Methodical basics of geochemical methods of search of oil and gas fields are covered In the article. It is shown that hydro carbonic gases (HCG) interacting with breeds and waters at vertical migration, not only form the specific geochemical field, but also changes structure of breeds, and concentrates noticeable quantity of HCG and minerals. Researches of element and gas structure of breeds at various depths of the section, earlier drilled wells, showed that this information can be used for increase in reliability of forecasts at search drillings. The algorithm is developed for calculation of the relations of concentration of separate elements.
Getter properties of breeds depending on a specific surface area (aggregate size) also were investigated. The value of an absorption coefficient increases with increase in a molecular mass of hydrocarbon (HC), clay breeds are capable to concentrate the significant amount of HCG
