The subjects of selection of optimal functional structure for drilling rigs used at the oil wells construction have been touched upon in the paper. One of the main principles for drilling equipment selection is minimization of production cost and reduction of wells construction time cycle. Determination of correlation between mining and geological conditions of oil wells drilling and technical and economic parameters of drilling rigs has been allows to optimize their use in accordance with minimization criterion of production cost. The correlation between type (cost) of drilling rig and reduced cost per unit for wells construction has been determined with use of overall index considering design and technological features of wells construction. Applying minimization criterion of cost, it is possible to select type of drilling rig which exploitation will be economically feasible for oil well construction with given design-technological complexity. The obtained results can be used by oil and gas extraction enterprises for the purpose of their manufacturing facilities effective distribution in accordance with drilling program.
