This article is dedicated to the casting technology in oil and gas industry, representing a complex of industrial enterprises for the extraction, transportation, processing and distribution of final products of oil and gas refining. Many components used in machines and equipment of the oil and gas complex are made by casting. Casting is one of the oldest and main methods of obtaining metal products and blanks. The main advantage of casting production in oil and gas industry is that it is possible to produce any component or spare part of the machine and equipment used in the extraction of oil and gas of various configurations and masses. Oil and gas equipment is a product operating under difficult climatic conditions, therefore the used parts manufactured by casting must have high accuracy and sufficient strength, i.e. have improved operational performance characteristics.

Absract: This article considers the design features of drilling rigs intended for drilling vertical and inclined boreholes.
