The article is devoted to the analysis of the causes of complications arising at the penetration of the post-salt, salt and pre-salt sections of the Astrakhan GCF. It has been established that a number of factors affect the occurrence of a number of complications: both of natural (salt tectogenesis, the presence of viscous plastic salts and clays, fracturing) and technogenic nature (speed of the tripping operations, pump productivity, high density of drilling and cement mortars, induced pressure). Five main absorption intervals were identified in the deposit section and the causes of their occurrence were considered. The article also contains recommendations for preventing possible complications.
