oil-and-gas in the state by increasing drilling works and using new, progressive and energy-saving technologies. Therefore, in the following article the advanced way of calculation of hydraulic losses of pressure for pipes of different types of one diameter is caused by design features, namely lengths of the boring lock. The expenses of hydraulic capacity for аll types of boring pipes was calculated and it showed that designs with landing deep into were the most power-consuming. It is better to use pipes with landing on from the outside from the point of view of minimization of hydraulic power inputs at drilling boreholes.
