Abstract: the article considers the design of the bottom-hole assembly (BHA) of the technical column of intervals (a set of zenith, rectilinear) of an obliquely directed operational evaluation well for the purpose of successful drilling of well № 707 at the Western Cheleken field in the coastal zones of the coastal waters of the Caspian Sea. Materials of previously drilled wells and standard calculations, as well as safety rules in the oil and gas industry, were used to design the BHA of the intermediate technical column of the well. The application of new downhole equipment for the selection of the zenith angle and logging operations during drilling in real time is described. This work can be used to perform the tasks set when drilling directional wells in fields with difficult mining and geological conditions and abnormally high reservoir pressure.
Key words: technical column, design, flushing fluid, drill string, bending, calibrator, compression, curvature, check valve, rotary controlled system, translator, nipple, clutch.
