Emphasis is placed on the historical institution of science and production, providing the domestic economy with its energy resources, and ways to implement this vital task at the expense of its potential. Considering the depletion of the primary resources of oil and gas, an effective way to increase the coefficient of oil and gas inclusion from productive horizons is indicated through modern coil tubing technologies. The publication’s study object is a flexible drill stem in a directional well, and the subject of the study is its load due to axial movement along the axis of the mine. The possibility of using coil tubing means has been analyzed, and the technological advantages and disadvantages of their use for drilling directed wells in Ukraine have been estimated. Research methods of pressing forces of coiled tubing to walls of the directed well, taking into account constructive and technological aspects of the process and conditions of the interaction of a column of pipes with walls of mining, have been systematized. It has been established that with available scientific and methodological support, it is possible to estimate the load of the flexible pipe column when performing various technological operations, which are accompanied by axial movement along the axis of the directed well
