Abstract

Geochemistry of underground waters of petróliferous deposits was studied in a vast region with different types of vertical hydrogeochemical zoning. It has been shown that the zoning nature is governed by two main factors: the genetic type of underground waters and character of water interaction with rocks and organic matter, which are, in turn, the products of the geological history of the region. According to genesis, the groundwaters are divided into four types: (1) sedimentogenetic Jurassic, (2) sedimentogenetic from the Paleozoic basement, (3) ancient infiltrated, and (4) condensated. The chemical composition of each of these types of water is considerably altered by water interaction with rocks, gases, and organic matter, as well as by mixing with waters of other genetic types. Different successions of genetic types of waters subjected to different grade metamorphism and mixing at depth are responsible for the character of direct, inverse, or more complicated hydrogeochemical zoning in the region.
