In a geological section of Caspian basin stories of development and to structure lithologic complexes of rocks are allocated various on genesis: crystal base, terrigenous subsalt, carbonate subsalt, saliferous and oversalt structural and tectonic lithotechnical floors. The geological local structure of Astrakhan Anticline is dated for the ledge of the base of the same name and has the inherited character from its relief. In connection with the developed forecast of operation of the Astrakhan gas-condensate field till 2400, including with profitable production till 2222, additional researches of lithologic and technical properties and parameters of rocks of Caspian basin and its south-west part (Astrakhan Anticline and the Astrakhan gas-condensate field) are necessary. Specification of the lithotechnical parameters of rocks allows increasing prospects of profitable production of hydrocarbonic raw materials not only in the Astrakhan region, but also in other areas of the Caspian region and adjacent oil-and-gas bearing territories. Merging of group of rocks of the various stratigraphic levels in uniform lithotechnical complexes allows marking out more accurately and reasonably the oil-and-gas generating (maternal) breeds and breeds-collectors for accumulation and formation of deposits of hydrocarbons.
