Abstract: the proposed article discusses the design of calculation and selection of technological parameters of the drilling mode of a directional production and evaluation well for the purpose of successful drilling of well No. 707 at the Western Cheleken field in the coastal zones of the coastal waters of the Caspian Sea. For the design calculation and selection of technological parameters of the drilling mode were used: - the results of studies of drilling support wells on a given area or on areas with similar geological conditions. - if drilling has not yet been carried out on the well area, statistical data are insufficient and the ability to represent the properties of rocks is only approximate, then axial loads can be approximately set in accordance with the selected bits, their passport data and drilling experience with similar geological conditions. - data on the durability of the bits and the mechanical speed obtained from the results of working out the bits in this area from previously drilled wells. This work can be used to perform the tasks set when drilling directional wells and to design the calculation and selection of technological parameters of the drilling regime in extremely difficult mining and geological conditions at abnormally high reservoir pressures.
Key words: drilling mud, hardness, abrasiveness, plasticity, downhole motor, flushing holes of the bit, manifold, downhole, profile, drilling mode.
