The article evaluates the engineering and geological conditions geological state of the stratigraphic complex of the Tengiz deposit. The conducted studies show the most complete, reliable and accessible information about the geological structure; engineering-geological sections were compiled with the differentiation of the geological environment into stratigraphic and genetic complexes and their constituent lithological and facies groups (engineering-geological elements-EGE). Complex data processing made it possible to determine the degree of facies heterogeneity of the main lithological and facies groups of soils. The studied territory is part of the Zhylyoysky district of the Atyrau region of the Republic of Kazakhstan and is located in the western part of the industrial zone of the Tengiz deposit. The soils formed as a result of the natural-historical process of the formation of the territory are divided into 3 stratigraphic-genetic complexes of unlicensed deposits. The first complex is represented by loamy silt (EGE-1), the second complex is sandy loam (EGE-2) and light powdery clay (EGE-3) and the third complex is represented by four deposits-Light arenaceous loam, excessively gypsumized (EGE-4), Arenaceous sandy loam (EGE-5), Light arenaceous loam, slightly gypsumized (EGE-6), Light arenaceous clay, moderately gypsumized (EGE-7). Highly aggressive to sulfates are Portland cement as per GOST 10178 grades W6, W8, W10-W14, W16-W20, W4; moderately and slightly aggressive Portland cement as per GOST 10178 withpercentage of C3 S not more than 65%, C3 A not more than 7%, C3 A + C4 AF not more than 22% and blast-furnace cement’s grade of W6 and W8. Highly aggressive to chlorides are all of grades of Portland cement.
